I want to minimize LCD current consumption.
I want to minimize LCD current consumption.
LCD current consumption is too high.
After updating the LCD status, we immediately enter STOP_MODE to save current. (Keep repeating this)
I would like to reduce the LCD's current consumption by reducing the LCD's current consumption or speeding up the LCD update speed.
The LCD settings are now like this.
void MX_LCD_Init(void)
{
/* USER CODE BEGIN LCD_Init 0 */
/* USER CODE END LCD_Init 0 */
/* USER CODE BEGIN LCD_Init 1 */
/* USER CODE END LCD_Init 1 */
hlcd.Instance = LCD;
hlcd.Init.Prescaler = LCD_PRESCALER_8;
hlcd.Init.Divider = LCD_DIVIDER_16;
hlcd.Init.Duty = LCD_DUTY_1_4;
hlcd.Init.Bias = LCD_BIAS_1_3;
hlcd.Init.VoltageSource = LCD_VOLTAGESOURCE_INTERNAL;
hlcd.Init.Contrast = LCD_CONTRASTLEVEL_3;
hlcd.Init.DeadTime = LCD_DEADTIME_0;
hlcd.Init.PulseOnDuration = LCD_PULSEONDURATION_4;
hlcd.Init.MuxSegment = LCD_MUXSEGMENT_DISABLE;
hlcd.Init.BlinkMode = LCD_BLINKMODE_OFF;
hlcd.Init.BlinkFrequency = LCD_BLINKFREQUENCY_DIV128;
hlcd.Init.HighDrive = LCD_HIGHDRIVE_DISABLE;
if (HAL_LCD_Init(&hlcd) != HAL_OK)
{
Error_Handler();
}
/* USER CODE BEGIN LCD_Init 2 */
/* USER CODE END LCD_Init 2 */
}
Thank you!
have a good day~!!
