Problem with LCD touch example

Former Member

Hi,

 

 

I tried couple of examples with STM32FDiscovery expansion Board and made USART and LCD 35T w/o touch example work.

But, LCD touch example kept giving me "calibration fail" message when I tried to calibrate the touch screen.

 

I'm using Keil uVision4 and used the project file in STM32Fxx_LCD_Example_Project/LCD_Touch/MDK-ARM

I set STM32F407VG as my target devcice and ST-Link Debugger as my debugger.

 

It compied and load without errors. LCD screen showed total five calibration points.

So, I touched each point with touch pen. But, "Calibration fail message" came out and it did calibration again.

 

Pleas help if anyone knows about this problem.

 

Thanks
