Hi, I am trying to modify some of the core Energia files (main.c) so that I can initialize GPIO pins to LOW right away before Energia goes through its startup sequence. I have an LED driver connected to the MSP430FR5739 experimenter board (v1.1). The issue is, during the startup sequence (before my setup() code is running) the control pin from the experimenter board to the LED driver is active high for a few seconds thus turning the LED to full brightness. I would like to avoid using an external resistor if possible. My question is: 1. Is there a better way to initialize GPIO pins in Ener

Hi, 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
