I ordered a smart power2 for the second time due to this problem. I have been using the smart power2 monitoring through scripts a xu3 board. First, I want to say that I strictly followed all instructions on https://wiki.odroid.com/accessory/power ... martpower2.
The first time the smart power2 burnt down, I updated the firmware and increased the sample rate to 10Hz (viewtopic.php?f=86&t=31395&p=261157&hilit=usb#p261157),
And I implemented a telnet client to threat the power data. I have used this scenario for some days until the one morning, I turn it on, and the power supply unit LED flashed, and the smart power2 smoked. At the moment, It was not plugged to the xu3.raditya160053 wrote: ↑Wed Jun 12, 2019 11:39 amHi, the report will take a little longer still. but for smartpower2 with ubuntu, I just cloned their update firmware(v1.4) code, changed one line that corresponds to time/frequencyodroidpower wrote: ↑Wed Jun 12, 2019 8:16 amHi any updates on the complete report on how to change the sampling rate?
I plan on doing the same, but with an Android OS. I saw in the wiki something that says it doesn't work with anything newer than Android 2.2?
All of the Android images are 4.4 +1 here means, sampling every 1 ms(by default it is 1000).
Code: Select all
timerId = timer.setInterval(1, handler);
after the change I built it in arduino IDE and uploaded it to the smartpower2 via USB cable.
Instructions to upload firmware are given here: https://wiki.odroid.com/accessory/power ... rduino_ide
I bought a new one. I did the same procedure as the first time, update and increase the sample rate. I have been using for some days. This time, I was planning to implement a script to get the power information on xu3 through USB cable. I used the 'screen' command to make sure the xu3 was receiving information through USB cable. It worked, it showed the power information on my terminal. Then, I turned off the smartpwer2 from the turn on/off button and unplugged the power supply. A few minutes later, I turn it while the power cable was plugged to xu3 and USB cable was connecting both. So, the power supply unit led started to blink, and immediately I unplugged. I tried to turn it on again, without success. I know that I am not the first person with this problem:
I requested the distributor to replace it since I ordered less than 15 days ago. I want to avoid this problem to repeat. Before, I would appreciate some help to identify what it is causing that.
