Re: GTT70 TTL Tx / Rx flip
Hello Sean, Good to hear that you get ACKs from the display now. In order to get the GTT70A to reply via I2C, you will need to set the communication channel to I2C. You may please check command 254 5 from the manual . With I2C, all communication transactions are master initiated. To read back replie...

Re: GTT70 TTL Tx / Rx flip
Hello Sean,
It looks like you are addressing the GTT70A with 0xA0. Can you please try 0x50?
Thanks,

Re: GTT70 TTL Tx / Rx flip
Hello Sean, Thank you for posting on the forum. I think you have done pretty good troubleshooting. My first thought was for turning off flow control which you have done. Please make sure though that command sent is 254 58 0. If this still does not work, I think the TX line may have been damaged as y...

Re: What does the "Command" in Set and Save Data Lock do?
Hello madz,
I apologize for not getting back right away.
Yes, that is correct, a check for 202 245 or 203 245 as command parameters is done.

Re: Screen updates
Hello koyocik88, Thank you for posting on the forum. The important thing to note on macros: The macro feature is only suitable for use with display lists and not as part of a co-processor list, as the co-processor would regard the Macro command parameters as values rather than pointers to the REG_MA...

Re: HTT50G Flickering under Windows and Linux
Update: Flickering was rectified by powering the HTT50G separately using the barrel jack (separate power source, not from USB).

Re: What does the "Command" in Set and Save Data Lock do?
Hello Madz, Thank you for posting on the forum. Locking Command means it will ignore all commands; ie data that starts with the command prefix 254. But It will only toss the data after 254. If the command has parameters, say for example contrast command which has 1 parameter, the display will start ...

Re: Connect ESP32-S3 to the graphics chip BT815Q via SPI
Hello Robert, Unfortunately the data you shared do not seem to make sense. wr32 (REG_FREQUENCY + RAM_REG) I am expecting 0x30 0x20 0x0C 0x00 on MISO and if you are not actually trying to read, I do not think you should be interpreting the MISO line. You might want to check with EVE forum. I see that...

Re: GTT29A keypad illumination isn't working
Hello Jamesh,
The keypad on the GTT29A is default on; perhaps the LEDs on the keypad are broken?
Do you have the serial number on your GTT29A?
Thank you,
Raquel

Re: The schematics of "EVE4x-40G-IPS" are required.
Hello, Thank you for posting on the forum. I wonder if you have a serial number on your EVE4x-40G-IPS you can share so I can check the model? If you have a VS model you can power it with 5-15V, otherwise it will take 3.3V only. For now if you please check out this manual for the 20 pin FFC pin out. ...
