Best way to synchronize PINK with an LED display? Pg 2 of PINK manual unclear..

latigerlilly

Hi guys,

The following program in this post doesn't work. It will not light up the LED display at all. The funny thing is, the program in the second post in this thread does light up the LED display. The parts of the program that lights up the LED display are identical in the two programs.

Basically, I want to use an online form to update variable 01 in the PINK. Then, the Basic Stamp 2p40 on the PDB will check what the value of this variable is. If it is "god", then the LED display on the PDB will show "god". If it is "odd" then the LED display on the PDB will show "odd". Otherwise, the LED display will show "dog". The funny thing is, it will not display anything, not even "dog". MY QUESTION, "What am I doing wrong that will not allow the LED display to work in this post but allows the LED display to work in the second post in this thread?

The problem is not with the online form. The online form will update the varialbe fine. It will also display the variable with no problems. The third post in this thread contains the online form.

I have connected the PINK to my Stamp 2P40 on the PDB according to the illustration on page 2 of the PINK manual: www.parallax.com/dl/docs/prod/comm/30013-PINK-v1.02.pdf The only thing I can think of is, the PINK manual says "serial out" on the PINK is connected to P12 on the BASIC STAMP. I am interpreting this as "out" on the PINK is connected to "in" on the BASIC stamp. So, P12 is "serial in" on the Basic Stamp. In other words, you will use "SERIN 12,1021,[noparse][[/noparse]STR NBVAR\3]" to receive data from PINK to the Basic Stamp. Am I correct or wrong? Here is a schematic:


Thanks,
Lilly.

Hello,

The PINK documentation will be revised to be more clear. The current documentation makes reference only to the physical pin on the module when it should refer to an I/O pin number. Physical pin 12 as shown in the diagram is actually P7. So P7 is the input on the BS2 in that example from the serial out of the PINK. The line connected to pin 13 is actually P8. These will be changed in a future revision of the documentation and both pins will be on the same I/O group. Hopefully this will help you out. Take care.

Please tell me what I did wrong. The LED display in the first post in this thread still will not turn on. I double checked. All the connections were tight and the BS2P40 is flush mounted tightly on the PDB. Not even the default "dog" would turn on. Thank you.
