Re: Need CAN explanation Topic is solved

Hello Giovanni, Thanks for the help! GPIOs are available on the board, however, I do not have transceivers yet, figured it out already. I thought that if board supports CAN - they are built-in in the board. But reading board specification more carefully, it's said that I need the transceivers, so th...

Re: Need CAN explanation Topic is solved

Sorry for raising this topic again, but I can't figure out how to work with the driver. I configured the board using the .chcfg file to use GPIOB8 as CAN1_RX and GPIOB9 as CAN1_TX (Alternate mode, alternate function 9 as in datasheet) for 2 boards that I have. I am trying to make 2 STM boards commun...

Need CAN explanation Topic is solved

Greetings, I am new to the whole CAN thing and am trying to use it for my STM32F407 Discovery board project. I am looking at testhal\STM32\STM32F4xx\CAN example project and can't understand how to figure out and set-up exact pins that CAN driver will be using. From my board's datasheet I see that th...

Re: How to correctly handle USB_CDC communication? Topic is solved

Hi! Thanks for answering. I need serial over USB though. What is the disadvantage of having a buffer in my case?

How to correctly handle USB_CDC communication? Topic is solved

Greetings! I am developing a project based on STM32F406Discovery board which boils down to communication via USB with the application on the PC (connected via mico-usb to stm board). For that, I have 2 threads - for reading and writing. Writing thread is supposed to be spamming USB with a status mes...

USB-CDC for STM32F407 Topic is solved

I am new to Chibi and am trying to get the usb communication with my board STM32F407Discovery. I've adapted the following demo for this board: ChibiOS_18.2.1/testhal/STM32/STM32F4xx/USB_CDC_IAD By changing the include in Makefile from OLIMEX_STM32_E407 to ST_STM32F4_DISCOVERY and changing STM32_PLLM...
