 | | proposed new word for deleting pbforth
|
|
It would be handy if there was a word that deleted firmware. It is often inconvenient to get at the batteries. At Kekoa I see the opcode but no rom entry point. Trashing the header in memory and jumping to the reset vector might do it. I wonder if (...) (24 years ago, 16-May-00, to lugnet.robotics.rcx.pbforth, lugnet.robotics.rcx)

Firmware download is not working. I'm sorry but I never tried this with the first release. A second problem is that it gives no error message if the firmware download fails. I got suspicious because the download was too fast and the LCD was not (...) (24 years ago, 16-May-00, to lugnet.robotics.rcx.pbforth)

Ralph, I'm getting tired of losing characters going to the RCX on the serial port because forth is busy. It is making my work more complex than it needs to be.

Ralph, I suggest that you factor a proceedure out of the tcl uploadScript that sends a string to the RCX. This could then be used for additional menu or tcl commands that send Forth code to the RCX.
