Hi all! Help connect LCD ILI9341 to AMB25. According to the link on the connection page
https://www.amebaiot.com/en/amebad-arduino-spi-lcd-pm2-5/
The pinout of the controller board itself does not match. White screen when connected. Give me the correct diagram
I am using arduino 1.8.12 to work with the platform
I rummaged through everything in the libraries installed using the board manager. There is no mention of the rtl8720df chip. Rtl8720dn is available. It turns out there is no support for my chip?
Hi @Romson,
Can you show me your wiring connections? It might be that the wiring diagram is wrong on the website, we will fix it soon.
For now, I will write here what should be the connection for AMB25 to TFT SPI board.
TFT LCD to AMB25:
VCC - VCC
GND - GND
CS - PB21
RST - In arduino I defined this as 3. So this is PA12.
DC - In arduino I defined this as 2. So this is PA13.
MOSI - PB18
SCK - PB20
LED - VCC
MISO - PB19
You can refer to this diagram for the correct connection.
Please note that you can choose your GPIO pins on AMB25 for DC and Reset pins on TFT LCD Screen.
Thank you.
