The stack supports the following MCUs
- **Nordic:** nRF52840
- **NXP:** LPC11Uxx, LPC13xx, LPC175x_6x, LPC177x_8x, LPC40xx, LPC43xx
- **MicroChip:** SAMD21, SAMD51 (device only)
- **NXP:** LPC11Uxx, LPC13xx, LPC175x_6x, LPC177x_8x, LPC18xx, LPC40xx, LPC43xx
- **MicroChip:** SAMD21, SAMD51
- **ST:** STM32F4
[Here is the list of supported Boards](docs/boards.md)
## Compiler & IDE
The stack is developed with GCC compiler, and should be compilable with others. However, it requires C99 to build with. Folder `examples` provide Makefile and Segger Embedded Studio build support.

##### dcd_set_config
Called when the device received SET_CONFIG request, you can leave this empty if your peripheral does not require any specific action.
##### dcd_remote_wakeup
Called to remote wake up host when suspended (e.g hid keyboard)
#### Special events
You must let TinyUSB know when certain events occur so that it can continue its work. There are a few methods you can call to queue events for TinyUSB to process.
