Hi, You can use the SPI interface and have the BS2 as a master. The BS2 then defines the clockspeed, because the slowest speed you can select on the 6811 is probably to high for the BS2. It is very simple to use this interface. See the "pink book" (...) (25 years ago, 27-Jul-99, to lugnet.robotics.handyboard)

Hello to everybody. I would like to ask if is possible to interface the handyboard with the basic stamp2 using not the RS232. Thanks beforehand. (25 years ago, 26-Jul-99, to lugnet.robotics.handyboard)

Greetings All! I was wondering if anybody out there knows of any good, relatively inexpensive, (<$350) Voice recognition hardware that is relatively easily interfaced to the handy board? Thank you very much. -Ryan Meuth (25 years ago, 26-Jul-99, to lugnet.robotics.handyboard)

(...) I remember someone saying a few months ago that if you use a 12 V battery with the HB, then the HB's built-in charging circuit won't work properly, and that 12 V batteries can initially deliver up to about 14 V, which wouldn't be very kind to (...)

I had a similar problem. In my case, the cause was underneath the board. I had not trimmed one of the components leads enough. When I screwing the board into the case the lead eventually pierced one of the wires going to my Nicad pac. My board would (...) (25 years ago, 25-Jul-99, to lugnet.robotics.handyboard)

Here is the relevant function. Note that it only works for baud rates up to 9600. void set_baud(int rate) /* For an 8 MHz clock */ { if (rate >= 300) poke(BAUD, 0xb0 | log2(9600/rate)); } You'll need regdefines.c (for the address of BAUD) as well as (...)
