Hi all! What event is generated if the MCU receives a data packet equal to the buffer value passed to the HAL_UARTEx_ReceiveToIdle_IT (or HAL_UARTEx_ReceiveToIdle_DMA) function? There will essentially be two events: HAL_UART_RXEVENT_TC and HAL_UART_R...
Greetings, I am using a Discovery Kit (B-U585I-IOT02A) and I want to use the LPTIM1 to wait 5 seconds (counting x ticks), at the end of the 5 seconds enter in a Callback to do something and then restart the counter again.I want to use as clock source...
We are using the STM32U575RIT6 device and performed a RX/TX swap on LPUART1, ports PC0 and PC1. When we enabled the Swap TX is properly transmitting out of PC0. But we are unable to read anything on the new RX pin PC1. Other than enabling the pin swa...
Hello,I am working with a Nucleo-F103RB board and trying to send printf output over UART using USART2. I have configured UART2 with the following parameters:Baud rate: 9600Word length: 8 bitsStop bits: 1Parity: NoneMode: TX/RXI also redirected printf...
Hi, I was trying to test the feature of "Level 2 flash lock" on my custom board. I'm having an unexpected behaviour.My total application consists of a bootloader responsable to load an application via CAN BUS through a custom communication protocol.N...

Hello,With freertos cmsis_os2 osTimerStop() returns osErrorResource despite timer is running and trigs the callback after the correct time.Is there a known bug?How a timer returning pdFALSE at test xTimerIsTimerActive (hTimer) can trig a callback???H...
Hello there, I'm using USB CDC application. I'm in a situation of receiving more than 250 bytes of data from the Windows(QT). Now my doubt is when the data is more than 64 bytes the USB FS it'll not consider right.But i revised some websites from the...
Good Day,Recently I started working with a new MCU (STM32L152). I ported some UART code to handle received data from a different MCU, which worked fine. But as soon as I started testing edge cases I saw some weird things happen. I am using the DMA on...
Hi,I am implementing RS-485 communication on the STM32G491. Based on available references, I’m currently using a custom GPIO pin for the DE (Driver Enable) signal, since the default USART1_DE pin is already allocated for another function. In the RS-4...
