Building an IOT device connected to Internet via WiFi. How to reliably update the firmware? (If this is the wrong community group, please advise)Sample code or projects would be great. We are thinking: STM32L4xx FLASH set to dual bank mode.Both ...
Dear all,first I have to say that I am new to STM32F7 mirocontrollers, but I am not new to ARM-Cortex M4/M7 based controllers in general, nor the lwIP stack nor FreeRTOS.I have the following two problems:SMT32F767ZI + lwIP + FreeRTOS: I tried to buil...
I am working on testing libopencm3 based USB OTG FS stack for STM32F411/STM32F413. And OTG FS stack works fine to begin with without any issues. But, after a while it seems to lock-up waiting for transfer complete interrupt to fire on one of the IN e...
I ordered the STM32H757 EVAL expecting to have some example projects but when you download the H7 package there is nothing that is ready to go for the H757. The H7 package only has the H747.
