How to run HRTIM DMA to GPIO?
Hey Community,i am working on a parallel output interface. I want to realize it with GPIOE and all of the 16 Pins.To Generate an output i used TIM2 to trigger DMA1 so far so good. The Output is working with memory to peripheral. The DMA is copying th...
Hi, i would like to know which IDE can be used to program BlueNRG-2 series MCU and the part number is STEVAL-BCN002V1B. I tried using STM32Cubemx IDE but there is no option to select BlueNRG under MCU selection options. Please, can anyone tell me. Thanks
And did anyone work on STEVAL-BCN002V1B blue tile development kit? If yes please let me know.
Use Timer DMA burst to update *another* timer
Hi all!I have a use case that seems like it's not supported. I have one timer (TIM3) running PWM with multiple channels, I would like to use a DMA burst to update the duty cycles of all channels and I have successfully done this by triggering on the ...
I2S Tx Complete callback is never called while the TX Half Complete callback is.
Hi There,Im currently trying to move some basic I2S code over from a STM32F407 to a STMG030K8. All the code is doing is using a circular DMA mode to transfer a buffer. As with any circular mode transfer, Im wanting to fill the buffer with new data in...
Can i use GPIO pins in modbus.h and modbus.c?
Hi, i want to use GPIO pin in Modbus.h and Modbus.c file using stm32f103. But even if I mention header file in my Modbus.h the code is not working. it shows error.stm32f1xx_hal_gpio.h is the header file I included in Modbus.h. HAL _ GPIO _ Write Pi...
LPUART1 is not working in STM32L4R5ZI development kit?
Hi,I am new to ST controllers, I have an STM32L4R5ZI nucleo development board. By using STM32CubeMx I generated code for LPUART1 and in the main.c in the while loop I have added a "printf" statement, but I am not seeing anything on the UART terminal ...

I want to try gdbserver and openOCD on CLI so as to compile and debug STM32 MCU Firmwares via CLI and to get an understanding of their work. But not able to get enough resources on the net for their installation as I am windows user and resources ava...
How to store 8 bits register value from Modbus to different variable
Hi, I want to store 8 bits of data coming from my Modbus in a different variables in the form of 1's and 0's using stm32f103.I have done code like , the bits i have sent is 101101101 sent by Modbus is storing in my holding register [1] in the fo...
STM32L071 MCU LPUART use LSE to configure BaudRate 9600. Actual BaudRate is 8300 or 11000.Error islarge. LSE is 32.768kHz ,One cycle is 30.517 us。One cycle of BaudRate 9600 is 3.4 times of LSE。But LSE frequency division can only be an integral multiple。
So,LPUART can not use LSE to configure BaudRate 9600?
