Hi there,Lets say my device is configured as an SPI slave device with a software NSS pin. The STM32 HAL API doesn't use the SSI bit from CR1 register at all. I was wondering, what actually happens to the SPI peripheral when I manually set or clear th...
Is it absolutely impossible that HAL_Delay(1); is sometimes zero delay due for instance when it called. Minimum values can sometimes be tricky.I need a short delay around 1ms. 0.8ms or 1.2ms is allright but 0 zero is not ok.
I've a problem to setup the NUCLEO-L552ZE-Q as PD Sink.The debugger always disconnect at the following line (void HardFault_Handler(void)):CHECK_CAD_FUNCTION_CALL(USBPD_CAD_Init(USBPD_PORT_0, (USBPD_CAD_Callbacks *)&CAD_cbs, (USBPD_SettingsTypeDef *)...
Hi ,I am using STM32H753 which has flash of dual banks with 8 sectors in each banks,i am thinking to do firmware update by writing elf or bin file to second bank from the application which will be by default flashed to Bank_1 later in the application...
Hello,Please tell me the SPI polling method with LL_Driver in H7?I'm a novice in H7.Thanks.
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...
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 ...
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...
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...
