I use STM32L496To save current to a minimum, It briefly enters NOMAL mode (0.2mA ~ 6.3mA) and updates the LCD numbers, then stays in STOP mode (0.2mA) for about 1 second and then wakes up with RTC.I keep repeating this.However, in STOP mode, it alway...

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 LC...

I am using STM8S003F3. If the supply voltage of STM8S003F3 is 3.3v, the ADC works well.However, if you apply a supply voltage lower than 3.3V, the ADC will not work.I hope the ADC works well at 3.0V.For reference, I know that the minimum supply volta...

There is a problem with audio playback on the STM32L4.

hlcd.Init.Prescaler = LCD_PRESCALER_1; Keep this Setting and make LCD letters darker

[STM32] Why does the LCD current gradually increase and then decrease gradually?

I want to minimize LCD current consumption.

if you apply a supply voltage lower than 3.3V, the ADC will not work.
