STM32F373 ADC values are incorrect (between 1-20% from measured pin voltage)

My MCU is the STM32F373VCT6. I am performing a single scan of several ADC channels (DMA). The values returned are generally in the ballpark of where they are supposed to be but some values are very off from the measured pin values. I believe my confi...

HOw to set ExternalTrigConv for SDADC_HandleTypeDef structure of ADC's variable in my stm32xx MCU application?

I want to use two SDADC_HandleTypeDef variables in sigma-delta ADC-s differential mode triggered by timer TIM3 for example?

OCTOSPI memory mapped read failed in SPI MRAM

Hi!I have a serious problem trying to read in memory-mapped mode a SPI MRAM (MR20H40 from Everspin). I have configured my STM32L4R and I can WRITE in memory-mapped mode without problem, but while reading, I loose control of the MCU and I need to rese...

How to use a timer to stop another timer?

In the Reference Manual R0008, there is "Using one timer to start another timer" in Chapter 15.3.15. I want to know whether "use a timer to stop another timer" can be realized.Besides, I want to stop the timer in a rising edge, so the gated mode can'...

ADC+UART+DMA interrupt question

Hello, I am a beginner in embedded systems,I would like to build the following project on my STM32F102 bluepill board.I have configured TIM 2 timer for 1 sec period and it blinks the LED. (working)I also want to collect data through ADC and send it o...

STM32F7xx --> Undefined Reference to 'HAL_UART_Transmit'

Good afternoon,I recently started working with TouchGFX and encountered a problem while flashing the programm on my board STM32F746NGH6 (with the display: ETEM043005XDH6)After reading & understanding the code of the examples as well as building my ow...

I use STM32H742xI/G and I used the internal RAM to buffer for the display and buffer for keep data and the RAM is devided and i cant to extend the buffer of the keep data cause its passed from the memory part how i solve it?

UART/USART buffer is receiving garbage character after this sequence 1.Turning off power to RS232 2. Deinit Uart 3.Turning on power to RS232 4.Init Uart

UART buffer receives garbage character(first character) after power on reset to the module connected through UART? Is this expected?But while scoping RX pin,any character is not seen.

Unexpected performance when enabling cache with SRAM / external SDRAM.

I am using STM32F7508-DK and comparing the memory performance of its internal SRAM vs. the external SDRAM connected to FMC (starting from 0xC000_0000).When I turn on the cache, the performance behavior is unexpected. Especially, The external SDRAM is...
