error in memory manager

 

I am trying to learn how to manage the uBITX programming while waiting on mine to arrive.

I have a nano and LCD hooked up and can load in the hex file and see the display.

When I call up the memory manager I can see the display reboot.? When I try to read the nano I get an error.


Shows the time, then Error Receive Length= 1/1027


I have tried several versions of both the memory manager and the programming.

Last try was MM 1.04 and program 1.073.

Since you have a spare NANO and are learning programming, it might be interesting
to make that Arduino into one or more of several pieces of test equipment that will
support your uBITX when it does arrive.? With its ADC (Analog) inputs the NANO could
be a digital voltmeter with manual or automatic ranging.? Using any of several thermal
sensors to make a contact or IR based thermometer for BITX RF PA stages.? And of course
a signal generator with an Si5351a.? Or frequency meter with a N/10 prescaler (or N/100
for up to VHF measurements).?

This software then could eventually be folded into a built-in-test-equipment suite for
BITX systems.

Hello Ralph,

I would check the communication parameters:

1. Have you got the right USB port (the same as for uploading the HEX file). I suspect you have that right as it reads one byte, but please double check.

2. The parameters are 38400, None (for parity), 8 (bits data), One (stop bit). This is different to the programming settings as it communicates with the CAT section of the uploaded program.

Thanks very much John,

That was the problem.? I needed to set the baud rate to 38,400.? The default value that comes up on the MM screen.? ?

I must have misread the instructions as there is a spot on the 'user manual' about setting the baud rate to 9600.??

If I have any other problems with loading in the programs I will check the baud rate and try several.??

I was able to load in the hex code using another program just fine.? When I tried the memory manager i had the port ok and the parity and data bits, When I tried to connect, the display of the Nano would blink but got an error code from the MM.??

My uBitx came into day.? It was ordered on April 9 and had DHL shipping.? Now all I have to do is put it in a box and see if it works and if so, try the other programs as they look to be very nice.

Glad you got it to work Ralph.

Have fun with the uBitx. I think I went a bit overboard with the add-ons on mine, but it was too much fun to stop...hihi

When I try to use uBITX Manager Ver 0.11 with COM port set to 38400-N-8-1, the Raduino crashes and shows "db>4000000" which I assume mean that it has dropped into its micro debugger.? :-(? This is with factory default firmware which displays "uBITX v4.3" and "USB A:14.252.550" at startup.? I was hoping to use uBITX Manager to back up the current settings before trying CEC firmware.? Any ideas?

UBitx Manager is intended for use with CEC firmware, not the factory default firmware.? It cannot connect to the default factory firmware, as the manufacturer does not include any handlers to respond to UBITx Manager!

Don't worry though, the CEC firmware won't change the settings you have entered in calibrating your txcvr.? You can do a back up the first time you connect to CEC firmware.

Thanks, Mike!? That really clears it up.
