Hi thereHow to calculate the maximal possible CPU execution time for the STM32WB55 when running fetching the code from external flash?Kind Regrads
I have a board NUCLEO-WB55RG and STM32CubeProgrammer v2.12.0, I'm trying to write OTP area to address 0x1FFF7000, but I got errors.I edit with GUI and I got error message: "Memory edition verification failed", with CLI I have this error:./STM32_Progr...
Dear All,I have managed to get the LoRaWAN_end_Node_DualCoreFreeRTOS sample working and now I am trying to get this sample to perform a continuous wave.I know that I need to use the mailbox system in order to send the proper settings and commands, bu...
Hi,I want to know the difference between EXTI PR1 and EXTI PR2 registers in stm32wb55xx.
We are using an STM32WL55 (NUCLEO-WL55JC2) and don't understand RCC_BDCR_RTCEN. Our system is configured to be woken up from Stop 1 Mode via RTC wake-up, clocked by LSE. This works, but we wonder about a detail.According to RM0453, RCC_BDCR_RTCEN is ...
Hello,I am currently using STM32WB55 with QSPI external flash.Currently, the plan is to use it without Bluetooth, for now.I am able to write and read the flash in the program.The plan:Record for 24 hours with DMA from sensors to flash.Upload another ...
The stm32wb55 writes data to the sd card in real time through FATFS, and the function f_write() will take tens of ms. I want to use two buffers, one buffer to store data, and one buffer to write data to and from the sd card (can this avoid the delay ...
I have a custom board running the STM32WB55. My medium term goal is to use BLE to perform OTA updates for my firmware. I'm trying to leverage the BLE_p2pServer BLE_p2pServer_ota examples from the as a starting point, but I'm getting stuck at one o...
