=== eps8266 pin usage ===
 +
 +
Best Pins to Use – ESP8266
 +
 +
One important thing to notice about ESP8266 is that the GPIO number doesn’t match the label on the board silkscreen. For example, D0 corresponds to GPIO16 and D1 corresponds to GPIO5.
 +
 +
The following table shows the correspondence between the labels on the silkscreen and the GPIO number as well as what pins are the best to use in your projects, and which ones you need to be cautious.
 +
 +
The pins highlighted in green are OK to use. The ones highlighted in yellow are OK to use, but you need to pay attention because they may have unexpected behavior mainly at boot. The pins highlighted in red are not recommended to use as inputs or outputs.
 +
Label GPIO Input Output Notes
 +
D0 GPIO16 no interrupt no PWM or I2C support HIGH at boot
 +
used to wake up from deep sleep
 +
D1 GPIO5 OK OK often used as SCL (I2C)
 +
D2 GPIO4 OK OK often used as SDA (I2C)
 +
D3 GPIO0 pulled up OK connected to FLASH button, boot fails if pulled LOW
 +
D4 GPIO2 pulled up OK HIGH at boot
 +
connected to on-board LED, boot fails if pulled LOW
 +
D5 GPIO14 OK OK SPI (SCLK)
 +
D6 GPIO12 OK OK SPI (MISO)
 +
D7 GPIO13 OK OK SPI (MOSI)
 +
D8 GPIO15 pulled to GND OK SPI (CS)
 +
Boot fails if pulled HIGH
 +
RX GPIO3 OK RX pin HIGH at boot
 +
TX GPIO1 TX pin OK HIGH at boot
 +
debug output at boot, boot fails if pulled LOW

Continue reading for a more detailled and in-depth analysis of the ESP8266 GPIOs and its functions.
 +
GPIOs connected to the Flash Chip
 +
 +
GPIO6 to GPIO11 are usually connected to the flash chip in ESP8266 boards. So, these pins are not recommended to use.
 +
Pins used during Boot
 +
 +
The ESP8266 can be prevented from booting if some pins are pulled LOW or HIGH. The following list shows the state of the following pins on BOOT:
 +
 +
    GPIO16: pin is high at BOOT
 +
    GPIO0: boot failure if pulled LOW
 +
    GPIO2: pin is high on BOOT, boot failure if pulled LOW
 +
    GPIO15: boot failure if pulled HIGH
 +
    GPIO3: pin is high at BOOT
 +
    GPIO1: pin is high at BOOT, boot failure if pulled LOW
 +
    GPIO10: pin is high at BOOT
 +
    GPIO9: pin is high at BOOT
 +
 +
Pins HIGH at Boot
 +
 +
There are certain pins that output a 3.3V signal when the ESP8266 boots. This may be problematic if you have relays or other peripherals connected to those GPIOs. The following GPIOs output a HIGH signal on boot:
 +
 +
    GPIO16
 +
    GPIO3
 +
    GPIO1
 +
    GPIO10
 +
    GPIO9
 +
 +
Additionally, the other GPIOs, except GPIO5 and GPIO4, can output a low-voltage signal at boot, which can be problematic if these are connected to transistors or relays. You can read this article that investigates the state and behavior of each GPIO on boot.
 +
 +
GPIO4 and GPIO5 are the most safe to use GPIOs if you want to operate relays.
 +

 +
Analog Input
 +
 +
The ESP8266 only supports analog reading in one GPIO. That GPIO is called ADC0 and it is usually marked on the silkscreen as A0.
 +
 +
The maximum input voltage of the ADC0 pin is 0 to 1V if you’re using the ESP8266 bare chip. If you’re using a development board like the ESP8266 12-E NodeMCU kit, the voltage input range is 0 to 3.3V because these boards contain an internal voltage divider.
 +
 +
You can learn how to use analog reading with the ESP8266 with the following guide:
 +
 +
    ESP8266 ADC – Read Analog Values with Arduino IDE, MicroPython and Lua
 +
 +
On-board LED
 +
 +
Most of the ESP8266 development boards have a built-in LED. This LED is usually connected to GPIO2.
 +
ESP8266 NodeMCU On-board LED
 +
 +
The LED is connected to a pull-down resistor, so when you send a HIGH signal the LED turns off.
 +
RST Pin
 +
 +
When the RST pin is pulled LOW, the ESP8266 resets. This is the same as pressing the on-board RESET button.
 +
ESP8266 NodeMCU On-board Reset button
 +

