I’ve been playing with the STM32F746 Discovery using System Workbench for a while and decided to purchase a Waveshare OPEN746I-C kit http://www.waveshare.com/product/mcu-tools/stm32/open/open746i-c-package-a.htm as I wanted a bigger touchscreen and access to more of the pins.

I’ve got most of the example code Waveshare supply (intended for keil) working correctly http://www.waveshare.com/wiki/Open746I-C in System Workbench by using CubeMX and copying across the files from the example and adding the include paths in the C/C++ Build settings.

Everthing seems to work fine and I don’t get any errors or warnings when compiling however in the examples with the touchscreen (Touch and STemWin) the touchscreen doesn’t work.

I then used Keil to compile the example and the touchscreen works fine, I’ve been through the code and cannot see whats wrong and the projects build without error and run ok apart from the lack of touchscreen.

Any suggestions as to where I’m going wrong?

Thanks in advance
