Measure a board's current draw, for battery life

Running current read through the debug probe, even on a board with no meter of its own.

Some pieces of it have run. There are no recorded steps for this project, so this page does not give any.

What exists:

LAUNCHXL-F2800137: 35.4 mA running CoreMark at 120 MHz and 2.59 mA in STANDBY, read through an MSPM0 L1306 EnergyTrace probe; coin-cell life not measured

You would need the board, plus MSPM0 L1306 LaunchPad development kit.

Errors and fixes: LAUNCHXL-F2800137.

What to build next

How fast a chip reacts to a signalHow many cycles from a signal to its handler, and one motor-control step timed

Dim an LED or move a servoThe LED dims up and down, or a hobby servo swings

Spin a brushless motorThe motor spins from a LaunchPad and a plug-on driver board, then runs closed loop on TI's FOC

Every build. The code for all of them is in the GitHub repository.

Evidence and limits35.4 mA running CoreMark at 120 MHz and 2.59 mA in STANDBY on the F2800137, read through an MSPM0 L1306 EnergyTrace probe; no coin-cell life figure was measured. Ran on 1 board. Results, sources, timing and limits.

Status	What was tried	Result
	Why does EnergyTrace on the TI LP-MSPM0L1306 not work on a Mac in CCStudio 21, and can it be made to? MSPM0 L1306, 2026-10-06	Two functions in the IDE's code switch trace off on macOS, with the comment "not supported". TI's Mac trace server library cannot load as shipped, because of a path from TI's build machine and a Linux-style search...
Works	Can the TI LAUNCHXL-F2800137, which has no EnergyTrace, borrow the LP-MSPM0L1306 probe to measure its chip's current? LAUNCHXL-F2800137, 2026-10-07	Works: two wires from the MSPM0 L1306's EnergyTrace probe to the chip side of the C2000 board's JP2 jumper make it the meter. Above the HALT reading: 35.4 mA running CoreMark at 120 MHz, 2.6 mA in STANDBY. The C2000...
