Hy Seeed Studio Community ,
I bought a 2.8" TFT LCD on an SeeedStudio Shield ( V2.0 / ILI9341 ), and would like to know the reference PIN for this one .
I found , after couple of hours these pin names , but I don’t Find any information about Pin 0,1,2,3,8 and 9 .
And why are AREF and Vin Connected ? Are they used by the LCD ? ( I don’t see if they are connected on any signal on the PCB so I ask )
Is there anybody could Help me to find them ?
Here What I found :
Pin => Description ===================== 4 => TF_CS, SD card select input pin ( testing if card present or not ) 5 => TFT_CS, TFT chip select input pin 6 => TFT_D/C, TFT Data/Command control pin 7 => BACKLIGHT, TFT backlight control pin 10 => SPI chip select 11 => SPI data pin 12 => SPI data pin 13 => SPI serial clock pin A0 => Touch Screen Y- input pin. A1 => Touch Screen X- input pin. A2 => Touch Screen Y+ input pin. A3 => Touch Screen X+ input pin.
Thanks in advance .
