Stm32L452 RTC Clock Drift with use---related to entering/exiting shutdown mode?

Hi. I'm operating an stm32l452 MCU which enters and exits shutdown mode frequently, and am using the internal RTC of the chip to keep track of time as the days progress. I have noticed that over continued use (with frequent exits/entrances to shutdow...

ETM Trace on STM32L486QG

I want to do ETM trace on STM32L486QG. When I look at my trace probe: I see I have to connect 5 pins TClock, T0,T1,T2,T3.I am look at which pins to connect to on the processor. I found this document https://www.st.com/resource/en/datasheet/stm32l486q...

STM32F030K6, I2C Slave, HAL_I2C_Slave_Seq_Transmit_IT(), reset MCU when datas are "0x00"

Hi,I have a issue with I2C Slave on an STM32F030K6.Project is generated with : CubeMx 5.6.2Hal version: STM32Cube FW_F0 V1.11.0IDE : IAR 8.40.1The STM32 is configured as an I2C Slave ans answers to an other STM32F0 HAL_I2C_Mem_Read() request.I2C is c...

Issue with resetting timer count in encoder mode with external interrupt (stm32f411)

So I am trying to use the encoder mode that's built into the timer to get accurate encoder step count, which have worked flawlessly. I tried to use PA0 as the external interrupt that detects the rising edge to the index pulse. However, when I set the...

Readout protection from level 1 to 0

I've a STM32L451 uC with 1.8V of supply voltage. I've the readout protection at level 1, but I can't go back to the 0 level. I tried with stlink and jlink ( j-link STM32 Unlock) but it doesn't work.is there a sequence to solve the problem ?The BOR i...

Missing information in RM0451 (L0 reference manual)

Hello,The reference manual for the L0x0 family is missing the ADC sampling time bits signification, p.287 table 13.11.6Best regards.

Current Consumption in STOP MODE ON STM32L100C Discovery Board

Hi,I am working with the STM32L100C Discovery Board and trying to implement the stop mode to reduce current consumption. According to the data sheet, in stop mode the current can be reduced up to µA but I am still having about 26mA. This is my stop_m...

Timer triggered ADC acquisition through DMA

Hi guys,I have an application that requires TIM2 Ch2 to trigger ADC Ch3 every time the timer has a rising edge and in order to reduce the load on the CPU I'm doing it through DMA. Now I seem to have configured my application correctly as the ADC is o...
