Re: 8-bit parallel TFT driver for micropython ?

Thank you Robert, I already found and used some of your posts on this forum (mostly this one ). I will certainly find some inspiration in your code, but since I'm in a learning process, I am first trying to make my own amateur code draw something using the mem32 commands and starting from scratch. I...

Re: 8-bit parallel TFT driver for micropython ?

Update. I started coding an IL9341 TFT driver using parallel interface. I did not use the piece of code suggested by peter, but I started from the MCUFriend_kbv driver written in C for the arduino framework, since I had it running on my ESP32 board. This avoid any source of erors since I'm using the...

Re: 8-bit parallel TFT driver for micropython ?

@fdufnews : I saw this method in various posts while I was searching for a solution but I also understood that the use of this command (mem32 or mem8) was slowing the whole process. @peter : Thank you for the hints. I still do not really understand how to rewrite the "write" function. Do you mean I ...

Re: 8-bit parallel TFT driver for micropython ?

Thank you pythoncoder, I am far from being an expert in micropython (and coding in general) and i'm trying to understand the way your driver is working. I see you are using viper code and I guess the purpose is to achieve the pixel operations in a reduced time (I think if not it would take ages to g...

8-bit parallel TFT driver for micropython ?

Hi all, I've been searching for an available driver for my TFT screen screen Unfortunately, this device does not use SPI and I have no other choice to use the 8-bit parallel interface. The circuitpython displayio library seems to offer a parallel bus driver but I do not find anything equivalent for ...
