The LCD panel model:LM6060CBY
I want to use the gpio port initialization LCD pin，but i don't know why is the LCD screen is couldn't show Chinese characters, don't know whether I drive call errors, hope everybody to help me look at it.
Below is the LCD initialization code：
void initLCDM(void)
{
uint8_t ContrastLevel=0x2c; // default Contrast Level
GPIO_DRV_Init(NULL,lcdpins);//gpio initialization ：GPIO_DRV_Init(const gpio_input_pin_user_config_t * inputPins,const gpio_output_pin_user_config_t * outputPins)
configure_lcd_pins(0);//gpio Pin reuse