 +
GPIO0
 +
 +
When GPIO0 is pulled LOW, it sets the ESP8266 into bootloader mode. This is the same as pressing the on-board FLASH/BOOT button.
 +
ESP8266 NodeMCU GPIO 0 Flash boot button
 +
GPIO16
 +
 +
GPIO16 can be used to wake up the ESP8266 from deep sleep. To wake up the ESP8266 from deep sleep, GPIO16 should be connected to the RST pin. Learn how to put the ESP8266 into deep sleep mode:
 +
 +
    ESP8266 Deep Sleep with Arduino IDE
 +
    ESP8266 Deep Sleep with MicroPython
 +
 +
I2C
 +
 +
The ESP8266 doens’t have hardware I2C pins, but it can be implemented in software. So you can use any GPIOs as I2C. Usually, the following GPIOs are used as I2C pins:
 +
Report this ad
 +
 +
    GPIO5: SCL
 +
    GPIO4: SDA
 +
 +
SPI
 +
 +
The pins used as SPI in the ESP8266 are:
 +
 +
    GPIO12: MOSI
 +
    GPIO13: MISO
 +
    GPIO14: SCLK
 +
    GPIO15: CS
 +
 +
PWM Pins
 +
 +
ESP8266 allows software PWM in all I/O pins: GPIO0 to GPIO16. PWM signals on ESP8266 have 10-bit resolution. Learn how to use ESP8266 PWM pins:

OLED

Introduce:

What is OLED? OLED (Organic Light-Emitting Diode) is a self light-emitting technology composed of a thin, multi-layered organic film placed between an anode and cathode. In contrast to LCD technology, OLED does not require a backlight. OLED possesses high application potential for virtually all types of displays and is regarded as the ultimate technology for the next generation of flat-panel displays.

How Does OLED Emit Light? OLEDs basic structure consists of organic materials positioned between the cathode and the anode, which is composed of electric conductive transparent Indium Tin Oxide (ITO). The organic materials compose a multi-layered thin film, which includes the Hole Transporting Layer (HTL), Emission Layer (EML) and the Electron Transporting Layer (ETL). By applying the appropriate electric voltage, holes and electrons are injected into the EML from the anode and the cathode, respectively. The holes and electrons combine inside the EML to form excitons, after which electroluminescence occurs. The transfer material, emission layer material and choice of electrode are the key factors that determine the quality of OLED components.

No backlight, the display unit can be self-luminous
High resolution: 128 * 64
Viewing angle:> 160 °

eps8266 pin usage

Best Pins to Use – ESP8266

One important thing to notice about ESP8266 is that the GPIO number doesn’t match the label on the board silkscreen. For example, D0 corresponds to GPIO16 and D1 corresponds to GPIO5.

The following table shows the correspondence between the labels on the silkscreen and the GPIO number as well as what pins are the best to use in your projects, and which ones you need to be cautious.

The pins highlighted in green are OK to use. The ones highlighted in yellow are OK to use, but you need to pay attention because they may have unexpected behavior mainly at boot. The pins highlighted in red are not recommended to use as inputs or outputs. Label GPIO Input Output Notes D0 GPIO16 no interrupt no PWM or I2C support HIGH at boot used to wake up from deep sleep D1 GPIO5 OK OK often used as SCL (I2C) D2 GPIO4 OK OK often used as SDA (I2C) D3 GPIO0 pulled up OK connected to FLASH button, boot fails if pulled LOW D4 GPIO2 pulled up OK HIGH at boot connected to on-board LED, boot fails if pulled LOW D5 GPIO14 OK OK SPI (SCLK) D6 GPIO12 OK OK SPI (MISO) D7 GPIO13 OK OK SPI (MOSI) D8 GPIO15 pulled to GND OK SPI (CS) Boot fails if pulled HIGH RX GPIO3 OK RX pin HIGH at boot TX GPIO1 TX pin OK HIGH at boot debug output at boot, boot fails if pulled LOW A0 ADC0 Analog Input X Report this ad

Continue reading for a more detailled and in-depth analysis of the ESP8266 GPIOs and its functions. GPIOs connected to the Flash Chip

GPIO6 to GPIO11 are usually connected to the flash chip in ESP8266 boards. So, these pins are not recommended to use. Pins used during Boot

The ESP8266 can be prevented from booting if some pins are pulled LOW or HIGH. The following list shows the state of the following pins on BOOT: 

   GPIO16: pin is high at BOOT
   GPIO0: boot failure if pulled LOW
   GPIO2: pin is high on BOOT, boot failure if pulled LOW
   GPIO15: boot failure if pulled HIGH
   GPIO3: pin is high at BOOT
   GPIO1: pin is high at BOOT, boot failure if pulled LOW
   GPIO10: pin is high at BOOT
   GPIO9: pin is high at BOOT

Pins HIGH at Boot

There are certain pins that output a 3.3V signal when the ESP8266 boots. This may be problematic if you have relays or other peripherals connected to those GPIOs. The following GPIOs output a HIGH signal on boot: 

   GPIO16
   GPIO3
   GPIO1
   GPIO10
   GPIO9

Additionally, the other GPIOs, except GPIO5 and GPIO4, can output a low-voltage signal at boot, which can be problematic if these are connected to transistors or relays. You can read this article that investigates the state and behavior of each GPIO on boot.

