I have a custom lcd to drive with STM32L073VBTx's internal lcd driver. Duty cyle is 1/4 and the bias is 1/3. The problem is the common pins are activated sequentially even the LCD's RAM registers are equal to 0. When I activate some bits in LCD's RAM...

Hi everyone,I have stm32L053R8 nucleo64 board. I'm trying to get adc measure in low power run mode. It's not working correctly in Lprun mode but when I try in run mode it's working. In Lprun mode I only get 2 values. Half of the resolution and full o...

It's a good explanation of multiplexed driving. As far as I understand, the COM signals are activated sequentially. In my problem I cleared all RAM registers of internal LCD driver, but I saw the segments weakly in LCD's screen. When I slow down the ...

I should give an example to my problem. I've set just LCD->RAM[0]-> |= (1UL << 14) and other bits of RAM[0] and other LCD->RAM registers are 0. But I see the all 14th segment(SEG14) controlled by all 4 common pins in screen. The segment that COM0 con...
