Emic2 & EasyVR

prodigyrick

Has anyone figured out how to get these two to work together without locking up easyvr in the process?
I used one of the examples for easyvr, added a led to control on or off by voice, and added code for emic2 to repeat the valid words. After emic2 finishes speech, easyvr seems to be stale. Not sure whats doing this and I don't know enough about serialization to fixit. I tried playing around with what I learned off google in serialization but I had 0 success.

Ideas?

You have to be careful when using an EasyVR with the Emic2. The EasyVR will hear what the Emic2 says and take it as a command. You need to disable the EasyVR whenever the Emic2 talks. I know there's a command to send to the EasyVR to disable it. I think you want to send the EasyVR the sleep command with a zero parameter so it will only wake when it receives another character from the microcontroller.

Which microcontroller are you using?

I haven't used these devices with an Arduino but I'm pretty sure in order to use both the Emic2 and the EasyVR, you need to use a software serial driver (UART) with one of them. You can use the the hardware UART with one device and a software UART with the other. I'm not sure if you'll have the option of using a third UART to send debug statements to a terminal window but I doubt this is an easy option to include.

I'm heard of hardware serial multiplexers but I haven't used these myself.

As long as the signals are logic levels (not +-12V rs232) you could use a cd4052 as a hardware multiplexer to switch the arduino Rx and Tx lines to one of four other chips provided you have 2 spare I/O lines to use as selects.

I wish I knew how to decipher what you just said. What do I need and wheres an example of this solution. lol
