Hello, everyone.I looked at the difference between VOS0 and VOS3 through the datasheet to set the clock speed of STM32H753 to a suitable value.I am currently setting the system clock at 200 MHz and the FDCAN input clock at 50 MHz.When set to VOS3, th...
Hi all,I'm trying to figure out how to handle an interrupt. In particular I would like to handle an interrupt without using the HAL library. I want to handle the uart interrupt in reception: RXNEIE enabled: when the data is received an interrupt occo...
Hello,When trying to use ADC, I ran into a problem that I don't really understand.If I try to use ADC through the PA4 pin, the values read fine and are correct.However, when I try to use any of the other pins for ADC, none of them seem to read the co...
I'm using an STM32L476RG and making a LabView program to display sensor data. When a pin is set to HIGH I want to take a data sample and store it in an array in LabView. I am having trouble detecting the state of my 'sample' pin while continuously st...
Hi,UART stops transmitting (both IT and polling modes) after entering and exiting from STOP 2 mode. Although I'm renabling the UART when I'm exiting STOP 2 I don't see the data received on the other side.When I'm connected to MCU via JTAG everything ...
Hi, I have an STM32L072 micro. I need to count the transitions on two IO pins.I would like to do it while the MCU is in sleep mode and periodically wake to process the results.In this MCU there is only one LPTIMer . Is it possible to configure the ot...
The rest of the signals aren't easily accessible, but I've been trying to run the example camera project and I'm just seeing a blank white screen. After some debugging in the software, I found that it's getting hung up waiting for the first valid fra...
The board is needed for a small embedded project with low-power energy required. Thanks by advance
I am trying to use Tim6 with ADC and DMA2 to save 100 ADC values in a buffer. It seems to be working, DMA counter decreases and I get DMA interrupt, but only the first value in the array is stored, the rest are 0 (init values). Can someone help me un...
Hi everyoneI'm faced with another task using the STM32H755.. the goal is to output a square wave with one of the output compare channels of a general purpose timer (Timer3). The difficulty is, that the period varies with each period of the square wav...
