Hello,I know that LPUART can wake up MCU from STOP mode. But I'm unable to send data using DMA when entering STOP mode. I use LSE and 9600 as baudrate, so transfer takes a lot of time. I need my core to be in stop mode to reduce current consumption.I...

Hello,When I clear eeprom byte to 0xff I count it as single clear. Now when I write value to this byte I count it as single write. So according to RM I have 100k of safe read write operations like that.Can I assume that writting single bit to this by...

When I set up contrast to value less than 5 I get stuck on HAL_LCD_Init() on wait for booster, and initialization fails: /*!< Wait Until the LCD Booster is ready */ while(__HAL_LCD_GET_FLAG(hlcd, LCD_FLAG_RDY) == RESET) { if((HAL_GetTick() -...

I have LCD connected to Nucleo with STM32L073. I have configured the clocks and low power mode so with EVERYTHING turned off I get 1uA of current.Now using cube ide I have added configuration for LCD: hlcd.Instance = LCD; hlcd.Init.Prescaler = LCD...

Hi RBENF.1,Thank you for help.Yes, now I know that it is impossible to transmit in STOP mode. So for time of transmission I go to SLEEP mode. Regards,Maciek

Hi RBENF.1,Hi KDJEM.1,Yes, now I see that.So what is the best (talking about power consumption) method to transmit data using LPUART?I wanted to enter STOP mode to minimize current consumption but I see that in STOP mode LPUART TX doesn't work. So is...

Hello Kaouthar,I know that LPUART can wake up. this works perfectly.What I need is to _SEND_ data using dma while entering STOP mode. Currently every time I enter stop mode the LPUART stops transfering. I've set LSE as clock source so I was sure that...

Remains to know if this is on a 8-bit byte basis or wider.Haven't thought about that!!!! But I think that it shouldn't internally erase something that shouldnt be erasing. So if I request byte update, only this byte is erased/cleared. Otherwise if so...

STM32L0 LPUART TX using DMA and STOP mode. Is it possible?

Can I write single bit to EEPROM and count it as 1/8 of write cycle of 100k EEPROM write cycles in case of internal stm32l073 EEPROM?

LCD on nucleo STM32L073 doesn't initialize with contrast lower than 5.

What is setup for minimal current for LCD on STM32L073
