  • Arduino High speed Oscilloscope with PC interface

    Hi JurisP1,my 238KHz code is the fastest internal ADC version I have written. It uses a mega and a colour touch screen display by sain.I have written code to run at 1.2 MHz. using the parallel interface on the ADC TLV571 chip.As a starting point, the code and details in this instructable work well.Regards,David

  • Arduino High speed Oscilloscope with PC interface

    Following limited interest I have placed a copy of my 238Khz oscilloscope software at:http://www.davepatterson.me.uk/public/Oscilloscope...The code has adequate annotation. I offer it without support.The required hardware:Arduino mega 2560Sainsmart 3.2 inch lcd and shield: $24.99 http://www.sainsmart.com/sainsmart-3-2-tft-lcd-di...A sd card to fit the sainsmart shield (less than 2GB)A good quality potentiometer between 5V and ground with the wiper to analogue 4. Any value that will not pull a large current. (This sets the trig level)Any signal conditioning circuit of your choice- connected to analogue 0.David
