Hi, has anybody ever used the ADC to drive a button? Now we are going to use 4 ADC ports to connect them with buttons. Has anybody got an Example? Thanks w. Pethe PS: Then I can use some GPIO Pins for output. |

Why not? Use a pullup resistor and ground with a button press. That
should be easy to do. -----Original Message----- From: wpethe [mailto:] Sent: Wednesday, January 16, 2002 10:36 AM To: Subject: [motoroladsp] Use Button at ADC???

You might try looking at the FAQ's regarding the DSP56800's ADC unit for ideas. Simply goto: http://e-www.motorola.com/cgi-bin/faq.cgi Simply select DSP56800 under the 16-bit path DSP's and then do a search for the category "A/D Converter Module". The FAQ's contain several examples of using the ADC in its different modes.
