LCD touch-screen on MK53DN512CMD10 set d4dtchhw_kinetis_adc_cfg and d4dlcdhw_gpio8080_8b_cfg

Hello,

I have tried to use a touch screen with a microcontroller MK53DN512CMD10, i'm trying to configure the hardware. It's connected as shown on the table.

TOUCH-SCREEN	MICROCONTROLLER PIN NAME
CS	PTC9
RST	PTC10
D/C	PTC11
WR	PTC12
RD	PTC13
DB0	PTC0
DB1	PTC1
DB2	PTC2
DB3	PTC3
DB4	PTC4
DB5	PTC5
DB6	PTC6
DB7	PTC7
Y+	ADC1_DM1/ OP1_DM0
Y-	PGA1_DP/ ADC1_DP0/ ADC0_DP3
X+	PGA1_DM/ ADC1_DM0/ ADC0_DM3
X-	ADC1_SE16/ OP1_OUT/ CMP2_IN2/ ADC0_SE22/ OP0_DP2/ OP1_DP2
LED-A	DAC0_OUT/ CMP1_IN3/ ADC0_SE23/ OP0_DP4/ OP1_DP4

And i maded this configuration so far:

#define D4DLCD_CS

9

#define D4DLCD_DC

11

#define D4DLCD_WR	12	// WRITECLOCK
//#define D4DLCD_WR_PORT	PTED	// WRITECLOCK

#define D4DLCD_RD	13	// READCLOCK
//#define D4DLCD_RD_PORT	PTED	// READCLOCK
//#define D4DLCD_RD_DDR	PTEDD	// READCLOCK

#define D4DLCD_RESET

	OUTPUT(C,7);\
	OUTPUT_ALL(C)

#endif /* __D4DLCDHW_GPIO8080_8B_CFG_H */

I try to run my code and got stuck on the next function at the d4dlcdhw_common.c file:

static void Cpu_Delay100US(unsigned short us100)

   {

    unsigned int i;

    while((us100--)){

      for(i=0; i < (MCU_BUS_CYCLES_100US/10); i++)

        {// 10 cycles delay

          asm("NOP");

          asm("NOP");

          asm("NOP");

        }

    }

  }

¿Is my configuration correct?

¿how do i configure the adc for the touch-screen?

¿how do i use the DAC output for the backlight ?

I will apreciate a lot your help !!!!!

Hello Alberto,

Which touchscreen are you using? Are you migrating from another project?

Best regards,

Earl.

Hi Earl,

Thanks for your answer. I'm using a touchscreen model NHD-1.8-128160EF-CTXI-T and yes i'm migrating form another project.

I left the link of the datasheet below.

Regards

Alberto

Hello Alberto,

I saw that there is another thread with the same question D4D library troubles using a touch-screen LCD / MK53DN512CMD10 microcontroller, I will be answering there, is that OK?

Best regards,

Earl.

OK,thank you.
