Is there any possibility to connect a display to the A24 panel? I do not use the gsm connection, nor the K-thermometers.
there two way:
1. use by serial display, you can connect to GSM interface's RXD,TXD pins.
2. use SSD1306 i2c bus display, just connect to i2c SDA and SCL pins.
In 2. option i plug paralell the display to SDA-A:GPIO16 SCL-A:GPIO5 ?
And what about SPI bus for MAX31855 SCK: GPIO14 MISO: GPIO12 ?
