Hey!When I use images in TouchGFX, the color sequence seems different than in regular widgets. It only appears when images are stored on external flash (QSPI flash in my case), images stored on internal flash are fine.Below is an example: the top 3 s...

Hey!I'm having trouble using different regions of MCU's internal RAM. STM32H7 has 4 different RAM regions and I can't use them properly. So far I'm only able to move individual variables or functions into different than default regions by putting __a...

Hey!I'm trying to use ST-LINK/V2-1 from Nucleo to program and debug my board. I removed the jumpers from CN2 and connected CN4 to my board according to the manual:Problem occurs when I tie NRST of the CN4 to the STM32 on my board - in this case "DEV...

Hey!I initialized the TIM1 peripheral to output an complementary PWN signal on channel 2 (PB14) and tested it with an oscilloscope. Signal is present, everything's fine.Then after initialization of the SPI2 peripheral (PB13 & PB15) PWM signal is no l...

I'm completely lost in ADC working modes. And it happens EACH time I start a new project with internal ADC. So it ends up taking a lot of time to get the ADC do what I want.I need the following behaviour: 2 channels of single adc runs forever.By my r...

Hey!Sorry for reviving an old topic, I found the same behaviour. Chip is STM32G4. Here is my receive code:void usart_start_reception(void) { LL_DMA_DisableChannel(DMA1, LL_DMA_CHANNEL_1); // Do not Clear Channel global interrupt flag when the cha...

Thanks for the reply. The problem dissapeared, but I'm not sure how. I'm guessing this is due to a mismatch between the pixel format settings in CubeMX and TouchGFX here:

Rather silly question, but how to import both Date and Time widgets? I can only import one of them, the other one gives me an error that the files already exist when importing. Manually deleting existing files didn't help cause I got other errors

Well, I'd try disabling TouchGFX and fill the framebuffer with some simple pattern in RGB565 mode to make sure the display is showing what is expected and the hardware settings are ok.

Thanks for the reply. I moved FreeRTOS's heap to another region instead. That solved problem for now and was more straightforward (just in case https://forums.freertos.org/t/move-rtos-stack-and-heap-to-other-ram-region/17308/2 ). Yet I still don't kn...
