    vgopaitsa I'm really glad it's working for you! If you want to make a nice GUI, I can suggest the following: Ring gauge - this is fairly easy to adapt to your current display library, and looks cool with little...

    By the way, I plug into the OBD port, not directly to any of the available busses in the car. I was after true P&P :D

    As Tony mentioned, UDS is not easy to understand and it's not documented anywhere but it's got more enhanced data than standard OBD2 PIDs - that's why can sniffing individual PID's is the best option IMO to find what...

    Yep, that's exactly what was suggested to me. I applied that to both the image and to all of my font files. I went from 126% usage of RAM down to 60%! It was also suggested that I could move some heavy functions into...

    I have experience with the MQB platform, but as your Jetta is on the PQ35 platform, I can't provide you with my request response sample as it's not the same. What kind of data do you want to display on your tft? ...

    Thanks!! I opened a thread over at the LVGL forum and after some help there we realised the images I was loading was being stored in RAM and not in Flash, so I am making a modification to change that - which should...

    I've tried searching the forum on this specific question for the last 40 mins but didn't come to an answer... I was wondering if it would be possible to allocate the 8Mb PSRAM chip to the system RAM without having to...

    I FINALLY got to testing the buydisplay ILI9488 on the T4.1 with external PSRAM. Unfortunately, it does not work well at all using external PSRAM. It seem to update extremely slow when uncommenting #define...

    I second this! ^^^ would like to see higher res displays driven directly by the chip - seen some beautiful things on the development boards with LVGL and Qt.

    Sounds interesting! I have some bare ILI9488 displays that can be driven either SPI, DBI or RGB(as you plan to) that I can also test on. Happy to try it out once you have something built up

    Kurt I was under the impression that only FLEXIO3 could be used as all it's GPIO's on the same port register. But, if we can combine FLEXIO1 & FLEXIO2 with DMA that could be ideal, no? I saw this video of a T3.6...

    Has anyone else tried the 16bit parallel interface with the T4.1? It would be interesting to see how it performs against the SPI-DMA libraries by Kurt.

    Rezo replied to a thread Qt for MCUs in General Discussion
    Im already using those libraries on the T4x, have been for the last 6 months. But they are simply an API to send commands to the display to draw lines circles strings etc. Qt is the layer that handles the GUI, similar...

    1. For my needs, ILI9488 or HX8357 both supporting 16bit (or 18 bit) color depth and a resolution of 480x320 2. I have no idea, I have not gotten into the working parts of Qt, this is why I responded to the thread :)...

    Rezo replied to a thread Qt for MCUs in General Discussion
    I thought I would revive this thread as I just came across Qt for MCUs and now that we have the T4.1 with the option to expand both SDRAM and Flash - might allow one to utilize the Qt framework But I suspect that Qt...

    Amazing! I remember the early versions of MegaSquirt - gosh that was like 13 years ago. But the entire ECU board and housing looks top notch! Perhaps you can also add in some form of dashboard display to work with this
