i have a device where i have MK22FX connected to a sdcard with the SDHC periferical and a LCD TFT. I have to read the data image from the sdcard and write this to the LCD that is interfaced with a 8bit parallel port. Every byte write to the TFT need to be validate with a rising edge of a GPIO of write. My question is if it is possible program the eDMA to control also this pin so all the data transfer is done only with the eDMA.
It is my first time that i want to use this periferical.
