programming the Hilltopper Arduino chip
|
Charles W. Powell
Is the spot on the board for a 6 pin header, behind the Si5351 board, for programming the Arduino chip? If so, how do I interface this with my Arduino board? It would be nice to be able to program the chip without prying it in and out. At this point, there are so many changes I'd like to try that I could be pulling that chip out 10 times in a day.

Chas- Yes- that's it. From left to right Hillttopper Arduino J5 pin 1 ............. ground J5 pin 2 .............. (no connection) J5 pin 3 .............. 5V J5 pin 4 .............. D0 J5 pin 5 ...............D1 J5 pin 6 ...............Reset You need 5 male/female jumpers between the Hilltopper and the Arduino. Each socket position on the Arduino is labeled as shown above. Important: Remove the Arduino's ATmega328P (28-pin DIP) and set it aside. - Dave

Thanks Dave. As it turns out, I have some extra chips for the Arduino but I think I misplaced the original. After all, space is, after all, the final frontier. Especially the space between my ears.

I assume the radio should *not* be on for this operation? 72, Chas - NK8O

Chas- Radio Off during programming? It doesn't matter- I've done it both ways. 'Off' requires unplugging the 12V power cable. Easy to forget to plug it back in and wind up puzzled. - Dave

Programming changes to the Hilltopper display. Again, nothing very creative and mostly cosmetic, but I get by with a little help from my friends (Bernie, K6NAZ). Display now toggles RIT between off and on. Now I’m going to work on making all three radios, 40-30-20, perform uniformly.

Chas- What does the 's' stand for? I'd set mine up (on an old project) to display '+' or '-'. RIT ON with no offset was a special case- I blanked the symbol. - Dave

The ’s’ is the tuning step. That was in the original code from Lloyd, WA4EFS. I have the radio set for 500 Hz, 100 Hz, or 10 Hz tuning steps. The RIT of course follows the the same ∆f as the main dial. I think it’s possible to display the actual deviation of the RIT but that will require a little more research on my part - or arm twisting for help writing the code.

As it turns out Dave, if you want to add Hz to the end of the line, the characters don’t all fit if you leave the ’s’. I just compiled the code for the HT-30 and there are too many characters for the line length. Lloyd didn’t have the Hz designation. One could also leave out the trailing ‘0’ in the display, since it doesn’t change. All window dressing nonetheless.

‘s’ for ‘step’ – The displays look very nice. Have you described the RIT implementation somewhere?

Oops. Guess I should read the manual—must have skipped that page. J

I have to drive this evening but in the next day or so I will post the code with my modifications. I just finished the 20 meter code (had to install headers on the HT-20 board) and it seems to work as expected.

Keep thinking about Kd1JV's open source code here: http://kd1jv.qrpradio.com/XMEGA/XMEGA.htm. Wondering if the code could be adapted to run a Hilltopper. I know there are some additional push buttons needed for all of the functions, but that is a fairly low hurdle. The notes say just load something called "FLIP" from Atmel site onto laptop and eventually load provided code through USB to controller. The provided code is Assembly language.
I built an ATS-3B years ago ( kick myself for selling it ) and the functionality with five momentary push buttons was breathtaking. I believe it was running this code. Besides the audible frequency it had a single digit display that displayed the frequency. And a multiple memory iambic keyer. Guess as is typical of some hams, am always thinking about modifying stuff. Curt KB5JO
