I’m having all sorts of trouble trying to get these things up and running. I’m trying to take serial out of a PICAXE 28X1 and send it to a remote serial graphis LCD. At the moment I can’t even see the data on a CRO at the RX end.
Any help would be greatly appreciated!!!
I haven’t used these yet but I’m thinking about it. Obvious stuff from the docs (forgive if you’ve checked all these):
Is sleep grounded?
Is reset high?
Are you using the correct serial port? (Looks like you should use com1 for TTL as directly out of a PIC)
Do you have Tx and Rx in the right direction? (output of PIC to input of radio?)
Is the signal ground connected to the power ground?
I hope you can get this running, it would be good for a similar project I’m doing. Let me know how it goes!
