STM32H743VIT Dual ADC Mode Regular Sequential Not Working for Me
I've been over and over RM0433 regarding how to set this mode up and I've never been able to get data from ADC2. ADC1 acts a bit oddly in that my reading says that 16 bit ADC results from both ADC1 and ADC2 are packed together in one uint32_t locatio...
Resolved! STM32N6 with built in flash?
Hi,Does anyone know if there is a chance for a new N6-device later this year having built in flash of at least 4MB?Our project is currently based on a one chip solution with a custom U5-board with built in FLASH/RAM of 4MB and a 5” Riverdi display. H...
