What FMAC can do?
I want to do averaging, and finding peak value of about 1k ADC readings. I wonder if I can use FMAC to do it to offload MCU .

Resolved! RTC digital smooth calibration doesn't seems to work (stm32l083rz)
To read the frequency I am using a timer to output frequency then I am reading the value using a frequence counter. I am using the stm32l083rz chip. I have a gate time of 32 seconds on my frequence counter.I am trying to compensate the drift due to t...
Resolved! Timer slave trigger polarity for input capture
I want to use TIM1_CH1 to measure pulse width. TIM1 works under slave reset mode. The input trigger is TI1FP1. Ideally, TIM1 resets upon rising input, then TIM1_CH1 captures the falling edge. The CCR1 value would be the pulse width. The problem is th...
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....
