"Hello, while examining the STM32L412C8 microcontroller, I came across the term VDD12. What is VDD12, and can I use the peripherals without making the VDD12 connection? In other words, is it mandatory to make the VDD12 connection?"
I have read previous posts ,,,I set up dma to read adc ,Although dma's destination address is allocated from AXI RAM, dma does not work when d cache is active.Can anyone share detailed information or a sample code about this?
hello , I use spi and ı use slave mod spi. When I send a frequency of 500khz or more as a clock so data is shifting or I recieve wrong data but I send a frequency less than 500 khz I recieve true data. what is the reason of this.( use stm32h743z...
for example I send 0xC1BA(1100 0001 1011 1010) and I check pin with oscilloscope I see 0x8375(1000 0011 1011 0101), data is 1 bit shift left but if frequency is less than 500 khz no problem.
yes i did what you said and tried adc in continuous mode with dma for 100 samples. I really got the expected results.When I ran it for a single sample, I saw that it was slow again. What is the reason for this?
