There seems to be a lot of people wanting to send fast pulses to devices using the `mite but there are obvious limitations to the capability to do this in an interpretive basic.

Now We have a video signal that is generated to drive VGA displays (using DMA??)... if MM/DMBasic was able to change `video' settings (to obvious out of range for display) to be able to be `infinitly' `adjustable' could we then create rapid pulses (when required) by using the Video output of the `mite this could be created by setting or clearing the required `pixels' to create the said pulse...

I am not a programmer, in fact I would say I am not a programmers @$$hole but some would disagree with me and say yes I am.. So I do not know how feasible this would be or not, just a glimmer of an idea and maybe someone smarter than me can see an oportunity here...

Maybe it should be setup as an `on call' rapid bit stream that can be called when required..

Someting like

VID_DISABLE ' stop the Video connector being used for VGA
Pulse_out xxx,yyy ' not sure of best format but setup a stream of pulses to be sent using this mode


Of course Video out would be compromised by doing this but we would still have USB console mode.

Am I crazy, well we all know I am but is it a possibility without too much alteration to the `mite firmware.