GPIO4 and GPIO5 are the most safe to use GPIOs if you want to operate relays. Report this ad Analog Input

The ESP8266 only supports analog reading in one GPIO. That GPIO is called ADC0 and it is usually marked on the silkscreen as A0.

The maximum input voltage of the ADC0 pin is 0 to 1V if you’re using the ESP8266 bare chip. If you’re using a development board like the ESP8266 12-E NodeMCU kit, the voltage input range is 0 to 3.3V because these boards contain an internal voltage divider.

You can learn how to use analog reading with the ESP8266 with the following guide: 

   ESP8266 ADC – Read Analog Values with Arduino IDE, MicroPython and Lua

On-board LED

Most of the ESP8266 development boards have a built-in LED. This LED is usually connected to GPIO2. ESP8266 NodeMCU On-board LED

The LED is connected to a pull-down resistor, so when you send a HIGH signal the LED turns off. RST Pin

When the RST pin is pulled LOW, the ESP8266 resets. This is the same as pressing the on-board RESET button. ESP8266 NodeMCU On-board Reset button Report this ad GPIO0

When GPIO0 is pulled LOW, it sets the ESP8266 into bootloader mode. This is the same as pressing the on-board FLASH/BOOT button. ESP8266 NodeMCU GPIO 0 Flash boot button GPIO16

GPIO16 can be used to wake up the ESP8266 from deep sleep. To wake up the ESP8266 from deep sleep, GPIO16 should be connected to the RST pin. Learn how to put the ESP8266 into deep sleep mode: 

   ESP8266 Deep Sleep with Arduino IDE
   ESP8266 Deep Sleep with MicroPython

I2C

The ESP8266 doens’t have hardware I2C pins, but it can be implemented in software. So you can use any GPIOs as I2C. Usually, the following GPIOs are used as I2C pins: Report this ad 

   GPIO5: SCL
   GPIO4: SDA

SPI

The pins used as SPI in the ESP8266 are: 

   GPIO12: MOSI
   GPIO13: MISO
   GPIO14: SCLK
   GPIO15: CS

PWM Pins

ESP8266 allows software PWM in all I/O pins: GPIO0 to GPIO16. PWM signals on ESP8266 have 10-bit resolution. Learn how to use ESP8266 PWM pins: 

   ESP8266 PWM with Arduino IDE
   ESP8266 PWM with MicroPython

Interrupt Pins

The ESP8266 supports interrupts in any GPIO, except GPIO16.

AIS

Any sailors out there? AIS receivers are getting cheap, but they still cost anywhere from $200-$1000. You've already got a laptop and an RTL dongle. Want to use your laptop + RTL dongle as a chart plotter and AIS traffic receiver? Of course you do. Here's an example. And here's how to do it in Linux. 

   Install gnuradio.

   Install gr-ais:

   $ git clone https://github.com/bistromath/gr-ais.git
   $ cd gr-ais
   $ mkdir build
   $ cd build
   $ cmake ../
   $ make
   $ sudo make install
   $ sudo ldconfig

   Install OpenCPN:

   $ sudo add-apt-repository ppa:opencpn/opencpn
   $ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys C865EB40
   $ sudo apt-get update
   $ sudo apt-get install opencpn

   Add some charts to OpenCPN

   Install socat, a program to connect basically anything to anything else. We use it here to connect the text output of gr-ais to a virtual serial port:

   $ sudo apt-get install socat

   Make yourself a virtual serial port to read from:

   $ socat -d -d pipe:ais_pipe pty&

   socat will tell you the name of the pty it just created:

   2013/09/13 15:49:00 socat[24604] N PTY is /dev/pts/13

Add that virtual serial port (in this case, /dev/pts/13) to OpenCPN. It's in the settings menu. Baud rate doesn't matter. 

   Start gr-ais:

   $ ais_rx -dosmocom -g35 -r250e3 > ais_pipe

If you've got line of sight to some ships, you should be seeing traffic in OpenCPN. You'll want to play with the gain for best results. Keep in mind a couple of real-world caveats: first, you definitely need line of sight, or very near to it. Second, the RTL dongle has pretty lousy dynamic range, and 162MHz is pretty close to FM and TV. Not to mention if you happen to transmit on a marine VHF radio nearby it's going to blow the dongle out of the water. So using a filter on the RTL dongle is a really, really good idea. I found one cheap on eBay a few years back.

Have fun!
