Effect of pull up without supplying power to MCU
As shown in above figure.The EXT/GPIO pin directly connected to MCU with pull up resistor (10K).So once the switch press the PMOSFET start switching supply to MCU.Please let me know the effect of voltage on EXT/GPIO pin without suppling power to MCU.
No trace SWO output on stm32H743VIT6. SWO printf not working
Hello.Hi Forum. I am new to the H743 line of processors and the first thing I tried is getting printf() output on the traceswo pin of my nucleo-H743ZI. What I have tried:1. The 'Everything out of the box' way:Use cubeMX to configure sys to async trac...
Resolved! ADC DMA values are refreshed only if other DMA peripheral are working
Hi everyone!I've got something strange with my ADCs (working on STM32H743). Everything was working until I realized that both of my ADC values are refreshed only if use other DMA peripheral. For example, it seems that sending SPI refresh the ADC, oth...
Power modes stm32H757
We develops the system that based on STM32H757 processorIn the working the application , I would compline to the three different running modes. 1. M7 - 480Mhz / M4 240Mhz --> full power mode (50% of application)2. M7 - 400MHz/ M4 200MHz --> run mode ...
Why my STM32 Nucleo 303RE board could not generate the correct SPI SCLK correctly with SPI mode 3?
I am using a Nucleo 303RE discovery board to try the SPI interface setting with STM CUBEMX, the setting is as below:SPI peed set: 4M/sSPI mode: 3Use HAL_SPI_Transmit API to send dataProblem: the SCLK clock shape is strange. The clock always has some...
FLASH data is not held
hey thereI have a STM32f030k6t6 which I wish to store data in its FLASH eeprom.the thing is sometimes data on certain addresses are cleared in startup! here is my codeHAL_FLASH_Unlock(); EE_Init();//eeprom initiallization EE_ReadVariable(ID_FLASH_ADD...
Hello everyone. I have three questions. flash memory write function.
1. Receive binary file from MCu1 to UART and save it to SD card (or EEPROM).2. Write the binary file stored in the SD card (or EEPROM) to the specific flash memory area of MCU2.3. Write the binary file stored in SD card (or EEPROM) to the specific ...
