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 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, Fabian PPEH.ino
vin43 posted a topic in GeneralHello all, I have been trying to understand the importance of the BSL. From the TI doc, "Programming with the BSL" I realize that BSL is used to access Memory, during the different phases of the controller. My question is: why do we need this BSL? is it required to calibrate the controller? like setting the temperature and operating conditions, before the controller takes the program execution address from the reset vector? Generally, from my understanding and usage: we used the JTAG, FET tool to download the code onto the controller, to debug the code. Then why do we need the BSL? Thanks a lot for sharing your experiences! Vin43
