Can you explain me how to trigger NMI in STM32F103 MCU? I am wondering what is the purpose of this interrupt? And Why it is called interrupt because interrupts are trigger by peripheral.Can you show me an example how to trigger it?Thanks so much
I Need to collect the unique IDs of STM32F4 microcontrollers in a single script. so is it possible to connect 2 or more MCUs together and read their unique IDs together?Is it also possible to connect any external Hardware(like Bluetooth...) to STM32F...
@Imen DAHMEN Still looking here for a small-footprint solution in the stm32g4 line with hardware SPI flash (QuadSPI) handling. The WLCSP versions of the STM32G4x3 and STM32G4x4 lines might be viable. They are slated to be released in Q1 2020 (that ...
Hello guys, I'm using a STM32F439 Board and try to use FatFS together with a SDIO (eMMC). Additionally I try to read and write with DMA. Now I generated a very big text file and want to write this on the eMMC. The file will be transmitted via Etherne...
I am trying to setup the ADC channel on PA0. I have first set the pin mode to additional function. Then I have followed the examples provided in the reference manual. However, it doesn't turn on anything, either the calibration or the enable. It is n...
I want to use stm32f407gt with nextion touch screen. Display and stm will connect via to uart(Rx Tx pins). Stm work with 3.3V and nextion works with 5V. It will effect to communication ?
Hello all,I access SDMMC directly through the APIs: HAL_MMC_WriteBlocks() and HAL_MMC_ReadBlocks().Sometimes the access to SDMMC does not does not succeed with Timeout error.Can you please advise me?Thanks in advance.Yacob.
part number: STM32F779BII am using clock frequency 108 MHz ( not system clock , system clock is 216 MHZ)I don't want to use loopif not possible what is the maximum value i could set using timer
I want to configure timer of 10 millisecondsso for that according to calcuationUPDATE Frequency = TIMCLK / ((PSC+1) * (ARR+1)) My clock frequency is 108 MHzso when i set prescaler is 107 and ARR value is 9999 it should be updated frequcy is 100 H...
