Resolved! RM0090 SAI description flaw

RM0090, SAI chapter:Each FIFO word contains one audio frame.This is incorrect. The correct formulation can be found e.g. in RM0410:Each FIFO word contains one audio slot.Thanks,JW

How to read sensor data from the B475E-IOT01A board and send it to a Ublox board through the UART protocol?

I have a B-L475-IOT01A Discovery Board which I would like to get its accelerometer data from and transfer it to a Ublox EVB-ODIN-W2 board using the UART protocol. Is there a guide on how to do this?

Resolved! Is there any manual or document available which enlists all the HAL_HRTIM functions and their usages?

Hi, I have been working on STM32 G474RE Nucleo Board and I need to configure HRTIM for generating PWM signals. Is there any documentation or user manual available related to the HAL functions which are implemented for HRTIM? Thanks in advance.

Resolved! STM32 Timer Output Compare Interrupt all interrupt flags set at once

Hello!I'm trying to set up the output compare channels of TIM3 of an STM32F103RB MCU. For now I only enabled channel 1, but later I'll need CH2 and CH3 as well. When CH1 triggers, the TIM3->SR register gets the value of 0x0000001f, i have looked at i...

How to control the blinking rate of RGB LED?

Hi there!I have been trying to interface the RGB LED with STM32L152RE. My requirement is not only to control its color but also its blinking rate. I used a timer for generating PWM signals on its three channels to control different colors of RGB LED....

Resolved! STM32 Microcontroller with at least 6 ADCs and advanced PWM with deadtime management

Hi,Would you please help me to choose a STM32 microcontroller which must have 6 number of ADCs and must be capable of generating PWM signals with deadtime. Thanks in advance.BR

Resolved! Using Sparkfun Arduino Qwiic Shield with STM32H7451-DISCO

I am attempting to drive some I2C 5.0v / 3.3v peripherals via the Sparkfun Arduino Qwiic Shield connected to an STM32H7451-DISCO.I can't seem to raise the devices on the I2C bus despite being able to communicate with the audio codec and LCD which are...

Resolved! Is it possible to flash FW compiled for STM32L476RC in to STM32L476RE?

Hello, I was wondering if the FW compiled for STM32L476RC could be safety flashed in STM32L476RE which is the same core but with a larger size of flash.

Collecting the ADC values from rising edge till the falling edge of the pulse

I am using the DMA to collect the ADC data's. The ADC data's are now configured in a single mode and ADC is triggered at the rising edge of a pulse (I am using TIM8 for the pulse generation and the pulse can be set for 10us till 400us, i am also usin...
