LTDC branch, program freezes when changing the resolution

Post by epikao »

Hello,

I have a question to the following branch / LTDC library part:
https://github.com/fpistm/Arduino_Core_ ... /libraries

When I change 480 and 272 to another value as for example 1024 and 600 pixel, the program freezes immediately (directly after plugging in)
What is the best way to solve this? I am grateful for any hint.

Thank you

Code: Select all

constexpr LTDCSettings LTDC_F746_ROKOTECH = {
    .width = 480,
    .height = 272,
    .horizontalSync = 41,
    .horizontalFrontPorch = 32,
    .horizontalBackPorch = 13,
    .verticalSync = 10,
    .verticalFrontPorch = 2,
    .verticalBackPorch = 10,
};

class LTDC_F746_Discovery : public LTDCClass<480, 272> {
    public:
    LTDC_F746_Discovery(): LTDCClass(LTDC_F746_ROKOTECH) {

I can pay 100 USD or more for the person who gives me the decisive hint ?
