TK, Thanks. This was for a debug operation I needed to perform, I figured a delay would cause a buffer overrun. Thanks you! Jerry

What is the syntax for MIOS_Delay(); from within sdcc? Every iteration I try fails. Thanks, Jerry

Wise, I am pleased to see a possibility. 100 meg ethernet works without issue for 300 ft. I am sure there is a way to have 2 meg 100% perfect over 100 ft. Looking at the DOUT data lines with a scope, it doesn't appear to be a whole lot different than RS232, just faster and using less robust master hardware (the 452). My DOUT module failures on long runs are most related to the 5+ volt line and voltage drop on long runs due to the current draw required by powering 32 opto-isolators for the triac boards, so I have changed to a ditributed power arrangment placing a7805 and filter caps on each DOUT card and running +12 on the power line, this has improved stabilityt. I will look into the line drivers, probably buy a few and build to see what it ends up running like. Thanks again! Jerry

I have succeeeded in building the core and 2 DOUT modules from scratch on proto boards. I have the capability of using MIDI "music" to controll 110 VAC light, sequencing by playing the keyboard into Cakewalk. In testing I have been able to get the DOUT modules to run on a maximum of 45 foot of cat5 wire. For my application (Christmas Lights), 45' would be OK however, I would like a total cable length of 100', some of this length is between DOUT modules some between Core and the first DOUT module. Is some way of extending this distance with an active line driver or some other design? Thanks!

I got SDCC...... Windows :) Thanks a million! Jerry

Thorsten, Thank you for the prompt response. Unfortunetly, I have yet to buy a C complier for the PIC processor and I can not get SDCC to compile anything, probably my error. I will make a run at this in assembly. Regards

Hello, a mios/midibox newby here.... I need (or at least want) the ability for my midio128 to be able to turn on one full DOUT bank(8 pins) on a single note on command, while yet another set of 8 note values control the same 8 pins individually. For example; 90 29 controls 1-2-3-4-5-6-7-8 all at once 90 30 controls 1 90 31 controls 2 .... 90 37 controls 7 Any suggestions for a solution? Regards, Jerry
