Analog-to-Digital conversion in BS Discovery Kit?

Dear members, I need an analog input (output of current sensor for DC motor control). Would you please let me know if there is any ADC built in already in BS2 Discovery Kit or I need to have my own ADC?

The BS2 has no ADC, but it can interface with an ADC IC.

Parallax sells the MCP3202,3204,and 3208 chips for 2, 4, and 8 channel ADC needs.

If you need to do relatively coarse slow ADC, you can do it with a Stamp using the RCTIME statement. There's a section in the "app-notes" page on the EMESystems website that deals with this, mostly for battery level monitoring.

Parallax also sells the handy-dandy 1 channel ADC0831 for $6: http://www.parallax.com/StoreSearchResults/tabid/768/txtSearch/adc0831/List/0/SortField/4/ProductID/245/Default.aspx
