BuyDisplay (EastRising) Display ER-TFTM070-5V4 connections

John Owens K1JO All Messages By This Member #33810 Edited 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. ER-TFTM070-5V4_Datasheet.pdf ER-TFTM070-5V4_Datasheet.pdf

K9HZ All Messages By This Member #33812 开云体育 The correct connector to use for interface is the 40 PIN connector.?? I cut pins 11 and 12 off the connector and then a 10 pin header fits on the first 10 pins of the 40 pins perfectly.? Make sure you wire them properly to match the display connector or you will blow out the RA 8875 Controller chip on the display board. ? ? Dr. William J.

John Owens K1JO All Messages By This Member #33814 Thanks Bill. Yeah, I just cut off pins 11 and 12 so that a 10 pin connector will fit. It looks like the T-41 display pinout is a mirror image of what it needs on the Display, so I think I can wire the cable normally but then plug in pin 1-2 of the cable into 9-10 of the display (both unused) I'll double check, to make sure I'm not thinking crazy.
