Posted on January 12, 2018 at 13:55Hi,We are using a 216Mhz F7 (STM32F746NGH6) on a custom board to interface with an LCD (Winstar WF70GTIAGDNG0). We are having issues with the screen flickering, often the screen will display a flickering green blo...
Posted on November 07, 2016 at 13:32 Hello everyone, I'm trying to read an external SPI flash using DMA but I occasionally get an SPI overrun error. I've managed to track down the error: I get no overrun errors when I disable the LTDC IRQ. And more ...
Posted on January 12, 2018 at 09:28hi, I know the way to use HAL_FLASHEx_Erase() in my main loop and it works,erasing some flash areas.Now I want to use the HAL_FLASHEx_Erase_IT() , I have enabled from the cube the flash global interrupt,Do I have t...
Posted on July 12, 2017 at 19:29This isn't really a question - since I found a solution. It's an observation in case others encounter a similar problem.We purchased a new ST-LINK/V2 adapter recently and it shipped with firmware 'V2.J28.S6'.We use t...
