We have STM32F405RGT6 and we want to implement DAC through DMA.We used an example for STM32F429ZI-NucleoHere is an actual code where we have an underrun the error and we need help to clarify reason and find a solution, thanks!: #include "main.h" #i...
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...
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...
Hi,I am using an STM32H7RS MCU (NUCLEO-H7S3L8) and I need to use both USB HS Device and Ethernet MAC.For Ethernet MAC I will only need to use MDIO interface, so I don't think I need a stack for it but please correct me if I am wrong.The MX_ETH_Init c...
