Thread: eyeR Interceptor PRO for standalone use, or FusionBrain addition

Can your PWM units be used with other microcontrollers, like say an Arduino? How is the documentation coming on this unit?

Thanks
Hans

The eyeR has onboard Rx/Tx port, connecting these two pins directy to the arduino's rs232 port will allow you to control all the eyeR features and ports.

The manual is progressing but not done yet, a few days and it will be done.

So what are you planning with the arduino?

Actually, I was specifically interested to know if your external DC motor control PWM module could be used with the Arduino, but good to know that an EyeR and Aurduino could talk to eachother. I have a Seeeduino Mega from a different project, and need to add some heavy-duty pwm control (electric waterpump).

I do have a question for you. My climate head adjusts the temp through a pot that runs a range of 200 to 1200 ohms between 60 and 80 degrees (pot is clocked to start at 200 and limited in either direction by mechanical cam). How would your recommend controlling this variable resistance with the EyeR? I havent found a digital pot that would work, so curious if you have any ideas.

Thanks
Hans

The FET module accepts low-level 0/5v input, so it should work when connected to any microcontroller output as long as the micro runs off 5v.

I'm suprised a digital pot didn't work. Maybe you could try connecting a digital pot to the input of an op-amp (setup as a voltage follower) and then use the output of the amp to driver the temp control circuit.

I hope this is not to technical and makes some sense

The eyeR can't control digital pots as yet, but it is possible with some software.

just ordered, any progress on the manual??

The manual is progressing and I will make sure its ready before you receive the eyeR

Thanks for you patience.

Manual and drivers are now available for the eyeR PRO. See first post for details.

The Firmware upload instructions aren't included in the manual yet but I will add it in as soon there is a new firmware update.

Latest firmware has already been loaded so the eyeR is good to go.

This looks promising. Does it have any capabilities the Fusion Brain doesn't? Specifically, can it emulate a rheostat (variable voltage output)?

This is my intention:

xbstw, the temperature control is the final piece to the puzzle I haven't figured out yet. At first I thought it would be easy, since the heat blend door is moved by a servo controlled by a logic board.

The logic board tells the motor how far to open the blend door based on a voltage input from the temperature dial. It's basically a rheostat (potentiometer) that sends 20 or so different voltage levels to the logic board.

Getting Fusion Brain to emulate the different voltage outputs is the final piece of the puzzle.

stonestatue, the interceptor supports 2 servo's, so it looks like you could bypass the logic board and connect strait to the heat blend servo.

i always try to simplify systems as much as possible, but this may not be possible in your case, but it's worth trying.
