How do I clear all the closed USART connections?
I have been playing around with USART. See pic....How do I clear out all the console connections?
Nucleo-G071 + STM32CubeIDE has I2C working for one project but not others
I have a situation where I'm starting to work with the STM32CubeIDE and STM32 MCUs, and I've followed some tutorials with relatively positive success. However, I ran into an issue where I got I2C working on one project, but I cannot for the life of m...
Resolved! stm32f1xx_ll_gpio.h, wrong LL_GPIO_PIN_x definition
Hello the pin definition> 7 in the stm32f1xx_ll_gpio.h file seems to be wrong: in fact when I use LL_GPIO_PIN_8 with the function HAL_GPIO_WritePin (GPIO_TypeDef * GPIOx, uint16_t GPIO_Pin, GPIO_PinState PinState)the ODR0 bit of the port concerned is...
In 'F407, bxCAN does not go to Bus-Off
In STM32F407, I have set bxCAN with CAN_MCR.ABOM=0 and CAN_MCR.NART=0. With the bus lines after transceiver (PHY) left open, after trying to transmit, transmitter transmits continuously forever, with CAN_ESR.LEC=0b011 for Acknowledgement Error (which...
Can SRAM1, SRAM2, SRAM3 be treated as one continuous memory region?
(This is regarding STM32H75x)SRAM1, SRAM2, and SRAM3 are separate in the memory map, but they are continuous - there are no gaps between them: Can they be treated as continuous with respect to the linker, for example:RAM_D2 (xrw) : ORIGIN = 0x3...
Resolved! Micron QSPI Nonvolatile Config register Write not working.
Hi Everyone, I am using STM32H757I-EVAL board and the onboard Twin Quad SPI Nor Flash ( MT25QL512ABB8ESF-0SIT ). I have configured QSPI to operate in DUAL Flash mode.I am able to perform memory read, memory write, memory erase, and internal configura...
UART Rx Threshold or FIFO Full interrupt not triggered
Hi, I created a test project to wake up L562MCU from STOP Mode when UART RxFIFO Threshold reached or full interrupt triggered or USER Button pressed.The project is based on Example project "UART_WakeUpFromStopUsingFIFO" for L562-DK. Test 1: Rx thresh...
Nucleo overcurrent and overheating issue
I am trying to drive inkjet printer cartridge using Nucleo F746ZG board. But at the moment i connect cartridge to the nucleo board, Controller heats up very much and over current LED starts blinking and if i continue connection about 10 Minutes then...
