Other dubious news - I've apparently succeeded in writing something to the Sanguinololu - the menu no longer shows on the display. This will be educational, if not fun...

Good news! My cousin helped me out and we got the firmware installed! Now I just need to figure out... everything else. :-)

For anyone else in my situation, the baud rate was 57600 and programmer should be arduino, not stk500 for the sanguinololu. It may have had the bootloader after all, but we'll never know now. :-)

Fair enough. At least now the next person who goes looking will have this as a reference. I guess this begs the question of how hard it would be to edit the bootloader to change the baud rate?...
View ArticleRe: Teacup on Sanginololu under Win 7
Uhm, there are no "global constants" ... Baud rate is hardcoded in the bootloader. The ones coming with Gen7 Arduino IDE Support are hardcoded to 115200 baud. It's also a number relative to the CPU...

Sorry, not really a programmer, clearly. I meant a defined value like a #define. I realize it's hard coded in the bootloader, but is the bootloader itself closed source? If not, could it be possible...
View ArticleRe: Teacup on Sanginololu under Win 7
If the bootloader is closed source, where would you put this #define? Write it with a pencil on the back of the chip? :-) Luckily it's Open Source: [github.com] There are other Open Source bootloaders...
View ArticleRe: Teacup on Sanginololu under Win 7
Yes, yes, I know what open source means. :-) If I was playing with the bootloader much, I might actually write the baud rate on the chip with a pencil. ;-) Or if I had multiple chips/controller...

Glad that fancy piece of paper left me with some deductive skills and a little feeling for error messages. :) Two out of four likely candidates do, in fact, have a parallel port. I can load whatever...

It occurs to me that the ISP may be doubling for the display header. Pretty sure one of the pin clusters it's plugged into is a 2x3. I'll check it out when I get home tonight or tomorrow and report...

Can do. Hopefully I can get to it tomorrow after work, but no promises. 12 hour shifts eat your work days. :)

Try them. Once there's a bootloader on the chip three's no need to ever look back.

Update:the Pro Micro seems to have taken the Arduino ISP code, but I need a cable now, and would like something a bit more elegant than bits of CAT5 stuck to a few strips of 1x header strip. I'll try...

Attempting to use a Pro Micro to burn the bootloader to the Sanguinololu gives me the following: Arduino: 1.6.4 (Windows 7), Board: "Sanguino, ATmega1284 or ATmega1284P (16 MHz)" C:\Program Files...
