UART LIN DMA HAL
Hello, second day try to launch UART in LIN mode.Task: waiting break, when break flag set up, switch on DMA receiver.Transmitter works fine and send 100us break before frame.But receiver can't set UP Break Flag.And there are not everywhere examples =...
Is it possible to trigger the ADC of STM32F103xx on both compare-events in when using center aligned PWM?
Hello,I am trying to generate a unipolar PWM-Signal with an STM32f103RBT6. The Current needs to be sampled at a specific point in the PWM-Cycle. Due to the unipolar nature the current cannot be sampled at overflow/underflow. Instead it needs to be me...
Resolved! New to MCU programming, attempting to recreate STM32 step by step on STM32F779I-EVAL
Hello!As the question/topic title says, I'm new to MCU programming. I've touched C# (Unity) before and programmed an intelligent display by 4DSystems for a few applications. Unfortunately we've found some limitations on said intelligent display, so I...
How to get best ADC sample using ADC + TIM + DMA.??
Hello everyone,I am using ADC + DMA + TIMER for my analog samples on STM32 nucleoF401RE.I am new into the STM32 family.So I refer some code as per given some examples in this community.But I am not able to achieve it.I wanted to follow below method f...
AcousticBF initialization
Hi,I've been trying to setup beam forming(SMARTMIC1_V2.0.0) on my stm32f412g-discovery with two microphones connected to DFSDM peripheral but i can't quite understand how to setup it properly and examples aren't helpful.Could anyone throw some light ...
Resolved! ADC voltage with respect to MCU VDD
Hello, I am using STM32L4R9AI, the MCU VDD is powered at 1.8v and VDDA at 3.3v. in the recommended design by ST, there is ferite bead between MCU VDD and VDDA, ferite bead is basically inductor which acts as short circuit for DC current, so how can I...
D2 in RUN mode and D1 in STANDBY.
Hi,I'm using a dual core H7 and I'd like to use the only the M4 in some situation, having the D1 domain in Stand-by.It seems that there is no example for such configuration and I'm struggling to make it work by myself.I'm wondering what shall be the ...
Hello, I have a question regarding the Flash Bank organization of the STM32F4xx Devices (we use STM32F469IG with 1MB Flash).
This MCU has 1MB Flash which can be configured with the DB1M Bit in the OPTCR Regs of Flash Controller. Default is DB1M=0, which layouts the flash in single bank mode in 12 Sectors.DB1M=1 layouts the flash in dual bank mode with 2x 8 Sectors.When DB1...
DWT_Library not working for STM32F767
Hi,I'm using DWT library to generate us_delay.#include "stm32f7xx_hal.h" // change to whatever MCU you use #include "dwt_delay.h" /** * Initialization routine. * You might need to enable access to DWT registers on Cortex-M7 * DWT->LAR...
