Hi all! Help connect LCD ILI9341 to AMB25. According to the link on the connection page > **[SPI – Show PM2.5 Concentration on ILI9341 TFT LCD – Realtek IoT/Wi-Fi MCU...](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 ---

Hi @Romson, may I know which SDK version are you using? Thank you. ---

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 ![image](https://us1.discourse-cdn.com/flex016/uploads/ameba/original/2X/2/2675ca263ec05396fd31b12fdf6bb896f437c30c.jpeg) ![image](https://us1.discourse-cdn.com/flex016/uploads/ameba/original/2X/8/86a08f6657eeb8774fb67afc085cca0a6d1c5862.png) ---

You can refer to this diagram for the correct connection. ![image](https://us1.discourse-cdn.com/flex016/uploads/ameba/original/2X/c/ce71b821878df22fc7586184e66917fe2428ada6.jpeg) Please note that you can choose your GPIO pins on AMB25 for DC and Reset pins on TFT LCD Screen. Thank you. ---
