UART Rx Interrupt triggered, but state is READY, when it should be BUSY, causing Rx Data to not be returned.
STM32H743Using USART3 in Asynchronous mode with interrupt. The hope is to use this with FreeRTOS+CLII am able to Tx as expected. Rx will trigger the interrupt, but the RX State is READY when it should be BUSY. This causes the value to not be saved, a...
FOTA using UART bluetooth
I am using an STM32F302CB MCU, I intend to program my device remotely via a mobile app connected with the embedded system through a BT( UART connected).What I understood:-1.) The ST bootloader can be used to flash the MCU by sending some commands to ...
on mapping gpio to EXTI on stm32f479xx
Hello,I'm maintaining an RTOS application. It apparently has some GPIOs configured as input interrupts and its startup assembler code has some references to EXTI interrupt lines and handlers like this.... .word EXTI0_IRQHandler /* EXTI Line...
Can't receive from USB bulk endpoint despite Windows enumerates and libusb reads descriptor of STM32 custom device class (USB_OTG periph)
For a fast ADC sampling USB device, I am using the USB 2.0 High Speed capable STM32F733 with the embedded USB-HS PHY. In USBView, I can see that the device is enumerated, the libusb code opens the device and claims interface, but when I try to receiv...
Only DFU is recognized, not CDC on F070CB
Good afternoonReceived my first own PCB back with a STM32F070CB chip...When I pull the Boot0 pin high, I see that the host PC sees it as a DFU device...But under normal condition when using the CDC class I see following message on the host:[17770.689...
Resolved! What are the USB_FS interface power requirements for the STM32L552CE?
I'm designing for a project using the STM32L552CET6 to hold me over until the STM32L4P5CGT6 is in stock. The datasheet (DS12737 Rev4) for the STM32L552xx line describes the interface as available in Table 2. The reference manual mentions an independe...
FATfs on SPI flash or to use direct access to bloacks
Hello,I've checked multiple threads on FATfs design for SPI flash. I see, there are some advantages of using FATfs like standard code, modularity etc. but are there any disadvantages apart from adding one more layer of execution between application a...
__HAL_LOCK(x) function in STM32 with FreeRTOS
I'm using STM32F767 and referring STM32746G-Discovery code. I've question regarding __HAL_LOCK() function. if I'm using FreeRTOS, I've created 2 threads, one to to handle QSPI interface for flash and second thread to handle CAN communication and read...
