BS2p works with board of education
Archiver
Posts: 46,084
After switching in a newer battery and executing the compile command
a couple of times, the program compiled and was burned onto the BS2p
stamp via the Board of Education. I think my battery voltage in my 9V
was too low.
Now I have a new problem. I'm hooking the SOUT line of my BS2p to
the transmit line of an LCD. I'm serially sending out ascii code to the
LCD using the debug command. I'm sure that the LCD transmit line can
interpret ascii code similar to the way the computer displays debug
command statements in the debug window. The reason I'm sure is because
I can see the statements on the LCD if I run the same program on the BS2
stamp. However, if I try to run the same program (with file suffixes
changed of course) on the BS2p LCD displays a couple of numbers and some
crazy characters I have never seen before.
I believe the reason for this is the Baud rate that I am sending my
serial information out at. According to the Basic STAMP manual (v2.0),
the debug command is supposed to send out data from a debug command at
9600 Baud for both the BS2 and the BS2p. The LCD is supposedly set to
receive information at 9600 Baud. My hypothesis is that the BS2p is
transmitting data at a little higher rate than the BS2. If that is
true, the BS2p could be transmitting a little out of spec from the LCD's
expected receiving Baud rate. Any information on the specific transmit
rate of the BS2 and the BS2p stamp with respect to the debug command
would be greatly appreciated.
