Using the PLL generated system clock frequency, it is possible to generate the same output frequency with many different pre-divider, Multiplier and post divider constant combinations. How can I determine combination is best for stability or lowest p...
To avoid the best accuracy when using the ADC it is advised to re-calibrate the ADC when environment temperature changes "too much"The ADC calibration can only be done when the ADC is disabled, so to re-calibrate the ADC has to be stopped, disabled, ...
Hi all,How loop back handled in hal layer if uwTick reach to the max limit HAL_MAX_DELAY=0xffffffff
Hi,i have been using F030C6 with 1 uart and make DMA works. but when i received a modem message( like AT+CPIN? e.g.) DMA stops 2 or more times. We can see the image below that i put one toogle pin to show when DMA interrupt occurs.my question is how ...
I have a test running on a Nucleo-H743ZI2 board which consist on a SPI master and a SPI slave sending data to each other. In particular, the master sends the slave the following sequence: {0xaaaaaaaa, 0x55555555} and the slave sends the master the op...
Hello thereI am trying to port a logic analyzer from STMF407: https://code.google.com/archive/p/logicdiscovery/to work on my STMH750B-DKI even found some pins I (think) I can use (PB4,PB6,PB7,PB15 (right arduino connector (D0,D1,D10,D11)I tried to po...

Hello,I am trying to transmit data to DAC using SPI DMA method on STM32h745 I tried all the methods that mentioned on forum. But i did not get the data on MOSI pin, when I use the polling method the data is successfully transmit .const uint16_t addr[...
