Sample code for MCP3204 ADC?

Martin Hebel · 2010-04-23 13:19

Can someone post some sample code to read the MCP3204 using the MCP3208 driver by Chip in the installed propeller tool?

I think we are using it right, but getting 0 out.

Thanks!

Martin, I came up with a couple demos for that chip over in the Object Exchange.

Thanks, but that's a totally different driver than I want to use.

I don't know if this will help you, but here is the PropBasic code I use to read the MCP3204.

TASK ReadADC ' Reads CH0 of ADC. Puts value in HUB long "EFCVal".
 
  Value  VAR LONG

 
  HIGH ADC_Cs
  LOW ADC_Clk
  PAUSE 5
  DO
    LOW ADC_Cs        ' Enable MCP3204
    PAUSEUS 100
    SHIFTOUT ADC_Din, ADC_Clk, MSBFIRST, %11000\5 ' Select CH0, Single-Ended
    SHIFTIN ADC_Dout, ADC_Clk, MSBPOST, Value\13  ' Read ADC
    HIGH ADC_Cs       ' Disable ADC
    LOW ADC_Clk

    WRLONG EFCVal, value
    PAUSE 1
  LOOP
ENDTASK

Use BASIC on the Propeller with the speed of assembly language.

lol, thanks Bean, but no, doesn't help since it isn't spin and not using the driver we are using. Thanks though.
