my name is Fabian an im recently working on an MSP430 project with the Launchpad MSP-EXP430G2 and Energia 0101E0017.
I have an TEG Harvester and want to run the MSP that sends data via a NRF24l01 module.
Everything works great, current is really low in working and in sleeping mode.
But now the problem:
When i apply power to the chip (3,3V) it draws significant current for about 2 seconds. Then it starts working normal and the current drops and stays low as long as you don't remove the supply and start again.
This is really bad for energy harvesting applications, because you need a much bigger harvester just because of that power up current that just happens sometimes.
Is there a setting for the startup time?
Please see my attached code.
Thank you so much,
