RF Splitter/Combiner
Hi Charlie,
ReplyDeletelooking at your code and i have just a couple of comments ...
1. Why are you using a software serial port on pins 31 & 32, These two pins are actually for a hardware serial port on the teensy.
2.if you change all your code to read serial4 and NOT myserial the code will still work and run faster as its using a hardware UART.
3. why do you think you need a delay in the code to sort out possible errors
best regards
Simon M6FJW
Hi Simon. Thanks for that. I think that was an error, so I'll revisit that once the receiver hardware is complete. As for the delay, that's currently commented out. I did find at higher baud rates that WSJT-X they errors. I know the Teensy was sending the correct indo. It's currently working fine at 9600. Strange.

Charlie ZL2CTM
Hi Charlie,
DeleteFrom what you describe it could be a simple timing issue due to the large number of serial print statements that only send a single character. The faster the baud rate the less time you have to process and send data.
serial print strings rather than singular characters, It's more efficient.
The serial printing process goes similar to this ...
1.initialize the stream ready to send to the serial port.
2. send a stream of data (in your case a single letter).
3. close the stream.
Sending a string is more efficient as it sends a stream of data and spends a lot less time initializing and more time on sending actual data.
best regards
Simon M6FJW
Thanks Simon. I will look into that. I guess there will be some more effort (code) to build the char string, but probably worth it. Thanks again.
DeleteCharlie
Hi Charlie,
DeleteYou might think it's a lot more work, but it's actually less work. There are commands available that do most of the work that you need. I have some example code if you wish to see it let me know.
The code I have only uses 6 or 7 lines and deals with getting the command, data and semi colon out the serial buffer in to the strings.
The thing to remember is that CAT control just sends strings back and forth, It's the individual systems that convert to integers, Boolean values or characters for that system ( no need to think what number base, or bit depth the number system uses).
research the Serial commands all aspects of it are useful. There are commands that will fetch multiple bytes from the serial buffer in to a string or char array. These simplify the code. Add in the string commands that are available and you can quickly build a response to send in a single serial print line.
I hope this helps.
Best regards
Simon M6FJW
I will take a look at this Simon. I thought I was loading the received command into a char array. If i could, i will take a quick look at what you did and I'll go dform there. My address is my call at gmail. Thanks again for the steer. Charlie
DeleteHi Charlie,
Deletei have sent you an email with the sample code. yes you did use a character array, but you only used it a single character at a time in your serial print commands which could lead to serial timing issues.
best regards
Simon M6FJW
Hi charlie...can you tell how to get file teensy.SSD1306.h...or can you share the file...thanks
ReplyDeleteOnce you add in Arduino support for the teensy you should have it. If I recall, it comes up under Teensy within the Arduino IDE.
