/**
|
|
* @brief Debug output via UART.
|
|
*
|
|
* Configuration:
|
|
* STA_DEBUG_SERIAL_ENABLE: Enable module
|
|
* STA_DEBUG_SERIAL_FORCE: Ignore debug defines and always enable output
|
|
* DEBUG: Enables output when defined
|
|
* NDEBUG: Disables output when defined (overrides DEBUG)
|
|
*
|
|
* The `sta::DebugSerial` instance must be provided.
|
|
* NOTE: Include this header before the definition because
|
|
* the default internal linkage of const namespace variables
|
|
* will cause undefined reference errors otherwise.
