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

[BLE] No sleep and No RF when added PLL to Clocks
HI, I added PLL to the Clocks , but that totally broke the sleep behaviour and I get no RF. RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI|RCC_OSCILLATORTYPE_HSE|RCC_OSCILLATORTYPE_LSE; RCC_OscInitStruct.HSEState = RCC_HSE_ON; RCC_OscInitS...
Recommended NT2016SF-32M-END5875A for STM32WL design
We design a new product where we use STM32WL microcontroller and in the datasheet ST is recommended to use NT2016SF-32M-END5875A manufactured by NDK but we dont found it to buy.Can you provide some distributors where we can buy this TCXO?Can you prov...
Resolved! STM32WLE5CC HSE32 TCXO input
Greetings!I'm designing a board using STM32WLE5CCU6 MCU and decided to use a 32-MHz Clipped Sine Wave TCXO instead of a crystal for the HSE32 clock.I have a question regarding the additional circuitry between the TCXO and MCU, is an AC coupling capac...
Resolved! STM32WB55 User Manual RCC register is missing bit 18????
I am trying to incorporate the X-Cube-EEPROM package into an existing STM32WB55 Nucleo design that I have. In the process one of the compile errors refers to an RCC bit:'RCC_CR_HSEBYP' undeclared (first use in this function); did you mean 'RCC_BDCR...
Resolved! About the LSE Crystall to the STM32WB55
In STM32WB55 the LSF must be 32KHz or it can be others like 42KHz etc. as well? Thanks.
Verification of Crystal suitability for STM32WL design
We have a design implementing the STM32WL55/WE5.The recommended crystals on the reference designs and literature are:NX2012SA 32.768KHz EXS00A-MU00527X2NX2016SA 32MHz EXS00A-CS06465I want to verify that it is OK to use the following:For NX2016SA: EI...
Resolved! How to change TCXO to Quartz Clock configuration SW LoRa_AT_Slave
Hi, I would like to try nucleo-WL55 in LoRa Node with Quatz and see temperature influence in RF signal.So I have unsolder R2, and solder R39/R40. But now LoRaWAN_AT_Slave does not work anymore, even if I change TCXO to Quartz in .ioc file. I can see ...
Resolved! BLE server without LSE crystal as clock error. Working on WB55 board but not a custom board
I am trying to setup a ble server on a stm32 board that does not have a lse crystal. I have followed the normal steps and the steps that use the hse crystal instead (https://community.st.com/s/article/configuring-stm32wb-for-bluetooth-le-without-an-l...
Resolved! SYSCLK vs SystemCoreClock
Hello,I want to know difference between SYSCLK and SystemCoreClok.When ı try to configure clock of different peripherals I saw terms SYSCLK and SystemCoreClock. I use MSI for SYSCLK which is configured to 32MHZ and for cpu1 ı divided sysclk by 4 and ...
