Sleep current
I am using STM32L010K4. I want to reduce the sleep current to 3uA ,But in the datasheet it is mentioned the the minimum sleep current is 1mA with all the peripherals disabled, which is a larg value

Resolved! can stm32 program itself without not using programing pin ?
For example how can i do this with stm32f030cc?
Resolved! STM32F042 boots in debugger only
Hi, I have designed a small project on the STM32F042F6Px MCU, and wrote a piece of software for it. Then I tried to run it outside of the debugger, and realized it won't boot. I've spent many hours on it already, and now I run out of ideas. It looks ...
Resolved! I2C SDA pin broken?
HiI am trying to configure I2C2 on an STM32F405RG on pins PB10/SCL and PB11/SDA, but I am getting very strange output on SDA. STM32 is I2C master. Using I2C example from STM32F4-Discovery folder.Using 4k7 ohm pull-ups to 3.3V.Is the output pin broken...

Resolved! 8bit data transfer on a SPI's 32bit DR register
Using STM32F767 Nucleo board and STMCubeIDE I am trying to transmit SPI data with data size of 8bit per transaction while I have setup my SPI2 in Full Duplex mode.Problem is that although I am able to transmit from MCU and receive on slave side the d...
What is the minimum system requirement to build uClinux on ST MCU ?
I am using STM32F407V MCU in our project which has 1MB Flash and 192 KB RAM.I have read about it in the community that it is possible with an external RAM (min 8MB) but I am still not sure about it.Apart from that I would also like to know how to pro...
Resolved! Is it possible to improve delay between two LL_SPI_TransmitData16
Hello,currently reading out an ADC sensor with SPI. The goal is to achieve a fast readout. Currently I am at around 200000 readouts per second, but I am wondering if this delay between two LL_SPI_TransmitData16 is because of the LL_SPI_ReceiveData16 ...
