Re: following error question

Hi Dale

To further Ray's comment, the fix is very simple. In emc/src/emcmot/dro.c

int LS7266Init() {
  int t;
  for (t = 0; t < 4; t++) {
    /* set present flag to true, clear it later if not there */
    Present[t] = 1;
    /* if even, initialize chip half */
    if (! t % 2) {

Change the last line to :-

    if (! (t % 2)) {

Just the addition of two parentheses changes the way the test is evaluated. 
The original method is incorrect so the initalization is only performed once 
when t=0. In the latter case the code is executed when t=0 and t=2.

BTW A few bugs have been fixed elsewhere in the code since BDI-2.10, so it 
may pay to update to the current CVS sources.

Regards, Paul.
