I have a board Nucleo WB55 and I'm configuring PWM on channel 1 of TIM2.I know is possible configure PWM Mode 1 also on channels configured as Output Compare, but CubeIDE not allow set this configuration, I think is an issue.I changed the init code w...

I have a board P-NucleoWB55 and I'm trying to acquire a signal with external clock, very similar to uart, I tried with usart in slave mode without succcess, I tried with spi slave without success.Now I'm trying to trigger a DMA transfer with a timer ...

I have a board P-Nucleo55WB and I have to receive data from usart syncronized with external clock. Is it possible?I tried to configure with CubeMX as Syncronized Slave and I see USART1_CK enabled, but this pin is not used for receive the external clo...

I have a dev board NucleWB55 and I'm trying to replicate the application BLE Cable Replacement using code generator of STMe2CubeIde 1.11.0. I configured 1 service with 2 charateristic, read and write no response for tx and read notify for rx.From an ...

I'm generating code with STM32CubeIde 1.11.0 for a STM32WB55, in my test project there is an USB CDC and BLE is enabled.When I enable BLE also IPCC must be enabled, but after HW_IPCC_Init is called usb clock is wrong so my usb device doesn't work any...

Also previous change doesn't work, I completly removed DMA and I use only interrupt on timer.So in my HAL_TIM_PeriodElapsedCallback I read GPIO with (GPIOC->IDR & 1) and I compose byte with each bit.

I have found a partial solution:HAL_TIM_Base_Start(&htim2); HAL_DMA_Start_IT(&hdma_tim2_up, (uint32_t)&GPIOC->IDR, (uint32_t)buf, 1); SET_BIT(TIM2->DIER, TIM_DIER_UDE);set size as sizeof(buf) is wrong is correct 1, so for every update 1 byte is trans...

Hello @RomainR. ,> but after that ? After that, I expect an interrupt which notify me the transfer.Input capture mode should be used when I want measure the time, rigth? I just have to sampling the pin of GPIO.Regards

Hello,I tried but without success. I solved without using CubeMX I copied crs_app.c and crs_stm.c in a file ble_uart.c and called init and works.It would be nice if STM32CubeMX could generate code for BLEUart from template.Best Regards

Hi @Guenael Cadier ,thank you for your reply. Why in the code generated by CubeMx the source code can't be external?How should I configure the baudrate when the clock is external?Maybe is better remove a part of generate code and set uart div manual...
