Port to STM32F407

[RedCatN1]

Hello, I’m trying to port your project to the STM32F407 processor and ili9488 480x320 display, the NanoVNA-F project, which is based on FreeRTOS, was taken as the basis. It seems that everything works out, there are only 2 problems with rendering left, the first problem is the is_markmap function, for some reason, if this check is turned on during drawing, the lattice is not completely drawn and the second problem after setting Start / Stop a second time the on-screen keyboard does not appear and automatic redrawing occurs , could you explain the algorithm a little? Thanks. Sorry for my English. I'm from Uzbekistan. Regards, Andrew, UK8LCJ.
