Title: Problem with wiring versions 24-26 Post by Titus on 03/12/10 at 15:19:59
Dear Barragan,
I started to work on my robot lately, and I had some troubles with the software versions 24-26. If you want to upload at 0023, you press upload, save the file, push the reset button and wait, within seconds the program starts uploading. Now compare this to 0024-0026: Press upload, save file, reset, wait, programmer not responding: FAIL It does work when you do this: press upload, save file, reset, wait for the old program to run, reset again, and the new program starts to upload.

hi Titus, the compile time for versions 24 and above seem a bit longer due to optimizations and the new library scheme, if your board is not auto-reset try the manual reset when uploading a bit later than usual, just to make sure the board will be ready to receive the new program.

I have a manual reset board, so I explored the reset/comm problem on versions 0007, 0023, 0025, 0026
Conclusions: a) 0026: click upload, then click RESET twice, 1 second apart, finds the atmega 99% of time. b) 0026/0023: new compile is factor of ten slower (8.00/0.75) c) I need the micros() call, thus i must use 0024 or later. |
