TinyUSB is an open-source cross-platform USB Host/Device stack for embedded system.

TinyUSB is an open-source cross-platform USB Host/Device stack for embedded system. It is designed to be memory-safe with no dynamic allocation and thread-safe with all interrupt events are deferred then handled in the stack's task function.

## Supported Boards ##
|
||||
The board support code is only used for self-contained examples and testing. It is not used when TinyUSB is part of a larger project. It is responsible for getting the MCU started and the USB peripheral clocked withminimal of on-board devices
|
||||
- One LED for status with different blink pattern
|
||||
- One Button to get input from user
|
||||
- One UART optionally, mostly for host examples

## Add your own board

|
||||
If you don't possess any of supported board above. Don't worry you can easily implemented your own one by following this guide as long as the mcu is supported.
|
||||
|
||||
**Guide to implement a new board is coming soon** ...
|
||||
- Create new makefile for your board at `hw/bsp/<board name>/board.mk` and linker file as well if needed.
|
||||
- Create new source file for your board at `hw/bsp/<board name>/board_<board name>.c` and implement following APIs
|
||||
|
||||
### Board APIs
|
||||
|
||||
#### board_init()
|
||||
|
||||
Is responsible for starting the MCU, setting up the USB clock and USB pins. It is also responsible for initializing LED and button pins.
|
||||
One useful clock debugging technique is to set up a PWM output at a known value such as 500hz based on the USB clock so that you can verify it is correct with a logic probe or oscilloscope.
|
||||
Setup your USB in a crystal-less mode when available. That makes the code easier to port across boards.
|
||||
|
||||
#### board_led_write()
|
||||
|
||||
Set the pin corresponding to the led to output a value that lights the LED when `state` is true.
|
||||
|
||||
#### board_button_read()
|
||||
|
||||
Return current state of button, a `1` means active (pressed), a `0` means inactive.
|
||||
|
||||
#### board_millis()
|
||||
|
||||
The function returns the elapsed number of milliseconds since startup. On ARM this is commonly done with SysTick or Timer. This provide examples a way to measure time to blink LED or delay properly. It is only required when run examples without RTOS `CFG_TUSB_OS == OPT_OS_NONE`.
|
||||
|
||||
#### board_uart_read()
|
||||
|
||||
Get characters from UART peripheral.
|
||||
|
||||
#### board_uart_write()
|
||||
|
||||
Send characters to UART peripheral.

Feel free to skip this until you want to verify your demo code is running. To implement, set the pin corresponding to the led to output a value that lights the LED when `state` is true.
