Hi All,
I posted this a while ago, but there have been some updates, plus a video, and code that works well-ish.
I have finished the first stage of my does-a-ton-of-stuff arduino project, which right now is just a handheld wireless spectrum analyzer, multimeter and oscilloscope. Basically, it is a red cardboard sparkfun box breadboard (box broke) with an LCD (http://www.sparkfun.com/products/10168) and a button on the front . Inside, there is an arduino, a sparkfun logic level converter (i was too lazy to wire up the mosfets myself http://www.sparkfun.com/products/8745 ), a cywm6935 radio (AGH 2mm pins!! http://www.mouser.com/ProductDetail/Cypress-Semiconductor/CYWM6935/?qs=eg8mrW3YyI52eYLXBaGRLQ%3D%3D ), and these to connect to it: http://www.sparkfun.com/products/8732. Eventually, i want it to be a nice portable tool that prevents me from having to buy many seperate tools or an expensive multi-function one like the dso nano (but if I had $90 believe me, i would buy it in a nanosecond), plus i made it, which is always fun. The code is below, any ideas for what else i should make it do?
Heres the video:

and the (lengthy, poorly documented) code is coming in the next few posts.
Thanks!

hello,

  I'd like you to describe the operational buttons. Is it two? Is it first interrupt "PWM pin2" is zero interrupt and on this pin connect the input wave, receive signal? Furthermore, the "MODECOUNT 5" is digital pin 5? on this pin connect the switch button?

  Is it right this change,

   /*
    unsigned char s = RADIO_RSSI(n);
    */
   
    unsigned char s = analogRead(n);

to read from analog "PWM pin 2" -zero interrupt a wave???
