In my code i first setup the sim7600 using blocking mode and later switch to dma. But in blocking mode I'm having trouble receiving data over uart. Using a nucleo it sometimes works very reliably and other times doesn't work at all or it only receive...
I refuse to purchase a $40 chip for over $400 dollars so will not purchase on current market. I based an entire product line on the STM32H757 and now I cannot buy them so the real question is, should I move to a different processor?

Hi,I found this in datasheet But we config SDRAM at 120MHz, because we are running at 480MHz.(480MHz / 2 / 2 = 120MHz).I am thinking the datasheet is for STM32H7xx 400MHz, because when I config SDRAM at 120MHz, the system works fine without issue.Doe...
Hello, I need some help. I have problem about CAN bus. I connect the wire to the header pin. It swaps between CANH and CANL. Can STM32 force CAN_TX pin to CAN_RX pin and CAN_RX pin to CAN_TX pin? If not, do you have another solution?In my case, I can...
