 | | Patched firmware to improve rotation sensor, was Re: Robolab, byte codes and assembler

| Hello Dick, Looks great, but it doesn't seem to work well here: - counts up 2 by 2, but counts down correctly one by one - loses count, especially when counting up. My tests were done with a brand new, unmodified rotation sensor. I mounted a wheel (...) (21 years ago, 29-Nov-03, to lugnet.robotics, lugnet.robotics.rcx.robolab)

| (...) I'm having trouble downloading the patched firmware. Robolab doesn't have a .lgo file anywhere in the program directory structure, so I don't have a filename to replace with the patched file. Downloading in Robolab seems to work, but I see no (...) (21 years ago, 29-Nov-03, to lugnet.robotics, lugnet.robotics.rcx.robolab)

| Hello Don, (...) firm0309.lgo is firmware from RIS 1.5, while firm0328.lgo comes from RIS 2.0. Maybe RIS 1.5 can't download 2.0 firmware, never tried that... (...) I suggest you download BricxCC from (URL) and use its download utility (located in (...) (21 years ago, 29-Nov-03, to lugnet.robotics, lugnet.robotics.rcx.robolab)

| (...) I think RoboLab uses its own firmware, so patching FIRM0328.LGO won't help you unless you use the RIS programming environment. (Or NQC, but that apparently isn't allowed by FIRST?) (...) I've used FIRM0328.LGO with older (version 1.0) RCXes (...) (21 years ago, 29-Nov-03, to lugnet.robotics, lugnet.robotics.rcx.robolab)
