I have a Teensy 4.x that uses the IMXRT1062 chip and I have successfully gotten FlexIO to work driving an LCD display via MPU interface (8080) with DMA transfers.
I did some reading on the 1060 datasheet and noticed that in the eLCDIF chapter, it states the LCD controller can support the MPU mode as well
Is there a code example for driving a display in MPU mode with the eLCDIF? Or application note? And if it really can support the MPU mode, which of the LCD pins get mapped to LCD_RS, LCD_WR, LCD_RD etc?
@CarlosGarabito thanks for the response.
I took a look into the examples online and saw there is only elcdif-rgb (dotclk mode).
I'm looking for the MPU mode which would work similar to FlexIO 8080 emulation
@CarlosGarabito as mentioned, I have FlexIO and DMA working to drive a display.
I want to use the eLCDIF and PXP together, and in order to do that I need to put the LCDIF into MPU mode; LCDIF_CTRL[MASTER] = 0;
But I need to understand the pin/signal mapping eg what pin is WR, RD, CS, D/C
@Dogbone yes, the documentation does leave alot of room for imagination.
I and a few forum members over at PJRC found this out the hard way with FlexIO when figured out there are only 4 shifter buffers available, while the documentation states that there are 8.
Hoping to get some positive response on my question above
