Hi, I try to save the configuration application in the internal flash memory of my STM32WB55 with this next fonction : static int write(long offset, const uint8_t *buf, size_t size)
{
size_t i;
uint32_t addr = stm32wb_onchip_flash.addr + of...
Hi, I would like to use OpenBootloader on my STM32WB35 but I do not find any exemple about it. There is a repository on the official STM github but it is empty : Maybe somebody from STM can correct this I already checked the STM32Wb package and th...
Hi, I try to implement an USB CCID device on an STM32WB55 MCU and the stm32_mw_usb_device release V2.11. I do not find any documentation about how to use this implementation... Today, I created an USB peripheral that is recognised by Windows as CCID ...
Update: I tried to lock the sempahores 2 and 7 before trying to write in the flash without success. i use this fonction : while(LL_HSEM_2StepLock(HSEM, 7, 0)) { }; LL_HSEM_ReleaseLock(HSEM, 2, 0); For the moment, i do not use the BLE stack in my pro...
Hi, since I wrote this question I have succeeded to create a CCID device. But when i try to send the first frame to the device (frame type : PC to reader ICC power off) i have in response a wrong frame (like an echo) : I good response should be a RD...
