Hi!I am having problems reading accurate values using the STM32H7B0 CPU. I have identical boards with STM32H7A3 and STM32H7B0 CPUs and the results from the B0 boards are off by a lot. I have also tried to run the ADC in 12 vs 16 bit mode and the scal...
I am using STM32F407G Discovery1 board. I'm printing Hello world and I want to debug to see the string. I do debug configuration: I set debug probe ST-LINK GDB server, i check SWD like interface and enable SWV with core clock 16MHz but still I don't ...
Hi,I am trying to have a DMA move one unit of data every time the timer finishes it's counting period. The DMA would be circular so it would continually do this. I am going to be moving from a buffer to the CCR register of a pwm output. I saw a HA...
I have an STM32L100C-DISCO board (MB110B Rev. B) and I want to install the LSE crystal, which is not populated by default. I consulted the schematic in the UM1656 "user manual for the 32L100CDISCOVERY discovery kit". Crystal X3 has a part number of...
test code as below:#include <rtthread.h> #include <rthw.h> #define CPU_USAGE_CALC_TICK 100 #define CPU_USAGE_LOOP 100 static rt_uint8_t cpu_usage_major = 0, cpu_usage_minor= 0; static rt_uint32_t total_count = 0; static rt_uint32_t _c...
Dear All,I am trying to develop a code for STM32H742VGT revision V. ADC1 and ADC2 work in regular simultaneous mode and they are set to convert 6 channels. All the settings are exactly same to have same sampling and conversion time. Of course, ADC1 a...
I´m using the SPI1 via the alternative pins PB3-PB5 and I'm experiencing various issues. I have previously used the STM32F722 with somehow same CubeIDE setup and code and that works perfectly.I have made a simple test application that only sends one ...
Hey Folks.So, I have the H757I-Eval Board that I got as a gift, and given that I'd like to try some stuff and even follow some tutorials, I miss the exposition of the PINs. Reading TN1238 which talks about a fan-out expansion board, it says "The prin...
I am making this call: if(HAL_SPI_Receive_DMA(&hspi3, &aRecvBuffer[0],3)!= HAL_OK)inside an external GPIO interrupt handler that gets called every 20 us. It is used to read data from an external ADC. I noticed that this dma transfer works well only ...
