Re: GTT70 TTL Tx / Rx flip
Hello Sean,
Please check Return Message for command 254 55 in the manual.
37645 is the correct module number for the GTT70A-TPC
37636 is for the TPR model; sorry the manual only lists the TPR models

Re: Linux load bitmap
Hi Michael, Did you try to turn flow control off on the GTT? Please check that the autoexec file includes the command to turn the flow control off. Or, if you have left the GTT default (flow control on), and turned the flow control on on your Linux host, did you connect the CTS/RTS lines to the GTT?...

Re: GTT70 TTL Tx / Rx flip
Hi Sean,
Please try simpler commands for now: 254 0 or 254 55 as you mentioned earlier.
I think you are not giving the write and read scratch pad commands the right parameters.
I wonder if you are taking advantage of the driver code we provide:
Firmware\Client\gttclient

Re: Linux load bitmap
Hello Michael, Thank you for posting on the forum. I see that you have flow control off on your port settings. Please note that the GTT has default flow control on. You can choose to have it off via the GTT Designer project. Can you also please try a simple query command like gtt_get_protocol_versio...

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?

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: 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 ...
