You can expand the functionality as needed: perhaps you need an rx interrupt. The simplest form of calling code might look something like: usart_result_t result Īnd so on, this for the simplest form of busy-wait polling. stm32_usart.c implements these functions. Usart_result_t usart_receive (uint8_t* data, size_t buf_size, size_t* data_received) Īnd that's pretty much it. Usart_result_t usart_send (const uint8_t* data, size_t size)

* pick parameters to suit whatever functionality you wish the driver to include here, Usart_result_t usart_init (uint32_t baudrate_hz. Typedef enum // some error handling type for this driver If you have no such special requirements, then the additional HAL is just bloat and you should implement the simplest form of a UART driver: // stm32_usart.h That's where "opaque types", function pointers and all that comes in - only then.

If so, it would make sense to wrap the UART in an additional HAL so that your serial library code becomes portable between different microcontrollers.

The only reason why you'd want a HAL between the application code and the driver is if the application is some sort of serial library: suppose you are implementing a printf-like function, an UART error logger or bootloader etc, something that you want to re-use in multiple projects. Normally there is no need to have a HAL in between that driver and the application, because UART is pretty straight-forward and simple. Normally you would have something like stm32_usart.h + stm32_usart.c making up the actual driver. HAL_USART_RX() // assuming data is stored in one of the struct members Get data via UART (calling application API) I have heard different things regarding how application code should have no clue whatsoever about the driver APIs, and read up an article the other day that you could decouple the sensor code from HAL driver code using function pointers but not sure how I could do that here, and if that will decouple it considering I'm still passing a reference to USART_Handle struct that contains info like baudRate, parit圜ontrol, wordLength, reference to USART_TypeDef etc. So I have main.c, sensor.c (application file that uses UART layer), hal_usart.c (which is the driver file).

Help would be much appreciated.So I'm writing drivers for UART on STM32 and even though I kind of have an idea on laying out the structure, I'd still want to clarify prior to implementing, and also considering how essential it is to keep the code clean and organized. I blocked all the day on this, spending a lot of time trying things, but nothing worked.

How to correct this? I have not found where/how the folders Driver>BSP, CMSIS and STM32F4xx_HAL_Driver are defined (in project properties ?), and how it can happen that for a project, not all. On the project STM324x9I-EVAL_USBD-FS, compiles, and stm32f4xx_hal_pcd_ex.c does appear in the Project>Drivers>STM32F4xx_HAL_Driver folder. So the path seems OK as I have the majority of the hal source files, but a specific one that I need is missing.

A lot of stm32f4xx_hal_xxx.c are here, but the one I need seems to be missing. I followed the cascade of includes and it seems OK, but stm32f4xx_hal_pcd_ex.c does not appear in the Project>Drivers>STM32F4xx_HaL_Driver folder.

Undefined reference to `HAL_PCDEx_SetRxFiFo’ usbd_conf.c /STM324xG-EVAL_USBD-FS/Application/User line 363Ĝ/C++ Problem I have issues to adapt the different path from one project exemple to another project. To develop my application, I have to use some USD device audio application examples developped for one of the stm32F4 Eval boards, and adapt that example to my STM32F4_dicovery.
