How can i enable SYSCFG in STM32WB55RG board
Hello,Could you tell me how can i enable clock access to SYSCFG in STM32WB55RG board, because i couldn't find the proper bit to enable SYSCFG in APBENR registers in the reference manual

How to differentiate interrupts by rising or falling edge in STM32WB15?
Dears, good afternoon.We had standard hardware for telemetry using STM32G071. We decided to migrate it to STM32WB15CC in order to take advantage of BLE features.It turns out that two sensors use the same interrupt line, PA8 and PB8, although one dete...
What can prevent entering STOP mode? (STM32WB)
After some activity using BLE in the background and UART as well as some EXTI on application side, the consumption jumps from 2,4µA to 4mA, so obviously I have a wakelock. If I hotplug to the system afterwards, I can see in PWR_EXTSCR that Stop mode ...
BLE_HeartRateFreeRTOS on STM32WB55 immediately disconnects from ST-LINK
I am using the STM32WB55RG nucleo board and am trying to the BLE_HeartRateFreeRTOS example.I have installed two binaries on the coprocessor, the FUS and the BLE_Stack_full_fw according the instructions in the release notes. I confirmed with STM32cube...
Resolved! How to use PA15 (JTDI) as a GPIO
On a custom board, the RED_LED is connected to PA15, which is pulled-up by default (JTDI).The pin has been set to Push-Pull Output GPIO in CubeMX and is initialized to 0.The STM32WB55CGUx was experiencing random resets, until this particular IO was s...
Enabling/Disabling Interrupts Problem in STM32WB55RG
Hello, I want to develop a software which includes an external interrupt for sleep mode and it should be enabled before entering sleep mode. For this purpose, I use: HAL_NVIC_SetPriority(EXTI0_IRQn, 0, 0) ;HAL_NVIC_EnableIRQ(EXTI0_IRQn); When I choos...
STM32WLE5 Wake up from stop mode on EXTI for Rx
Hello,I'm trying to create a test application based on the SubGHz_Phy_Per RX example that will go into stop mode after initialization and wake up on EXTI line for an Rx window and then go back to stop mode.I want to base my test application on the Se...
GPIO CONFIGURATION
basically I'm working with a LoRaWan card that mounts your STM32WLE5CCU6 microcontroller.the problem arises from the high consumption of my product.I'm trying to program the PA8 pin of the microcontroller as an input that is always under VDD and I've...
RAK3172 LPUART sample code-LED not litting?
I am checking the below example code given in RAK3172 low level development folder.C:\en.stm32cubewl\STM32Cube_FW_WL_V1.0.0\Projects\NUCLEO-WL55JC\Examples_LL\LPUART\LPUART_WakeUpFromStop_InitThe only change I made here is for LED2 , GPIO pin changed...
Resolved! Why is 'HAL_GPIO_EXTI_Callback' defined but not used [-Wunused-function]
Learning how to use the STM32WB55RG alongside the 'Mastering STM32' by Carmine Noviello. I followed the instructions for setting up interrupts to use the NUCLEO hardware buttons, but when I build, I get a warning that 'HAL_GPIO_EXTI_Callback' defined...
