Task ID

Task priority

Completion callback URL · optional

After the device completes, CServer posts the command ID, status, result code, and response bytes to this URL. The default address feeds the callback handler displayed on this page.

Source has not been assembled yet. Opcode is fixed at 0x4850 (HPVM_LOAD_AND_START).

Variable ID · timer_delay

Program variable

Selecting a name fills its numeric HPVM resource ID.

Variable U32 value

Variable setting lifetime Save on board across power cycles

Input ID · run_enable

Runtime controls

Runtime commands remain numeric on the wire. The HPL names timer_delay and run_enable both compile to resource ID 4. Variable settings are persistent by default; clear the box for a temporary value that is lost on reboot.

Compiled payload sent to device (hex)

The first 8 bytes are the task envelope. The remaining bytes begin with 4850564D (“HPVM”) and are the canonical .hpb package.

The browser compiles this source into the canonical HPVM package, adds the task envelope, then submits it to the durable command queue. The device still performs its own package verification before execution.
