//! This is a debug utlility that makes it easy to toggle gpios to debug paths which are very
|
|
//! sensitive to timing.
|
|
//! To use it simply:
|
|
//! 1) Call debug_gpio_init() before you want to track things
|
|
//! 2) Call debug_gpio_toggle() to flip the gpio state
|
|
|
|
//! Initializs DEBUG_GPIOs defined in board config and drives them all low
