Re: Attempting to get SSD1963 working with a Nucleo-F767ZI (144)

Hi all, Jean-Marc the author of the library for GxTFT has been very helpful and corrected the timing and managed to get FMC to work with the Nucleo 144, including changing the FMC address region to bypass DCache GxTFT discussion Version 2.1.3 of library GxTFT is available. - added FSMC/FMC support f...

Re: Attempting to get SSD1963 working with a Nucleo-F767ZI (144)

fpiSTM Okay that's great, I'm going to be using the registers anyway but just wanted to double check. I have physically disconnected the STlink serial from the board via solder bridge SB5 & SB6 on the Nucleo board but I was wondering whether I need to set any build_flags to prevent enabling Ser...

Re: Attempting to get SSD1963 working with a Nucleo-F767ZI (144)

fpiSTM I managed to test bitbashing with using just pinMode on the Nucleo-F767ZI but I had to use the Zio Connectors (uno equivalent pins) and get something to display. The performance was poor so next I will have to work on the registers and make sure the timing is correct to spec to speed things ...

Re: Attempting to get SSD1963 working with a Nucleo-F767ZI (144)

I think I was slightly doing the cache disabling wrong on PlatformIO. In the configuration file (platformio.ini) you set 'build_flags' build_flags = -DI_CACHE_DISABLED -DD_CACHE_DISABLED this then automatically updates the defines in c_cpp_properties.json "defines": [ "PLATFORMIO=5000...

Re: Attempting to get SSD1963 working with a Nucleo-F767ZI (144)

Okay, it doesn't seem to have made a difference with disabling the DCache & ICache - assuming that I have managed to disable them. I believe it is disabling them in the json as I put a made up definition to see whether PIO would throw a message and it did moan whereas it did not complain when I ...

Re: Attempting to get SSD1963 working with a Nucleo-F767ZI (144)

Oh sorry, misunderstood the build_opt.h.

I will give it a go with the JSON as noticed "HAL_UART_MODULE_ENABLED" is defined in there.

Thanks for your help.

Re: Attempting to get SSD1963 working with a Nucleo-F767ZI (144)

Thanks, how would I go about implementing that with PlatformIO IDE. I created build_opt.h as per https://github.com/stm32duino/wiki/wiki/Customize-build-options-using-build_opt.h#how-to-customize-build-options and placed it in in the root of src but it doesn't look like it is disabling Dcache and Ic...

Attempting to get SSD1963 working with a Nucleo-F767ZI (144)

I've created a pull request on github for modifying the GxTFT IO class for Nucleo_144. https://github.com/RGarrett93/GxTFT/pull/1 Using ZinggJM library GxTFT on a F4 using FSMC, I managed to run LVGL with a 7" SSD1963 display. https://github.com/ZinggJM/GxTFT I now want to attempt to getting th...
