fabo9573 got a reaction from abecedarian in Msp430G2553 draws significant current at start up
Hi spirilis,
Ok, i just commented out the wrong thing! Now it works! Thank you so much! Really appriciate this amazingly fast help!
Just shocked how low the consumption really is. I did a lot of things before with the Cypress PsoC (1 and 4) but the MSP is just way better in power consumption.
Not gonna be the last project!
Thank you again,
Fabian

Hi,
Thanks for your quick reply, really appriciate that. I don't use any regulators, i disconnetcted the programmer with the jumpers J3.
I power it from a big cpapcitor, see the attached picture. 1000

No most likely the Energia core polling to check for the presence of the LFXT1 32.768KHz crystal. Is that soldered on, or could you add it?

Probably an initial current surge used by the regulators on the LP. How are you powering it? You can use the J6 3.3V header on the LP to power the 2553 externally
Also.. a pic of the TEG would be nice to see!
