Hi, I'm looking for a NB-IoT capable modem module that could be used together with STM32L4 B-L475E-IOT01A Discovery kit and the X-NUCLEO-STMODA1 expansion board.
The idea is to create a FreeRTOS application that can send sensor data to AWS IoT.

wrong IS_RCC_PLLN_VALUE macro
Hi !This issue is still not fixed in the current F4 firmware V1.25.If USE_FULL_ASSERT is used the parameter check for a valid calculated value of PLLN=96 by STM32CubeMx fails.The old issue was closed therefore please raise a ticket (again) - thanks !...
USB PD Sink Configuration for a wide input range charger?
We are designing a USB PD LiPo charger that can receive power from a variety of USB PD sources. It is based around a charger IC designed to handle a wide range of input voltages with internal control of the current draw. For example, our design can d...
STM32Cube license: Can I integrate the repository via "git submodule" into an open source project?
The licensing of STM32Cube is a bit special. BSD is used for most of the components but some use the more restrictive "ST SLA0044" instead (https://www.st.com/resource/en/license_agreement/SLA0044.txt).It says, among other things, that "...no use, re...

Resolved! Potential bug in STM32H HAL v1.8.0: enabling CANFD transmission request for a given packet may disable TX for previous already queued requests.
The 2 instances where hfdcan->Instance->TXBAR is written in stm32h7xx_hal_fdcan.c (as means of activating a TX reqeust for a given CANFD packet) use a direct value assignment to the register:hfdcan->Instance->TXBAR = BufferIndex;hfdcan->Instance->TXB...
How to implement USB to lots of interface (UART/I2C/PWM/SPI/GPIO...)
If we want to implement USB to multi-interface at the same timesUSB to UART1~3USB to I2C1~3USB to SPI USB to PWMUSB to SD cardWe use STM32F4 , USB 2.0 have 5 in / 5 out endpointsi think we could use USB mass storage protocol to implement USB to SDbu...
STM32F070CB custom USB DFU Bootloader for flashing firmware over USB.
Hi everyone! I need to write a bootloader for STM32F070CB. What I want is to be able to do Device Firmware Update over USB. On the PC side, there will be a software written in QT so the end-user can update device firmware. I haven't written any bootl...
