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

Calling HAL_RTC_SetTime and HAL_RTC_SetDate during runtime causes RTC failure. Our application needs timestamp included in every packet, so during runtime we are updating the RTC datetime. But calling the above function is causing RTC interrupt failure.

HardFault Interrupt when trying to erase flash?

Hello...I am using a Nucleo WB55 board. I can run the FLASH_EraseProgram that comes with the WB55 example code successfully. I have pre-existing code and am trying to pull this into my code. I have checked the PWR and the Flash SFR in the debugger...

How to add new sequencer

Hello everyone, I am working with 3 stm32wl55JC module. 1 is receiver the other 2 is transmitter. The code has UTIL_SEQ_RegTask((1 << CFG_SEQ_Task_Sensor_Process), 0, Sensor_Process);I want to add another task which needs to work as endless loop....

I am using a NUCLEO-WL55JC1 and the LoRaWAN_End_Node example. I want to add USART1 to the example, so that I can forward the UART data over LoRa. The problem is that the interrupts for USART1 never trigger if the LoRaWAN process is also running.

If I comment out "MX_LoRaWAN_Process();" in main, then the USART1 interrupts trigger as they normally would. Could anyone offer some advice of how to add USART1 to the example?Kind regards

Hi, I am using STM32WLE5CCU6 MCU and I am trying to enable RTC Wakeup Interrupt. I use HAL_NVIC_EnableIRQ(RTC_WKUP_IRQn) but seems like my code is stuck inside it. Any ideas what can be causing that?

How to use timer interrupt to trigger the sending of BLE data every specified second for STM32WB5MMG using STM32CubeIDE?

Hi,I'm using STM32WB5MMG and want to send 8-bit data through BLE every specified duration (e.g. 1s). I have tested the Bluetooth and timer interrupt separately and both works fine. However, when I tried to trigger the Bluetooth using timer interrupt ...

Resolved! How fast is EXTI in Stop-Mode and can I make it faster?

My expectation was that a pin-interrupt using EXTI will lead to wakeup times just slightly longer than the wakeup delays named in the datasheet (below 10µs), but what I see is this (falling edge on yellow finally reached the ISR on the magenta rising...

Resolved! How can enable the SYSCFG in STM32WB55RGV6

Hi,I want to enable the SYSCGF in STM32WB55RGV6 , but when ı look the reference manuel; it says that SYSCFG is on the APB2 bus however when look the APB2ENR register there is nothing about SYSCFG . What should ı do to enable SYSCFG?

Need RTC Code with Interrupt Enable for Every 1 sec.

Hi Team,Need the RTC Code base with LSE or LSI as clock source and needs to get the interrupt at every 1sec rate. Is there any example code with these settings. Please share the code base or any example project, those are very much useful to us.Regar...
