STM32 MCUs Products

In STM32F427 Microcntroller, is there a necessary to read the data register twice for getting the proper data in SPI receive mode?

internal temperature sensor stability

Hi guys and girls!I'm using STSPIN32F0, an MCU with built-in 3-phase motor driver and I'm trying to read internal temperature sensor. What I'm getting back looks to me like random walk within range of about 10 degrees Celsius (please see attachment)....

Indeterminate state of MCU

We use STM32412 for our battery operated system.A strange case is observed where MCU stopped responding.Neither it got powered up, also seems the code was not being executed.Our NRST pin is powered by the same source by which MCU is powered, so NRST ...

get the timer count

Hi,I dont know whats wrong with my code, I just want to test the timer's working .the purpose of the program is to turn off the led after a number of cycle . but this have never been happen, the led still on.PS im working wit HSI_VALUE  ((uint32_t)16...

Injected adc2 channel combined with regular channels adc1 dma stm32f103

I have 7 adc channel must be measured. 4 channels are continuously measured by dma and adc 1, 3 of them are very important measured in special moment. I want to mesured this channels by injected channel adc2. my code for this as follow, but I can not...

Trying to make an L031 wake up in 65 µs - how?

I've been trying to get an STM32L031 to periodically wakeup with minimal power consumption. The specs say it can standby at under 0.5 µA, which I can confirm, but also that it can wake up within 65 µs, which I cannot reproduce. I'm seeing a 1.6 ms de...

Inconsistence in ADC results between inputs

Using nucleo h743zi; project created in CubeMX; Multichannel ADC + DMA,.I've connected 9 pressure sensitive resistors to ADC1 inputs (IN2-IN10), and the results after AD conversion are quite inconsistent. And by inconsistence I mean that the results ...

How to get I2C functioning on a STM32F334K8T6. I2C works great with every other STM32 MCU I have

I am working with a TI PCF8574 I2C IO Expander in CubeMX, and TrueStudio. With the stm32f405 I enable the RCC, Enable I2C, and i can simply send an I2C command, and the signal is perfect on the scope. I do the same exact thing with the F334K8Tx and I...
