Conecting the Homework board to the BOE board

walice_drel

I have a homework board and a BOE-BOT. In fact I just got my boe-bot in the mail today. I have it all set up and working fine. But I want to know how I can connect the homework board to the boe board so i can use it to play sound and run servos. I contacted customer support and they told me it is possible using the SERIN and SEROUT command. But I am new to all of this and could really use some help. It anyone can give me the code and a wiring diagram I would really appreciate it.

There are some diagrams in the Basic Stamp manual under the SERIN/SEROUT statements. There is also a two part Nuts and Volts article on Stamp networks (I think its #55 and #56).

I saw that but I don't know how to wire them together. It gives some examples of code once they are connected but not how to connect them. I have had my homework board for about 2 weeks and I just got my boe-bot today so i am really new to robotics so some of the examples they give i don't fully understand yet. but once i get the wiring down I can hopefully fumble threw the code till i get it right. But if anyone has a pic or diagram of how to connect them it would really really help.

Look in the Stamp Editor help file, at the bottom of the page for the SERIN & SEROUT commands. There are some diagrams there.

The connection is really simple, and should take three wires. One from an I/O pin on your BOE to an I/O pin on your homework board for 'Transmit'. Antoher wire from I/O pin to I/O pin for 'Recieve'. And one wire to connect the Vss of the BOE to the VSS of the homework board.

Then just write your program on the BOE and Homework board using SEROUT/SERIN using those I/O pins (and 9600 baud, that tends to work well).
