Local voice recognition

Hi,On the ST site local voice recognition with models from sensory is beinig advertised.I would like to prototype adding voice recognition with our product. I've created models at sensory and have an audiostream from a mems microphone on the STM32H7....

Impossible to read Std ID from bxCAN bus

bxCAN problem.Now sending data from STM32F407 to STM32F042 via bxCAN.In STM32F042, it is possibleRx interruptto read sending data (0x11, 0x22)to read DLC (2 byte)and oscilloscope that having CAN analyzing could read the sending ID/data correctly.But,...

Hello, I am using custom bootloader to update the application firmware using esp32. The bootloader code works properly in debug mode . But when in production mode the code hangs somewhere , i couldnt find where the code is getting stuck. Please assist

STM32L462E no examples to support NB-IoT or LTE develop

Hi!I have bought STM32L462E for learning NB-IoT or LTE development. However, as far as I have searched, there is too few examples about NB-IoT or LTE. en.x-cube-cellular_v6-0-0_v6.0.0 and en.patch_xcubecell-v6-0-1_v6.0.1 only give me a demonstration ...

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...
