HelloI have a const variable located in the internal flash memory. When I directly access this variable in flash, the read operation returns always 0 (even when the content of that location in flash is not 0). When I change the code to first copy the...
I would like to trigger ADC conversions using a timer so that I can get the time associated with each sample. This is so that I can plot voltage vs time like an oscilloscope.According to the datasheet, it seems like the maximum external ADC trigger i...
I am using SPI1 as a Master full duplex , and checking in the Nucleo 429 zi PA5 ------> SPI1_SCKThere is no clock , I using a scope and testing PA5 pin on the Nucleo 429 zi I attach the code , its very short code Here is the link to the pin descr...
Hello everyone,I am currently trying to get the ADC on the STM32H745ZIQ to work like it should according to the AN *Getting started with the STM32H7 Series MCU 16-bit ADC - Application note.On page 3 the spectrum is shown along with the measurement s...

HI thereI am do a continues read an of ADC a parallel binary data https://datasheets.maximintegrated.com/en/ds/MAX2771.pdf at the speed from 4-16MSPS with nucleo-H743ZI2. The binary data is sent through 2 ADCs where each has a specific channel I(I0,I...
NUCLEO-H743ZI2 board SAI A1 16bit data, 2 slot as slave.codec TLV320AIC23BIPW , clock 12MHz, I2S mode 46.8KHz BCLK=3MHz.I can read the samples of the left channel correctly. I can't read right channel samples.static void MX_SAI1_Init(void){ /* USER C...
HelloI'm using timers with DMA and I was asking myself of the use of having different clocks for timer clock and timer bus. For example timer 2 has a 90 MHz clock and a 45 Mhz bus. What would be the limitations of the bus?
