I have a bunch of debugMsg() calls throughout my code. Is there a way to automatically strip those out during a build?
Is there any example to flash firmware image to external flash memory over SPI and execute in place.Device - STM32H7S3L8
Hello,I found an interesting problem with the USB controller. Our device uses MCU STM32F756, with USB in FS Device mode.We have a total of three USB IN endpoints, controlled via Azure RTOS / USBX middleware. With a heavy load on USB endpoints, someti...
Hi, i want the communication between stm32f411re board and raspberry pi 4. i tried to do with uart2 through USB cable it is working fine. but sometimes it is not able to communicate properly. there is a delay while communicating sometimes. will i2c o...
I am writing an embedded software project that includes BLE GATT protocol with stm32wb15 mcu.Based on the "BLE_HeartRate" example, to use stop1 and standby in the project;I activated "CFG_LPM_SUPPORTED 1" and "CFG_LPM_STANDBY_SUPPORTED 1".Question 1I...
Can STM32L431 configure the RX of the serial port to EXTI wake-up in STOP2 mode? Why can't I wake up? And idle interrupts cannot be used either. The manual states that the EXTI and RX pins have been connected together in hardware, but the STOP2 mode ...
