Detailed Description

A simple HID (Human Interface Device) scope

  • Up to 6 channels of float data is transmitted in a single HID message (64 byte)
  • Theoretical maximum samplerate of 1kHz
  • Data can be parsed using a client-side server like NodeJS.

Example: 

 #include "mbed.h"
 #include "HIDScope.h"

 HIDScope    scope(2);
 Ticker      scopeTimer;
 
 AnalogIn    a0(A0);
 
 int main()
 {
   
   scopeTimer.attach_us(&scope, &HIDScope::send, 1e4); // Send data at 100 Hz
   
   while(1){  // Generate some data
       scope.set(0, a0.read());
       scope.set(1, a0.read());
       wait_us(1000);
   };
