LED Signals

 Top  Previous  Next

Your "EM202" device (target) can be in one of two main states:

•RUN: the Virtual Machine is executing your BASIC application.
•PAUSE: the Virtual Machine is NOT executing an application.

When your application is running, the Green and Red Status LEDs are under its control (see the Pat Object).

When the application is not being executed, the target displays one of the following LED patterns:

 

tide_LED_no_firmware

Firmware problem (fast green-red-green-red). No firmware (TiOS) file loaded, or incorrect firmware file, or firmware file corrupted. This is what you get if you upgraded your device with incorrect firmware file.

tide_LED_no_app

No application file in memory (red LED blinking fast). TiOS firmware loaded but there is nothing to execute (or application file is corrupted).

 

tide_LED_good_app

Application file in memory, not running (green LED blinking fast). This is the pattern which appears when program execution is paused (in debug mode).

tide_LED_no_ram

Insufficient RAM (both red and green LEDs blinking fast and together). Application file is loaded, but cannot run due to insufficient RAM (memory for storing variables) available on current the device.
