spirilis 1,265 Posted May 5, 2016 Share Posted May 5, 2016 F5529 doesn't support EnergyTrace so I can't optimize the performance of the sensor node. That is one of the reason why I want to migrate to FR6989. Second reason is that in general compact design is more reliable i.e. LCD is part of LP board and I guess it may consume less power. what @@abecedarian said... The power consumption of the LCD entirely depends on how fancy an LCD you use. The other consideration is that, since you only need the LCD for occasional "configuration" purposes, the board housing that LCD can provide power for itself and/or power (or recharge) the WSN board. Using level shifters in the bus interface the former option, i.e. the LCD board power itself, is easily doable. abecedarian 1 Quote Link to post Share on other sites

BRey 22 Posted May 6, 2016 Share Posted May 6, 2016 Rei Vilo has an article describing using a FET with EnergyTrace to analyze a launchpad which doesn't have it, could you use this to optimize the F5529?: http://embeddedcomputing.weebly.com/ultra-low-power-with-msp430.html B Quote Link to post Share on other sites
Adnan 2 Posted May 6, 2016 Author Share Posted May 6, 2016 Maybe knowing more about what you're trying to accomplish could help us help you? I designed a new MAC protocol and want to evaluate it's performance in real world. The purpose of this protocol is to maximize the lifetime of the sensor node. Quote Link to post Share on other sites
Adnan 2 Posted May 6, 2016 Author Share Posted May 6, 2016 In datasheet, the minimum power consumption of CC1120 in sleep mode is less than 10 uW and about 3 uW for FR5969. So, the expected power consumption is about 20 - 100 uW. During the operation of FR5969+CC1120 the minimum power consumption recorded is about 3 mW. I can't figure out the reason behind this difference. Quote Link to post Share on other sites
