Soil Moisture sensor i2c

Hi, I need help ...I would like to be able to read the soil moisture sensor https://tinovi.com/wp-content/uploads/2019/03/PM-WCS-3-I2C.pdf of which the arduino library exists (https://github.com/tinovi/i2cArduino) using a stm32 microcontroller. There...

Oscillation in ADC measurement of DC value

Hi everyone. I am trying to measure the voltage of each battery connected in series to other. I am measuring voltages over voltage divider to reduce voltage below Vdda. When I measure the voltage of node with multi-meter there is no oscillation seen....

Can I connect a pullup resistor and 5-volt source to open drain output on unpowered STM32L476?

I am designing a product for a client based on the STM32L476 processor. My product requires separate processor and control power domains with a shared ground. The processor domain is 3.3 volts, the control domain is 5 volts. There are times when t...

Migrate from STM32F207 to STM32F429

Hi all, I am a senior developper but not so experimented with STM32 ecosystem.I have a new board equiped with a STM32F429, which is based on an old board equiped with a STM32F207.So I would like to re-use (and adapt) the firmware of the old board rat...

Want to discipline the RTC time with respect to UTC with the aid of UBLOX GPS module. what are the different ways I could do this?

1. Use 1pps as external interrupt and count the number of pulses of RTC clock, then use sub second shift feature of RTC.2. Supply the time pulse output of the UBLOX to the reference clock detection and configure the time pulse to be 60PPS and may be ...

I am using STM32F373CCT6. My application requires one timer to trigger another timer, whose output will be available on port pin. Is it possible? If yes how?

hi, I am trying to use it in the same pin for two different purposes. I'm setting 4 pins for SPI comm and after I finish using them as SPIpins I need them as normal gpio. I tried to toggle them with set and reset but didn't go so well. what should I do

for exmple, this is a part of the code:void DAC_AD5621_Write ( uint64_t DAC_Data){ HAL_GPIO_WritePin(dac_cs_GPIO_Port, dac_cs_Pin, GPIO_PIN_RESET);////Select SPI DAC_Data = (DAC_Data&0x0FFF)<<2 ; uint8_t DAC_Data1= (uint8_t)((DAC_Data>>8)&0x00FF); ui...

StdPeriph Driver canBUS (STM32f4) and HAL CAN (STM32f0) not working (SOLVED)

Hi everyone!I'm in a hurry, I have a canbus network working with stm32F4 without problems working in STD Periph drivers, and even I have 2 sTM32F0 working HAL Can with out problems (I'm gonna left the 2 config), when I try to conect both networks, th...

Does dual-bank read-while-write work properly in STM32L496?

My project uses dual-bank flash memory, bank 1 (0x0800 0000) for main code and bank 2 (0x0808 0000) for ota image and also allocated (0x080F F000) for saving the system setting. After switching bank (FB_MODE =1), the main code runs at (0x0808 0000) a...
