stm8l lcd setting

[David.Cheng]

HOW to code this table?

void LCD_GLASS_Init(void)
{
 /*
 The LCD is configured as follow:
 - clock source = LSE (32.768 KHz)
 - Voltage source = Internal
 - Prescaler = 2
 - Divider = 18 (16 + 2) 
 - Mode = 1/8 Duty, 1/4 Bias
 - LCD frequency = (clock source * Duty) / (Prescaler * Divider)
 = 114 Hz ==> Frame frequency = 28,5 Hz*/
 
 CLK_PeripheralClockConfig(CLK_Peripheral_RTC, ENABLE);
 /* Enable LCD clock */
 CLK_PeripheralClockConfig(CLK_Peripheral_LCD, ENABLE);
 CLK_RTCClockConfig(CLK_RTCCLKSource_LSE, CLK_RTCCLKDiv_1);
 
 /* Initialize the LCD */
 LCD_Init(LCD_Prescaler_4, LCD_Divider_16, LCD_Duty_1_4,
 LCD_Bias_1_3, LCD_VoltageSource_Internal);
 
 /* Mask register*/
 LCD_PortMaskConfig(LCD_PortMaskRegister_0, 0xFF);
 LCD_PortMaskConfig(LCD_PortMaskRegister_1, 0x0F);
 //LCD_PortMaskConfig(LCD_PortMaskRegister_2, 0x00);
 //LCD_PortMaskConfig(LCD_PortMaskRegister_3, 0xFF);
 //LCD_PortMaskConfig(LCD_PortMaskRegister_4, 0xFF);
 //LCD_PortMaskConfig(LCD_PortMaskRegister_5, 0x0F);
 
 LCD_ContrastConfig(LCD_Contrast_Level_7);
 
 //LCD_DeadTimeConfig(LCD_DeadTime_0); 
 LCD_PulseOnDurationConfig(LCD_PulseOnDuration_7);
 
 LCD_Cmd(ENABLE); /*!< Enable LCD peripheral */
}

 call this in main function

LCD_GLASS_Init();
 
 
 LCD->RAM[0] = 0x01;
 LCD->RAM[1] = 0x0f;

nothing shows, the battery voltage is 3.28, I found the power is not enough for lcd
