Second Controller STM32F1003 on Discovery board STM32F4x

Hi,On the Disco board with STM23F4x there is a STM32F1003.What is it there for, and how do I access it?Thanks,Johannes

Circular DMA bursts

I use circular DMA with a buffer of size n (on a G431) to create bursts that are not necessarily equal to a multiple of n in size. This works fine, I start and stop a timer and end up somewhere in the DMA buffer array (say, at buffer[m] where 0<=m<n)...

How do I implement the overflow for an LPTIM in encoder mode in STOP2

Hi there,I use an STM32L433 and have to evaluate a quadrature encoder in a battery device.For this I want to use the LPTIM1 in encoder mode.My problem is that the 16 bit of the timer is not enough to save the desired position.As soon as there is an o...

I am trying to interface an stm32f412 with a Texas instruments ADS7953 in the auto 2 mode. I am using the TI mode and using the HAL DMA drivers to talk to the ADS7953. However after programming I am not getting the intended result.

As I understand it TI mode consists of high polarity clock, 1st edge phase and nss after every frame. I think the problem I have is the clock is running even with NSS high. This causes the bits to be shifted out of the ADS7953. It will be great if an...

IR remote

I'm trying to code IR remote which uses NEC protocol using STM32f030 .I'm able to do the code under while(1) as as a GPIO input But i'm not able to implement it as an interrupt . Kindly help me regarding the same

Simulink target ADC not working for STM32F091

I am trying to use the ADC_Read block from the simulink support package. I am able to use the ADC1 from a STM32F4 MCU but when I try to use the ADC from STM32F0 MCU it doesn't work. All the configurations should be fine since many other blocks work (...

What is the time it takes for the STM32l082kb to wake up it's adc? and is a ferrite bead necessary?

For my new project i have to use an ADC to measure the peak value of a pulse. This pulse wakes up the microcontroller from stop mode, and the processor has to wake up the internal adc to take the samples needed. Unfortunately i can't find the time it...

Resolved! STM32F769 PWM using DMA on two channels PA2 and PA3 issue

Hello,I have an issue with using two channels of DMA to generate the PWM on PA2 and PA3 pins.I configured using CubeMX TIM2 PWM Generation CH3 and CH4. I have added the DMA memory to peripheral for PA2 DMA1Stream1 and for PA3 DMA1Stream6.The issue I ...
