Hi,

 

Is there sample code available for the following setup ?

 

eGui

MQX 3.8.1

CodeWarrior 10.2

TWR-K70 & TWR-LCD-RGB (rev B)

 

This would really help me!

 

I tried to port K70_eGUI_PE sample code to MQX, but with no success so far. (see details and problem below)

 

 

I have a bare metal demo K70_eGUI_PE.

This is  eGui + PE+ CW10.2 for the TWR-K70 en TWR-RGB-LCD. It works ok.

 

I copied all D4D code into a new MQX 3.8.1 demo application. Compiling is ok, but it crashes in  d4dlcdhw_k70_lcdc.c when setting the DMA Burst mode register.

  //Set background plane DMA to burst mode

  LCDC_LDCR &= ~(LCDC_LDCR_BURST_MASK);

 

d4d_user_cfg.h :

#define D4D_LLD_LCD d4dlcd_frame_buffer   // the name of low level driver descriptor structure

#define D4D_LLD_LCD_HW d4dlcdhw_k70_lcdc

#define D4D_LLD_TCH  d4dtch_cr_touch

 

I don't get further than :

Main.c :

D4D_Init((D4D_SCREEN*)&screen_Demo);  

d4dlcdhw_k70_lcdc.c -> LCDC_LDCR &= ~(LCDC_LDCR_BURST_MASK);    // STOPS HERE !!

 


Any help/idea's are welcome!

 

Many thanks in advance

 

Regards,

Michris
