DISCO-F746NG LCD Flicker Problem
I have a problem with LCD flicker on the DISCO-F746NG board. The LCD horizontal flicker episodes last 67 seconds, commence 27 minutes after reset then occur at 71 minutes intervals. Here is a poor quality picture from the motion-sensitive security camera that we used to capture these events over a day.
Forum posts from other sites reporting the same problem suggested issues with the use of floats or FreeRTOS but these are not applicable to our application. mbed 2 and mbed-os give the same result. I am using unmodified ST BSP and LCD libraries and those from here https://os.mbed.com/users/MikamiUitOpen/code/F746_GUI/ .
Any advice would be really appreciated.
