Hey there.Iam using a L432KC for a simpe periodic SPI communication with another device.when the communication is done the device is sent to sleep.and then the MCU goes into shutdown mode with HAL_PWR_EnterSTANDBYMode();The problem is that the device...

Hey There, iam using a LIS2DW12 on a STEVAL-MKI179V1 eval board :https://www.st.com/en/evaluation-tools/steval-mki179v1.html#overviewhttps://www.st.com/en/mems-and-sensors/lis2dw12.html#overviewThe Datasheet says that it has 50nA standbycurrent and 1...

Hey there.. iam currently working with a L432KC on a custom made PCB.My programm reads a sensor value (I2C) and sends it so another device via SPI.This operation is performed every minute.iam using the HAL_Delay(60000) command to wait fot the next mi...

Hey there, i recently designed a PCB with a litte STM32 Procect.Now i cant programm my MCU by SWD.MCU : STM32L432KCST-Link : ST-Link v2.1 broken off a nucleo64 (according to UM1724)ive got wires to pin 23 (SWDIO), pin 24 (SWCLK), pin 4 (NRST),GND and...

Hey,i want to implement a Modbus TCP IP client on my STM32L432KC board.is there a good libary you would recommend me? iam using a W5100 Ehternet shield connnected via SPI.i want to read/write holding registers on the Modbus master..thanks!

Hi. Thank you for responding to my Post. The Problem on my application was the SA0 Pin. This sets the least Bit of the I2C Address. The Datasheet says, that this pin is pulled up to vcc with R10K. Thats where my current went to. I solved the Problem...

thank you! that is exactly what i was looking for!i used theese HAL_functions : HAL_PWREx_EnableGPIOPullUp(PWR_GPIO_B, GPIO_PIN_0); //NSS HAL_PWREx_EnablePullUpPullDownConfig();i should do that to all GPIOs wich are configured as a output right?Doe...

THIS IS THE PROBLEM!!! thank you!the Datasheet says, that this pullup cant be deactivated:expressionless_face: looks like i have do adjust my code and create a new PCB........thank you very much for your help!

100k as pullup give me the same current reading ..CS is connected to 3.3V to acticate the i2c communication. SD0 is tied to GND to set the i2c adress as discriped in the Datasheet.Int1 and int2 are not connected.unfortunately i will not have a differ...

Hey, i just connected 10k between SCL/VDD_IO and SDA/VDD_IO as mentioned in the Datasheet.the current in standy is now 142 uA in Standby (only VDD_IO).the current for the whole chip is now 144uA in Standby... still far away from the Datasheet value....
