you normally only need "volatile" if there are concurrent reads
& writes from tasks and/or interrupts to variables. All reads
and writes up to word size (= 2 byte = int) can be considered atomic
on the PIC18, and can_soc will only be written to by the IRQ and
read from by the high level functions, so you normally won't need
"volatile" on the can_soc variable alone.<br>
<br>
New guess: you said you're using filter #2 for 0x30* msg ids, and
changed my can_soc reader -- now, my can_soc reader happens to be
located in poll0(), which is assigned to buffer #0 = filters #0
& #1. For filter #2 you'd need to use buffer #1 and accordingly
poll1(). Did you change the code accordingly for that setup?<br>
<br>
"Internal" means "in the OVMS module". If your car does not provide
GPS, you can use the OVMS GPS by enabling both the compiler switch
"OVMS_INTERNALGPS" and the net_fnbits (exactly as the twizy module
does). You'll also need an active GPS antenna, a simple one will do
perfectly, but take care it will run on 3 V (some older/special ones
only run on 5 V). Also be aware that the internal GPS will raise the
OVMS current needs to about 110 mA = about 34 Wh/day or 1 kWh/month
-- should be no problem with frequent car use & charging though.<br>
<br>
SMS commands and replies do not go through the OVMS server but are
exchanged directly between mobile phone and OVMS module. The server
is solely responsible for the IP connectivity (MSG commands).
Primary tool for debugging is the DIAG port and mode, please read
"docs/Firmware-Development.odt" for instructions on how to use that.<br>
<br>
The currently available Android App does not yet support arbitrary
MSG commands (I think the iOS one does, but can't test that). If you
want to send your own MSG commands to your live module, you can also
use the perl client for that:
<a class="moz-txt-link-freetext" href="https://github.com/markwj/Open-Vehicle-Monitoring-System/blob/master/server/client_app.pl">https://github.com/markwj/Open-Vehicle-Monitoring-System/blob/master/server/client_app.pl</a><br>
<br>
You need to change the passwords (line 11+12) and the car id (line
41 "TESTCAR") in the .pl file. Then you can send a command like
this, for example before entering the receive loop:<br>
<br>
my $encrypted = encode_base64($txcipher->RC4("MP-0
C32,RT-GPS-Log"),'');<br>
print STDERR " Sending message $encrypted\n";<br>
print $sock "$encrypted\r\n";<br>
<br>
This for example will send command 32 (C32 = retrieve historical
data) to the module with argument "RT-GPS-Log". The result will be
printed on stdout by the receive loop.<br>
<br>

experiences with CAN bus, and have learned the lesson to test
where the values are and take it from there. This is why I
actually used the car_linevoltage and car_charging current
variables and put the can_buffer bytes 0,1,2,3 in them to see
what am I getting... and the result was zeros. While the 4 and
5 are getting the old value.</div>

<br>
I don't know PCAN, but the CAN byte numbering normally
begins at 0 on the left, so 0e in your example is
can_databuffer[2] and 7d is ...[3].<br>
<br>
If you get 0AB2, that would be [6][5] = your initial
code?<br>
<br>
Btw: we could solve variable name conflicts between
vehicle modules by introducing some namespace prefix
(replacing "can_") like Mark already did for the
functions. I'd shorten that for vars to e.g. "vrt_" for
"vehicle renault twizy", accordingly "vtc_" for the
Think and so on. OK, Mark?<br>
