I am trying to build an iap that reads a .bin file from a uSD card and loads it into the flash memory, but something is happening with the erase function. If i run this bootloader and the flash is empty everything works just fine. However, if the fla...
I have a STM32G071 nucleo and want to generate an arbitrary waveform on PA0 via TIM2-CH1.I am using the HAL_TIM_DMABurst_MultiWriteStart API: it should do bursts of 3 writes to multiple registers (ARR and CCR1).Problem is, the DMA only updates the AR...
I'm interested in motor speed control. When reading the documentation on the timer modules, it talked about having the counter value saved using a different timer or DMA. What I am wondering is can I read the value manually via an ISR and reset it to...
HiI created my own board with a STM32F411RE microcontroller. I can program it normally with a ST-Link v2 probe, the program works correctly.But from time to time when I disconnect this probe the board stops working. Can someone explain me why?On my c...
hello , ı use stm32h750vb I m trying work spı,I set the spi as master mode, when does the master send the first clock pulse.i'm not doing any clock observation at all when i just check clock output
hello , ı use stm32h750vb I m trying work spı,I'm trying to raise the miso pin at the beginning of the dialog, I'm wondering how you can do it.
I am using the STM32L072CBT and wish to use PB15 as PWM output. I have created the project in CubeMx but selecting PB15 offers no timer channels at all. I have double checked the data sheet which shows PB15 with AF1 as TIM15_CH2. I have created a new...
I'm using a STM32F469 Discovery board, i was using a board with B-01 revision, my software works just fine, now i want to use the same board but with B-03 revision but for some reason the same software doesn't work on this board.Note: B-01 rev flashe...
Hello, I am using STM32G030F6Px, it has 32 KB flash memory and I need free space to save data in flash, also it needs to have bootloader. That's why I decided to use bare metal code instead of HAL library, of course I did this by examining HAL librar...
I am working with the STM32F446 microcontroller and compiling with Eclipse/GCC. Short version: I have two functions, main1(int argc, char* argv[]) and main2(int argc, char* argv[]) and I want to be able to goto back and forth between the two many tim...
