Resolved! Incorrectly written AFIO_MAPR.SWJ_CFG bits in CubeF1/LL

In stm32f1xx_ll_gpio.h, LL_GPIO_AF_EnableRemap_SWJ(), LL_GPIO_AF_Remap_SWJ_NONJTRST, LL_GPIO_AF_Remap_SWJ_NOJTAG(), LL_GPIO_AF_DisableRemap_SWJ() all use SET_BIT(AFIO->MAPR, AFIO_MAPR_SWJ_CFG_xxxxx);which is incorrect, as SET_BIT is #define SET_BIT(R...

Reading pins of a port in one line of code

Posted on October 14, 2015 at 05:17I am working on project which is generated by Cube and uses HAL drivers. I require to read states of a number of pins on a port. Currently I am doing like this: //read PC0 to PC7 to check for state (on or off) re...

Why my project stuck in HAL_Delay()?

Hi,i have started this project using X-Cube-IOTA1 package and i added all libraries i need to replicate the same project example which is IOTA-Client. i manage to compile my version and run in the the STM32 B-L4S5-IOTA1 using freeRTOS, but the proble...

STM32G473CBT freezes jumping to bootloader

I have a custom board using the STM32G473CBT6 MCU. BOOT0 is pulled-down by a 100k resistor and is used as GPIO (output) at runtime. The firmware is generated by CubeMX, with the addition of a C++ file for the 'user' application. The board works fine,...

Using NVIC to measure frecuency of a multiple pulse signal in StopMode2 is a good option?

I am trying to create a frequency meter in a STM32U575ZI microcontroller that works with ThreadX and low power consumption using the low power timers LPTIM3 and LPTIM4, as well as an interrupt using EXTI 14. In summary, I use LPTIM4 to count input p...

Resolved! Tasks work strangely in FREERTOS

Started learning FREERTOS and ran into a problem.I showed 3 pieces of code of the same tasks.All 3 pieces of code work differently.Code 1void Task1(void *argument) { int j = 0; for(;;) { HAL_GPIO_TogglePin(GPIOB, GPIO_PIN_0); for(j=0; j<100000...

Resolved! No GPIOx registers are present in System Viewer for STM32G051 or STM32G061 microcontrollers during debug session

No GPIOx registers are present in System Viewer for STM32G051 or STM32G061 microcontrollers during debug session. There are 12 different .sfr files for each different variant of STM32G0 microcontroller, but only the above two lack GPIO registers in S...

Multiple EXTI GPIO EVENTS-STM32G0 I would to know is someone could provide some tips on using GPIOs as External Events (EXTI) sources on STM2G0 HAL. Any information is welcome BR Gilberto

What STM32 development boards support developing with a High Speed USB device?

It should use a chip with low pincount/small package.I need to connect a UART an SPI and a few GPIOs.Even chips with HS USB seems to only support FS USB on the development boards I looked at. While the chip does not use too much bandwidth, there are ...

Resolved! Two questions about HAL_GPIO_EXTI_IRQHandler

1- Using cubre-mx I enabled two IRQ lines, each generate its own ISRvoid EXTI0_IRQHandler(void){ HAL_GPIO_EXTI_IRQHandler(GPIO_PIN_0);}andvoid EXTI15_10_IRQHandler(void){ HAL_GPIO_EXTI_IRQHandler(GPIO_PIN_0);}Why HAL joint together both IRQ handlers ...
