Starting co-ordinate of screen is shifting

pavithrat — Tue, 14 Aug 2018 10:08:52 GMT

I am continuously reading the data and displaying it in 5 different text boxes with different colors. But the screen gets shifted from its original position after displaying it for 4-5 times. Please find attached snaps showing two different screens.

I am using i.MXRT1050 EVKB device with emwin version 5.38.

Please provide the suggestions to solve this problem.

Please try to use latest MCUXpresso SDK you can get here:

Also it is possible that you may run into issues with weak powering your board from the USB port of the PC. Please try to use another power source.

Hello Victor,

We tried using new SDK of version 2.4.0, but the problem still exists. We are using external 5V power supply as power source instead of USB port.
