How to trigger a set number of ADC conversions with DMA using a hardware timer?

I'm working on STM32F767 with STM32CubeIDE using HAL (I don't have time to fully learn bare metal, I'm doing it in my spare time). I have TIM2 set up as a PWM on both CH1 and CH2 with a period of 200us and a duty cycle of 25% for CH1 and approx. 30%…

Cannot debug my STM32 CubeIDE project anymore, but code works without J-Link

I somehow have fallen in the state where I cannot start in debug mode my project in CubeIDE and J-Link. The code compiles, flash is written, but then instead of stopping on the first instruction in my main function in main.c, I get stuck in the…

TouchGFX widget visible on empty screen

I'm evaluating the TouchGFX tool additional to the STM32-Platform. Everything works "fine", like the interaction with some hardware resources of the STM32F746G-Discovery board, but there is another issue. I created a custom keyboard (as seen as in…

How do I show ADC values on my LCD screen using TouchGFX?

I would like to show adc values on my lcd screen on the stm32f746G - DISCO board. The main challenge comes from integrating the TouchGFX software. This generates the model, view, and presenter files necessary to output widgets and wildcards. I…

STM32F7-Is there a way to synchronize the output of two different timers in output compare mode?

My processor is an STM32F746ZGT6 and I wish to use TCD132DG, so I need to generate two synchronous clock pulses with different frequencies (One of them is 2 MHz and the other one is 500 KHz) so I used two different timers in output compare mode. The…

Consumption of SRAM for cortex-M3 and cortex-M7

I migrate from M3 to M7. M3 used STM32F103VE and has 64 KB of SRAM. The M7 is STM32F746ZG and it has 240KB of SRAM. I moved most of the M3 code to M7. Additional LWIP is being used for the Ethernet function in M7. But I found that heap memory was…

STM32: storing a map of addresses in an array

I'm trying to store a map of addresses in an array. The following code snippet works as expected on my STM32F767ZI, but compiles with a warning... intptr_t addressMap[2]; int* a=NULL; int* b=NULL; *a=10; *b=20; addressMap[0]=(intptr_t)…

Uart dma receive interrupt stops receiving data after several minutes

I have a project that I have used stm32f746g discovery board. It receives data with fixed size from Uart sequentially and to inform application about each data receive completed, dma callback is used (HAL_UART_RxCpltCallback function). It works fine…
