Hi, This may be an easy thing to answer, but I haven't had much experience. I have a JSON message that I'm sending down to my F446RE board.I am using the HAL_UART_RxCpltCallback function, this works great, however, for this to work I need to know the...
Hi,I have a flash corruption trouble with stm32f103 mcu. While i was reading topics, i have found that a reset generator must be used on system for avoiding flash data corruptions. My device has lots of parameters on stm32 flash, sometimes those data...
Hi friends,I think my question will repetitive for you guys (in stm-forum) . Actually sorry for that. I have driven a bldc motor with square wave commutation. Which is basically a simple and easy technique. And i have controlled the bldc motor (in s...
Now the project uses STM32L431RC external nor flash to save the data. I want to replace STM32L431RB external QSPI flash, which can reduce the cost, but the program byte is too large, so it needs to be put into the QSPI device to run. QSPI flash is di...
Hi there!I have this MCU and i see as an alternate function 14 it can configure PA1 as TIMx_IC2.I cannot find in the documentation or block diagrams the meaning of this function? is it like a TIM_Channel? or like TIMx_ETR?Thanks!
Hi everyone! new around here.. i am taking an online course about DMA controller.At the very first lesson they teach how to check routing using DMA BUS MATRIX.The problem is that i cannot find of any of my two board that uses STM32L100 or STM32F103.A...
I'm using the STM32L152 processor. I just noticed that on a reset the value at IVT slot 0, which should be the MSP value, doesn't get put into the MSP. I see another value there on a reset. I added "ldr sp, =_estack" at the start of Reset_Handler, an...
Hi Everyone. I'm modifying a the example project "ADC_RegularConversion_DMA" for the STM32F4-Discovery board.I now want it to work via TIM2 trigger. I would like TIM2 to trigger the ADC, and then the DMA to transfer the ADC result to a buffer.The pro...
Hello,I am trying to add s RAM section at the end of the RAM to savesome data (states) between warm reboots, when the watchdog kicks due somewiring problems (i2c).I changed the ld file as:I reduced the stack -2kI reduced ram -2kI created a RAMAUX and...
