ILI9163 dosen't seem to recieve data.

[msalko]

Hi. I'm working on a project with ili9163 lcd and tiny gecko.
the display works, but it won't recieve image data i send in.

do you guys know what might be the issue?

here is my code:

Code: [Select]

void LCD_init(void)
{
// enable peripheral and spi clock
CMU_ClockEnable(cmuClock_GPIO,1);
CMU_ClockEnable(cmuClock_USART1,1);

// set maximal speed
CMU_ClockDivSet(cmuClock_HFPER,1);


GPIO_PinModeSet(LCD_CS_PORT, LCD_CS_PIN, gpioModePushPull, 1);
GPIO_PinModeSet(LCD_CLK_PORT, LCD_CLK_PIN, gpioModePushPull, 0);
GPIO_PinModeSet(LCD_A0_PORT, LCD_A0_PIN, gpioModePushPull, 0);
GPIO_PinModeSet(LCD_TX_PORT, LCD_TX_PIN, gpioModePushPull, 0);
GPIO_PinModeSet(LCD_RST_PORT, LCD_RST_PIN, gpioModePushPull, 0);
GPIO_PinModeSet(LCD_LED_PORT, LCD_LED_PIN, gpioModePushPull, 0);

LCD_USART->CTRL |= USART_CTRL_SYNC; //set sinchronous mode
LCD_USART->FRAME |= USART_FRAME_DATABITS_EIGHT; // set nine databits

LCD_USART->CMD |= USART_CMD_TXEN; // enable transmit
LCD_USART->CMD |= USART_CMD_RXEN; // enable recieve
LCD_USART->CMD |= USART_CMD_MASTEREN; // enable master mode

LCD_USART->ROUTE |= LCD_USART_LOC; // set desired location
LCD_USART->ROUTE |= USART_ROUTE_CLKPEN; //enable clock
LCD_USART->ROUTE |= USART_ROUTE_CSPEN; //enable clock
LCD_USART->ROUTE |= USART_ROUTE_TXPEN; //enable clock

LCD_USART->CTRL |= USART_CTRL_CLKPHA_SAMPLELEADING; // set sample leading
LCD_USART->CTRL |= USART_CTRL_AUTOCS; //set auotomatic cs
LCD_USART->CTRL |= USART_CTRL_MSBF; //set most significant bit first

LCD_USART->CLKDIV = 0x0; // set some delay

}


/**************** basic functions ********************/

void LCD_ON(void)
{
// turn led on
GPIO_PinOutSet(LCD_LED_PORT, LCD_LED_PIN);

//activate sequence
GPIO_PinOutSet(LCD_RST_PORT, LCD_RST_PIN);
delay_ms(1);

GPIO_PinOutClear(LCD_RST_PORT, LCD_RST_PIN);
delay_ms(10); // warning time critical!!

GPIO_PinOutSet(LCD_RST_PORT, LCD_RST_PIN);
delay_ms(50);

LCD_CMD(LCD_CMD_idle_mode_exit); // exit idle

LCD_CMD(LCD_CMD_mode_normal); // normal mode

LCD_CMD(LCD_CMD_set_pixel_format);
LCD_data(0b00000110); // set pixel format to 18 bit;

}

void LCD_OFF(void)
{
LCD_Push(1,0x28);
GPIO_PinOutClear(LCD_LED_PORT, LCD_LED_PIN);
}

/******************** end of basic functions ***************/




/******************** data io functions ********************/

void LCD_Push(uint8_t DC,uint8_t data)
{

//wait for it
while( !(USART1->STATUS & USART_STATUS_TXBL));

GPIO->P[3].DOUT = (GPIO->P[3].DOUT & ~(1<<LCD_A0_PIN)) | ((DC & 1)<<LCD_A0_PIN);

//send data
LCD_USART->TXDATA= (data) & 0xff;

}

void LCD_CMD(uint8_t data)
{
LCD_Push(0, data);
}

void LCD_data(uint8_t data)
{
LCD_Push(1, data);
}

/******************** end of data io functions ********************/




/******************** simplifying functions ***********************/
void LCD_data_ADRESS(uint16_t start_adr, uint16_t end_adr) // send adress data
{
//send start adress
LCD_data(start_adr & 0xff); //send lower byte

//send end adress

}
void LCD_data_color(bitmap_t color) // send color data

// data needs to be R,G,B and only 6b per color

LCD_CMD(LCD_CMD_adress_page);
LCD_data_ADRESS(Y,Y+1);

LCD_CMD(LCD_CMD_memory_write_start);

}

and this is main:

Code: [Select]

int main(void)

bmp.R = 63;
bmp.G = 63;
bmp.B = 63;

GPIO_PinModeSet(gpioPortD,7,gpioModePushPull,0);

delay_init();

//initialize lcd
LCD_init();

//turn lcd on
LCD_ON();

for (a = 0; a < 0xfff; a++)
{
LCD_Pset(a,a,bmp);
}





}

void SysTick_Handler(void)
{
msTicks++;       /* increment counter necessary in Delay()*/
}

Doh! I forgot to set internal voltages
