Hi everyone,I have the STEVAL-IDP005V1 sensor board on which STM32F469AI MCU is present. I suspect that something is wrong with the D9 pin of MCU which is supposed to receive 3.3V from the power management unit on the board which I tested to be up an...
I have coded it both ways, so the hardware and software works except when switching to interrupt-driven receive. No interrupts happen, though I have checked and rechecked. The global NVIC can interrupt setting is there, and the enable. The CAN priori...
Hi,I am using STM32F103RFT6 64 pin package mcu. i am seeing can bit stuff error during CAN2 TX pin ( PB9) initialization. when mcu is in reset state this pin is in high state, the moment CANTX pin gets configure to Alternate function pushpul, Low s...
Hello,I'm working with SDIO to write data to a sd card and I'm using DMA. The basic process of my project is :1.Get 512 bytes data from an external ADC 2.Write it into a SD card3.RepeatI want to use the multiple block write mode, but everytime just s...
Hi,I Have two problem.first : using STM32F051R8Txcant use IO_TOUCHKEY2 at all !, have to assign IO2 to unused PIN and define new IO_TOUCHKEY.(if you need 3 touch you have to set 4 touch in CUBEMX case IO_TOUCHKEY2 doest respond!)second: why STM32F051...
Hi guys,The STM32F072C8 microprocessor has a total of 31 flash pages. Each page is 2 kb in size. Thus, the processor has 64 (2x32) kb flash memory. The interesting thing is that I can read / write on page 63. How is that possible?Thanks.
I've got NUCLEO-F429ZI board and I'm trying to write simple communication via SPI. I've generated code from CubeMX for SPI1, compiled it under Atollic TrueStudio and run. Unfortunately I cannot get SPI working. I mean I have no clock signal on SCK P...

Hi, I'm using STM32F103. I encountered a problem when using the system timer to generate a delay. The processor runs at 8MHz from reset, well I think, and I'm using that clock to generate a 1Ms delay. So, I've to load the SysTick LOAD register wit...
