No LED response from Traffic light program

Good Afternoon,
I recently put together the CH3-R hexapod. As the title suggests, I have not been able to get a response from the A,B, and C LEDs on the Bot Board II with the Traffic Light example program. I have tried both with and without the A,B, and C jumpers, and I’ve tried with the baud rate on the SSC-32 at both 38.4k and 115.2k. I have the serial cable plugged into the BBII, and the program seems to compile and download without error. The BotBoard II just doesn’t do anything. Has anyone run into this before? I’d appreciate a nudge in the right direction. Thanks in advance.

Hi,

Which traffic light program? If you are talking about the traffic light program that is part of the Basic Micro Manual?

If so there are two issues with the program. The first was it assumed IO pins 0-2 were the LEDS, where on the Bot Board 2, these LEDS are on pins P12-P14 (or older Atom Bot Boards on pins P4-P6). Also the LEDS are wired differently on the BB2 then they are in the program. That is a level of HIGH turns them off and a level of LOW turns them on. It should look something like:

main counter var word ;must define variables BB2 con 1 ; default for Bot Board 2 #ifdef BB2 red con P12 ;red LED on P0 yelhigh con P14 ;yelhigh LED on P1 green con P13 ;green LED on P2 #else ; old atom bot board red con P4 ;red LED on P0 yelhigh con P6 ;yelhigh LED on P1 green con P5 ;green LED on P2 #endif high red ;turn all the LEDs off high yelhigh high green loop ;main program loop low red ;turn on red LED pause 10000 ;wait 10 seconds high red ;turn off red LED low green ;turn on green LED pause 10000 ;wait 10 seconds high green ;turn off green LED for counter=1 to 10 ;This loop flashes the low green ;green LED 10 times pause 300 high green pause 300 next low yelhigh ;turn on yelhigh LED pause 3000 ;wait 3 second high yelhigh ;turn off yelhigh LED goto loop ;start over again end

P.S - Sorry about my editing of low to high in yellow

Thanks, that did the trick. This is an interesting departure from my programming experience to date!
