I am trying to do I2C communication between STM32L476RC and Fuel gauge IC(BQ40Z50R2),for that i am using following components: 1) STM32L476RC Controller 2) BQ40Z50R2 Fuel gauge IC 3) STM32 CubeMx software 4) Keil softwareThe datasheet...
Hi,i'm using STM32F40G DISVOVERY board. when i measue D1 i see 2.5 volt. Also when i measure 5V pin, i see 2.5 volt. What should i do? Can replacing D1 by D2 solve the problem?
/* I have attached code here, This explains if you press interrupt button it enters into the sleep mode, In sleep mode It is initializing all GPIO and clk are fine but after Disable GPIOs clock board breaks means showing ST link error . This erro...
Hi,I am using STM32f051R8 for industrial controller application. I am using cubeMx tool to generate codes and Keil v5 to compile. One of my project requires to read accurate ADC channel read. So, I decided to read Vrefint channel to get best accuracy...
My work on stm32f405 just started last month. It means I don't know very much about it, and I have been working on other C/C++ applications development. The stm32 MCU board I have is given in snapshots.I have been working on time interval's computati...
I've been fighting with this too long and can't figure it out. I've added uart communication for use with printf() by implementing the following in syscalls.c:__attribute__((weak)) int _write(int file, char *ptr, int len) { HAL_StatusTypeDef statu...

This is probably more of a wish list item than a question that can be solved - I'm using an STM32L4 chip's SAI to interface to an I2s microphone (SPH0645lm4h Knowles microphone). It works well. But things would be even better if the I2s reception cou...
Hi, I am using stm32f103c8t6 connected to a rotary encoder using SPL. I was planning to use TIMER 1 in encoder mode, but probably I had made a mistake by connecting channel A of encoder to PB13 (T1C1N) and channel B to PB14(T1C2N) - this se...
