Timer and DMA

I've been trying to configure the dma and pwm timer for 5 days with no luck...There are a few things that I do not understand.As far i know timer must be connected to a DMA to push the data.1) In a timer there must be set a autoreload register (speci...

the adc result in dual mode are not in the right order

hello i am using stm32f103 for reading a 10 adc channels and i am using Dual mode regular simultaneous with DMA , the result are loaded in a buffer.the problem is the loaded data from the ADC1 are in the right order (1st data is from 1st channel)bu...

How to open the STSW-IO-LINK evaluation firmware in the STM32CubeMX development platform? STSW-IO-Link is downloaded and extracted. The *.ioc file seems to be missing in the STSW-IO-LINK firmware package!

UART set up in STM32L0

I want to stablish a UART communication between two boards (B-L072Z-LRWAN1 and 8PYA00-SIMCOM-EVB_V1.02). I tried to make a version of UART communication looking at all the examples provided by ST: static USART_HandleTypeDef huart; huart.Instanc...

Cannot Trasmit messages because CAN is always in state HAL_CAN_STATE_LISTENING?

Currently I'm trying to get CAN up and running on a STM32F469NIH6 based Board using the CubeMX libraries. Unfortunately, the documentation of the new HAL_CAN driver is very limited. I found an example in STM32Cube_FW_L4_V1.12.0\Projects\STM32L476G-EV...

no interrupts in low power (STM32L151)

Posted on January 18, 2018 at 09:50Hello everyone,I'm trying to make a device where the MCU (STM32L151) has to wake up periodically every 5 minutes and send a LoRa message. As such i want to put the device in a low power mode between messages. I rea...

IIC Slave causing issue

Hi I am using a STM32L433 IIC port as a slave. I am connecting it to another processor which has been used without any issues on another project so I know the connecting processor works fine as IIC master.I simply have set the processor up to simply...

SPI (Basics): Why do I get a signal at MISO (PB_4) when performing a write without any connection to this pin? I am using STM32F413 Discovery Board with mbed

Hi everyone, I am trying to connect my STM32F413 Discovery Board to a MAX30003 ECG but without any success. So I checked the SPI signals with a scope and discovered that I measure a signal on the MISO line as soon as I use a write command. All pins (...

How can I get the original source code for B-L475E-IOT01 ?

32F413H-DISCO: communication problem with SPI MISO pin PB_4

Hi everyone,the pin PB_4 seems to be used by any other function. This might be due to the on board WiFi module.Does anyone have the same trouble to use this SPI conectors of the discovery board? How could I solve this?Best Jens
