STM32 MCUs Embedded software

STM32 as Modbus Master via RTU (RS-232/485) or TCP/IP,

I want to read the analog value from an external Modbus device (Slave- connected via RS232/RS485/TCP-IP) to STM32F446RE or STM32H7XX (as Modbus Master).Modbus Slave device could be any sensor or device that supports MODBUS protocolModbus Master (STM3...

Problem with application, after booting from mcuboot.

Hello All, I'm trying to chain load the baremetal application from mcuboot with stm32f429. It's chainload the application and reaches the baremetal main function but even though there is some problem with clock configuration, the application went to...

Is it better to use a hardware timer, or a freeRTOS Task with RTC for building a Metronome?

To build a metronome, I plan on using on using a freeRTOS task running a while(1) with RTC timestamps to trigger clock ticks. The freeRTOS task will run high priority but yield to other tasks which will do other work like toggle leds or other pins. U...

On L151, SPI Half duplex in pooling mode, HAL generate nb word length clock cycle more while reading

Hi FAEs and the community,On a L151 the SPI block has a strange behavior.Some time to time it generates 8 clock cycles more on a read (if I use size 8 bits) or 16 bits (if I use size 16 bits).My target is a 16 bits based half duplex SPI device.Thus i...

Is there a way for scheduling tasks on STM32L031?

Is there any task schedular for STM32? I want a bare metal task schedular for scheduling tasks so I wanted to know if there is any existing task schedular in libraries like nordic has in its SDK. If not any recommendations? The main reason I want sch...

Is there a example project for LWIP/Ethernet In-Application Programming for the STM32H743I-Eval2. Or similar STM32H7 processors?

How to flash some demo example of Cyclone on stm32?

Is there an example how to realize CycloneTCP on stm32?I'm asking because I downloaded an archive from the official website but, I don't know how to implement it in stm32.

When programming a virgin STM32L4 MCU through dfu-util 0.9, it won't exit dfu mode until power cycle.

I am working on a IoT product with the STM32L412CBU6 that requires flashing and testing at our manufacturer. I am able to program the device through DFU mode over USB using:sudo dfu-util -a 0 -i 0 -s 0x08000000:mass-erase:force:leave -R -D firmware.b...
