1st question: How many numbers will be saved in RAM?2nd question: Is it possible to get more accurate data by decreasing the ADC sampling rate.Thank you.P.S: I'm sorry, if this is a very simple question but I am a structural engineer and nobody is pe...
Hi, I have a problem configuring ADC1 on an STM32F429 to do a regular scan of a sequence of 4 channels without using DMA. The fourth channel is the internal temperature sensor. The third channel to be scanned always gives an overrun error (ADC_SR.OVR...
For SD memory card when there are errors in data transfer or do multiple block transfer, we need use CMD12 to abort the transfer, And there is function for SD card in HAL library, for example, there is 'SDMMC_CmdStopTransfer' in STM32H7's lib. But ho...
Hello,How do I retain a RAM section from bearing filled with '0' between resets.Suppose I have a pointer to 256 bytes buffer that I'd like to preserve between resets (as long as the power was not disconnected), could you please guide me, step by ste...
Hi,I would like to create an ADC driver for reading three channels, but I don't understand how I can read the single risult. I wrote a driver that read one channel (As you can see in attached file), What are the istructions for adding others channels...
hello, i am trying to connect a stm32F407 and stm32F072 via CAN bus. but i cnt manage to get it done. i successfully connected two F407 via CAN bus and i used the same code for both of the boards . both of them transmitt the data perfectally but none...

Solution: the ARPE bit was not set in the CR1. TIM1->CR1 |= 0x0080; solved the problem.Dear community,I am experiencing with an issue using TIM1 as a PWM timer. It all works fine, I can set the frequency and duty cycle with TIM1->ARR and TIM1->CCR1. ...
Have found great info on very flexible op amp with pga ability. The STM32H7 - OpAmp presentaion for example. Have found great info on ADC subsystem in the STM32H7 - ADC presentaion and in datasheets for specific STM32H7 part(s).Have seen the very w...
