STM32 MCUs Embedded software

Resolved! Will code written for STM32f103 blue pill port easily to STM32f103 nucleo? The UM1724 manual is not that clear to me. I used FreeRTOS and Libopencm3 macros in the code. The problem I am having is not being able to debug using USB and minicom on Linux.

how to use sleep mode in stm32f401re with freertos enabled.

I am using lower power mode for my application. When I enable sleep mode in the task it is getting waked once it enters the sleep mode. I want to my application to stay in the sleep mode until the external interrupt occurs.

Using USB HAL for MSC with multiple access to storage

I am working on a design using STM32L433 as a composite USB (CDC and MSC) device using the STM32L4xx HAL and FreeRTOS. I have the device enumerating and I now need to add access to the storage medium (eMMC). The challenge I am facing is that the devi...

Can FreeRTOS only "do things" during the Timer Tick interrupt (typically every 1 ms?)

I'm trying to understand how the internals of FreeRTOS work and in particular I'm curious whether FreeRTOS thread execution and handling only occurs with 1 ms "granularity". Let's take an example, let's assume I create a thread that only takes 0.3 ms...

STM32G4 Flash Erase trouble at address greater than half flash

Hello,i have an issue with erasing flash on STM32G4.When i try to erase addresses above half of the flash (above 0x8010000), it does not erase anything. It works when i try to erase below this address.However the function HAL_FLASHEx_Erase returns HA...

Resolved! STM32F4 USB composite device driver MISSING!

Hi!I currently work on USB composite device (CDC + MSC). I putted together a program with help from:https://sudonull.com/post/68144-CDC-MSC-USB-Composite-Device-on-STM32-HALhttps://www.programmersought.com/article/18127793400/The thing is, i don't kn...

BUG found on HAL STM32L4 HAL_UARTEx_ReceiveToIdle_IT(). This function works on STM32F0 HAL V1.11.3 but not on STM32L4 V1.17 An update is needed to solve bug when UART bytes is equaly to RxXferSize, because currently it stays on endless IT loop

A simple compare between the two HAL Versions shows that line 4730 "huart->ReceptionType = HAL_UART_RECEPTION_STANDARD" needs to be moved at position line 4708. This fixes the bug, same as it is implemented in HAL For STM32F0 series

Resolved! How can I make an OTG USB connection to an STM32H753 using a USB Type-C receptacle?

I have an STM32H753 using a USB OTG-HS peripheral configured for full speed mode, which is connected to a USB Type-C receptacle. The goal is to connect to a Galaxy S8 where the S8 is the host and the STM is the peripheral. However, this is a Type-C t...

Resolved! Flash loader with another mcu

Hi Everyone,I want to do e flash loader device that can be load binary to mcu via Swdio pin. Is any one can give advice about this? Maybe stlink hardware can be use or any STM32-Disco board can be use I don't know. I just want to create something li...

Resolved! What is the simplest approach for 1-bit shared memory between bootloader & application?

I am trying to get an application to set a flag to non-volatile memory to communicate to the bootloader after reset to reprogram the application image. I am using the STM32L496 MCU.EEPROM seems to be the weapon of choice, but our team has EEPROM on b...
