SMBUS/ PMBUS Expansion Package

I am trying to implement the PMBUS on STM32 processor using SMBUS/PMBUS exapnsion package. I am able to execute the read and write commands. But when I am trying to execute the READ_OR_WRITE command for read operation then I receive only FF FF in the...

why current consumption in low power sleep mode(LP SLEEP) on stm32G071RBT6 is around 1mA, not less than 100uA as spec?

I'm working on NUCLEO G071RB board to measure current consumption MCU STM32G071RBT6 in LP SLEEP mode. I run the example https://github.com/STMicroelectronics/STM32CubeG0/tree/be65d071640424445aa265e8b9a058e44b8decb7/Projects/NUCLEO-G071RB/Examples/PW...

How to generate sinewave by using DAC in stm32h745xg ?

we are using stm32h745xg and I initialize DAC with timer 6 ,we enable DMA also.we are using following code  static TIM_HandleTypeDef htim; TIM_MasterConfigTypeDef sMasterConfig; /*##-1- Configure the TIM peripheral ##################################...

Hi, I am completely new to STM32 MCU programming. I am trying to make a simple variable frequency complementary square wave generator with my STM32F103C8T6 blue pill to drive an inductive load. I'd like to use a potentiometer to vary the frequency.

Frequency range I'm looking for is from 60 kHz to 200 Khz. Here's the code I generated with Cube IDE. It initializes the GPIOs, ADC, and PWMs but I don't know how to integrate a potentiometer in this code and be able to vary the frequency of the comp...

TTCAN in STM32F767

Hello I have read on the reference manual that the CAN controller can be set to work as TTCAN by setting the TTCM bit. But comparing with the STM32H7 it seems that only the latter family has the TTCAN functionality.Someone has experience with that ?R...

I am trying to establish CANbus communication using STM32F042F6P6 MCU at 27.8k speed. Please suggest me how to configure the clock in order to achieve the desired speed.

Do we have any dedicated option for Aquistic Vehicle Alert System related application? We are planning to include AVAS feature in the existing Vehicle controller,is it possible to integrate the same with the help of a secondary controller solution ?

STM32F7 RTC Accuracy/Calibration Methods?

Hello Everyone, I am using the STM32F777 and utilizing its RTC and external 32.768 crystal(LSE).Currently I am having a drift of 79s in 76 hours. it is a little bit less than a second per hour. It is not that bad but I would like to have a better res...

Unstable Current Consumption in Low Power Mode

Greetings From Turkey, We have a hardware using stm32l471. We wake up at certain times and send data to the server. Then we go back to sleep mode.Here is the our callback to switch to low power consumption mode.void low_power_callback (int time) { s...
