I have an STM32G474RE, I have not used any HAL or LL libraries, I have only programmed using the registers, my issue is that I am only getting 0 on the output of the ADC, I read through the reference manual and still couldn't solve the problem. I hav...
I am using stm32g070rbt6 controller (32Mhz) and communicating with 16x2 LCD in 4-bit mode, Issue we are getting is in between the operation once in may be 2 to 3 hours, all of sudden LCD will get blank continuously, it'll come back to normal only aft...
Hello, I have a problem with RTC and UART reception using the DMA.I am currently working with the L476RG core board. The RTC clock is the LSE. The UART is configured in cyclic mode on the Rx PIN.I have done a simple data logging and could check that ...
Hi, i am trying to call timer interrupt handler using registers and the following is my code, but the problem is that the function is being not called, I see no output in the oscilloscope or live expression. First my DAC value is still 0, the counter...
Hello world,I'm developing a FW for STM32F107VCT6 which can change GPIO direction programmatically: there is a terminal command which can switch individually 7 pins* mapped on different ports between GPIO_MODE_OUTPUT_PP \ GPIO_MODE_INPUT.I'm wonderin...
Hi community.. Do you know in the repo examples where i can find a working example for uart for the evaluation board stm32f429 disc-1 ? Thanks
Hello everyone, I would like to use SDMMC1 with some low cost mcu with cortex m3 or m4 processor. Who have such experience, could you please share with your experience ? At moment I am using F746ZGT6 and it works great. I have decided to migrate to ...
All data received in normal mode is 0, but some correct data can be received in debug mode？ cubemx configurations are as follows：Part of the code is as follows:uint8_t pData[128] = {0x00}; HAL_SPI_Receive_DMA(&hspi1,pData,128); while(HAL_SPI_GetStat...
I use comparator(COMP7) on STM32F303VB as・Non-inverting input: PC1 (ADC)・Inverted input: DAC2 output・Comparator interrupt: rising/falling edge triggerI checked the COMP7OUT bit, but it seems that this bit is "comparator output at the time the bit is ...
