Set analog output!

Set analog output! was created by QuiXXotic
I wonder if anyone managed to set the analog output?
According to PC config utility the analog outputpins is set to work as analog but giving them different values through a python script gives no result.

Sorry for the late response.

Try activating the analog via the console (ie serial, USB or minicom) by using the !AO cc nn command. Where cc is 1 or 2 and nn the value from 0 to 4095.

Yeah ive tried that and its working...

But a simple python script like
import rioboard

rioboard.Init()
rioboard.WriteAnaOutput(0, 0)
rioboard.WriteAnaOutput(1, 2700)

has no effect. No errors either but no effect on the output. Executing other scripts using digital i/o´s works flawless. If i give them a value in console i cant get the to zero by script either.

We'll have to look into the code. Pls stand by.

If you are in a big hurry, you can always use the serial connection between RPI and RIO and send the string like !A0 1 1234

For this big project i would like to use a solid solution. Spent over a half year fulltime developing a quite extensive program using this rioboard to control a robot wich is communicating with and android app. But now its all falling apart due to not being able to control some status led with the analog outputs :P

Hello QuiXXotic,

Thanks for being so patient waiting for the fix.

We have the release candidate that includes a solution for an Analog Output issue.

We are still in progress of testing/verifying this version but in case it is blocking you and you would be willing/interested to test the version early - drop me an email at olegATroboteqDOTcom.

Regards

Well, it's been 3 months since the software was in testing, as I can see. Still no working Analog Outputs? I am trying these since the PWM outputs do not work yet, only to find out the Analog Outputs aren't working yet either?
Help me out here guys, I really have to get this AGV up and running! How do I get the analog output to work from Python? Can I send a serial command from Python? If so, how?!

Sorry to inform you that nothing works really but regular inputs/outputs. I got my hand on a firmware version with somewhat working analog output. One output worked not the other one. Also bought this due to it had it all and that was 15months ago....and i got four of theese...just lying around useless for now due to nothing really works. I constructed my own expansion card with I/Os, pwm, encoder inputs, ADC etc. instead cause i gave up on this. I think it is discountinued btw. If it was sold in my country i would demand money back due to false advertising.....
