 | | Downloading Firmware to RCX
|
| Is there a description anywhere of the RCX firmware download protocol in plain English or in pseudocode? I am trying to write a QBasic program to do it. I have looked at firmdl.txt and dltrace.txt but my knowledge of C is not sufficient to work out (...) (26 years ago, 2-Jan-99, to lugnet.robotics)

| | using firmdl under win95
|
| Hi Folks, does anybody know how to use firmdl.c under Windows95 ? I compiled it using cygwin32-b19, and it allways hangs in the rcx_send function in the first read-statement, when trying to get the echo back from the RCX. Looks like read is (...) (26 years ago, 1-Dec-98, to lugnet.robotics)
