Software for Zachtek "WSPR-TX Version 1"
|
|
The Version of this software is stored in the constant "softwareversion" and is displayed on the Serialport att startup
|
|
For Arduino Pro Mini ATMega 328 8MHz
|
|
|
|
Hardware connections:
|
|
--------------------------
|
|
pin 2 and 3 is Sofware serial port to GPS module
|
|
pin 4 is Yellow Status LED. Used as StatusIndicator to display what state the software is currently in.
|
|
pin 8 is Red TX LED next to RF out SMA connecotr. Used as StatusIndicator to display when transmission occurs.
|
|
For Arduino Pro Mini 328 8MHz
|
|
|
|
Version History:
|
|
-------------------------------------
|
|
0.51 First Beta for Serial API
|
|
0.51 Expanded the Serial API and changed all information messages to {MIN} messages
|
|
0.52 [DGF] API updates will change SignalGen output freq if running.
