Harmony LCC显示闪烁

大家好，我一直在做以下项目，-PIC32MX370F512L-HARMony V1_07_01-LCC-Graphics Display-PMP-Touch-UART(2)--i2c-timer-ADC-DMA。大部分时间都播放得很好，工作正常。e噪声或某种图形错误，我能给出的最佳描述是，在瞬间，正在绘制的屏幕的一部分将出现不同步，例如在屏幕上较低或更高，然后在下一次更新时，一切恢复正常。我试过，-从sy中移除所有外围设备所以它只是屏幕驱动器。-放慢主时钟-放慢屏幕的绘制速度-改变LCD脉冲和门廊设置-在LCDI的v-SYNC线上增加一个降噪帽，在运行期间仍然间歇地看到这个问题。有人经历过什么吗？类似的想法有如何识别问题（或解决方案：）？谢谢你的帮助

    HI all,

I have been putting together project with the following,
-PIC32MX370F512L
-Harmony V1_07_01
-- LCC
-- Graphics Display
-- PMP
-- Touch
-- UART (2)
-- i2c
-- Timer
-- ADC
-- DMA

For the most part it is all playing nice and working, the issue I have is a slight flicker on the LCD at odd times, it looks like noise or some sort of graphics error, the best description I can give is that for a split second a part of the screen being draw will appear out of sync e.g. lower or higher on the screen, and then on next update everything is back to normal.


I have tried,
- removing all the peripherals from the system so it is just the screen driver.
- slowing down the main clock
- slowing down the draw rate of the screen
- changing the LCD pulse & porch settings
- adding a noise reduction cap on the v-SYNC line of the LCD

I still see the issue intermittently during operation.

Has anyone experienced something similar of have an ideas how to identify the problem(or a solution :)) ?

thanks for any help
