Problem with CRC dates with TL2100 #111

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
The Christmas holiday seemed to be a good moment to setup a Raspberry Pi to log 
my PV data to pvoutput.org. I have been using an android tablet with Sunny 
Solar Log so far. I got quite far with the setup but now experiencing a problem.

Inverter: SMA 2100TL (installed 10-12-2012)

At first I thought it had to do with the Inverter codes. I used USBScoop to 
find the codes for my inverter. Using the instructions in the wiki I found the 
numbers. Assuming I did the right thing the codes are:

Code1    0x0e
Code2    0x0c
Code3    0xdd
Code4    0x3a
I entered the values in invcode.in.

What steps will reproduce the problem?
1. smatool -v

What is the expected output? What do you see instead?

Small update:

I got it working now bij disabeling the break in the smatool.c

                                         if( idate != prev_idate+300 ) {
                                            printf( "Date Error! prev=%d current=%d\n", (int)prev_idate, (int)idate );
                                         //   error=1;
                                         //   break;

I do not now what the exact consequences are but it does upload to PVoutput.org 
now!
