Re: emwin deployment

Thanks for your reply and we have downloaded the emwin sdk for lpc546xx and integrated the emwin libraries in our project currently we are facing the issue of in the GUI_init();So far we have not used the debugger in our project and we are using the uart for verifying the program flow .

as per program flow:

GUI_INIT----------------->LCD_INIT-------------->Hung or may be in hardfault exceptions.

We are using the external ram for storing the display buffer and gui buffer .Please go through the images i have attached for your reference.

We ae using tianma lcd part number TM104SDHG05
