Greetings all...

The ESP8266 is another WiFi capable board that's available and affordable. They're a bit slower and have less memory and fewer pins than the ESP32 but are fine for many WiFi applications, like a clock. Since I have a couple ESP8266 NodeMCU boards left over from another project, I thought I'd see if I could port Bruce's NTP clock code to run on one. It was pretty easy to get it going (an additional board definition, one line of code, and a few wiring changes) so if anyone's interested, let me know & I'll post the details.

Thanks to Bruce for sharing his clock projects. One can never have too many clocks. :)

OK...here it is...

Follow the steps in Bruce's write-up () with these changes:

- In the IDE, add this URL to the Additional Boards Manager URLS list in Preferences:

- In the Boards Manager install the esp8266 board

- Modify the User_Setup.h file in your TFT_eSPI library directory. I saved the existing file and created a new one with only these lines:

//TFT Defs for ESP8266
#define ILI9341_DRIVER
#define TFT_MOSI PIN_D7
#define TFT_MISO PIN_D6
#define TFT_SCLK PIN_D5
#define TOUCH_CS -1
#define TFT_CS PIN_D8
#define TFT_DC PIN_D3
#define TFT_RST -1
#define LOAD_GLCD
#define LOAD_FONT2
#define LOAD_FONT4
#define LOAD_FONT6
#define LOAD_FONT7
#define LOAD_FONT8
#define LOAD_GFXFF
#define SPI_FREQUENCY 40000000
#define SPI_READ_FREQUENCY 20000000
#define SPI_TOUCH_FREQUENCY 2500000

- Change the wiring from the display to the board:

Display pin 3 to D8 on the 8266
5 to D3
6 to D7
7 to D5
9 to D6

The other display pin connections are the same as in Bruce's write-up.


- In the source code, change the line

#include <WiFi.h>
to
#include <ESP8266WiFi.h>

- From the Tools menu, select 'ESP8266 Boards' and then select the board you're using, 'Generic ESP8266 Module' worked for me

- Compile and Upload

I hope this makes sense. If you have any questions, let me know & I'll try to help.

The three boards for $14 are the ones I used.
