Detailed Description

Hardware Abstraction Layer (HAL) is an abstraction layer, between the physical hardware and the tinyusb stack. Its function is to hide differences in hardware from most of MCUs, so that most of the stack code does not need to be changed to run on systems with a different MCU. HAL are sets of routines that emulate some platform-specific details, giving programs direct access to the hardware resources.

Function Documentation

tusb_error_t hal_init

(

void

)

Initialize USB controller hardware.

Returns

tusb_error_t type to indicate success or error condition.

Note

This function is invoked by tusb_init as part of the initialization.

static void hal_interrupt_disable ( uint8_t  coreid )

inlinestatic

Disable USB Interrupt on a specific USB Controller.

Parameters

[in]

coreid

is a zero-based index to identify USB controller's ID

Note

Some MCUs such as NXP LPC43xx has multiple USB controllers. It is necessary to know which USB controller for those MCUs.

static void hal_interrupt_enable ( uint8_t  coreid )

inlinestatic

Enable USB Interrupt on a specific USB Controller.

Parameters

[in]

coreid

is a zero-based index to identify USB controller's ID

Note

Some MCUs such as NXP LPC43xx has multiple USB controllers. It is necessary to know which USB controller for those MCUs.
