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...
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...
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...
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...
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 (...
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
hi i have got a problem, i never have seen before, the errors is showed on image hope some have an idea have to solve this problem. i use atollic truestudio
i am using the STM32L4 Nucleo board L4R5ZI .i am trying to configure i2c to read time from the RTC DS3231.but i am getting only data as zero.what may be the issue.i have attached the code.kindly help..
i am working on enabling the gpio interrupt..i have setted a GPio pin as a interrupt and i have given priority for the interrupt and configured as a rising edge and written callback for that..but the issue when i apply high on the GPIO the interrupt ...
