STM32 RS485 Communication does not work as expected
I have a weight cell which replies to specific frames over RS485 (cell contains its own communication protocol). Manufacturer has a software to test the cell so I connect it to my pc using a RS485 to USB converter and I am able to connect to the cell...
STM32 In-Application Programming for updating the configuration variables
Hi,I have a STM32L4R5ZI based system that has some configuration parameters to be set based on the customer requirements. I want to make those settings being at customer place. I will not be having any compiler to modify the code for updating these s...
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...
