I've been wrestling with the datasheet for this 7" display. I checked all the jumpers and it is configured as 4-wire serial.
It seems like there is a typo in the datasheet, as they have two J2 connectors, one with 10 pins and the other with 40 pins (labeled Parallel/Serial Interface and CTP (capacitive touch panel) interface.
I want to double check if my assumptions are correct in the following connections to the display:
Use only the first 8 pins of the 40 pin connector
Pin Number (J2 AKA J3 on the device)
1 and 2 VSSGroundGND
3 and 4 VDDPower SupplyVCC
5 /SCS Serial Mode Chip Select (/CS), Low activeC/S
6 SDO 4-wire SPI Data Output (MISO)MISO
7 SDI 4-wire SPI Data Input (MOSI)MOSI
8 SCLK SPI Clock (SCLK)SCLK
I've attached the datasheet.
Thanks for you help.
