LCC Conventional V-sync refresh strategy not work
I'm interfacing PIC32MZ1024EFG with TFT LCD (LCC).
There is flicker on my screen (whole screen), and every object's edge are dance.I think it's because of using aggressive V-sync refresh strategy setting,However, when I change it to Conventional, DE, V-sync, H-sync and all PMD port not do anything.
Please give me some advice, why conventional mode is not work, or I suppose to look for another point.
- I've tried to float DE in aggressive mode, and I found that LCD don't use this signal linethat confused me, but v-sync and h-sync still be needed.
- I use REFCLKO1(PBCLK1) as LCD clock, thais not match with information I found by search engine and this forum.
MPLAB X IDE 4.0 with XC32 1.44
MPLAB Harmony 1.11
MCU : PIC32MZ1024EFG064 (SPLL from FRC at 100MHz)
LCD : Newhaven 5.0 800*480(WVGA)-No touch // (I config in Harmony as with PCAP)
LCC : Controller; Internal memory // 8-Bit color // DMA + PMP
* I've experienced in computer programming,but new to micro controller programming.Please help!
