Hello sir, i am trying to send command to fuel gauge from stm32l476 to get data like voltage,current and temperature of battery but not getting sir.Even sda or scl line unable to see on oscilloscope. i written a code for i2c but not working .please ...
I am looking into the possibility of using a stm32 microcontroller (probably stm32f030) to directly* control the power transistors in a switch-mode power supply, in order to generate a high-power waveform.My current thinking has a PMOS switch transis...
Greetings Everybody,I am initializing STM32F030R8 Timer 3 with 48MHz clock and pre scaller 480 - 1 -> 479 and counter period 1. Technically this timer 3 interrupt should be generated at 48MHz / 480 -> 100KHz. On every interrupt i am toggling PA4 GPIO...
Ok just trying to get the bank swapping working.Loaded and flashed new firmware in to 0x08100000 all goes fine, all i need to do is to swap the flash banks.Now the code below does do the bank swap fine, but it gets stuck at the HAL_FLASH_OB_Launch();...
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...
