Propeller Based Video Overlay (OSD) Module

sparks

Hi Bean,
do you still have the 79.00 kits available, or is it possible to get the OSD withOUT the DB-9 added(dont want the extra weight).

and I should have asked , have u or anyone else tested the OSD with the "oracle" diversity receiver front end(uses a missing sync detector) from dpcav.com

Sparks,
· At the moment I am out of stock on the HC-OSD (they have been selling well). I will be getting more in about 2 weeks.
· I'll check to see if I have any that do not have the thru-hole parts. But I don't know of any right off hand.
· You can purchase them at sparkfun, they have plenty in stock. http://www.sparkfun.com/commerce/product_info.php?products_id=8421

· I have not tried it with the "oracle" receiver, but the source code is available on the website so you should be able to make it work with any receiver. http://www.hittconsulting.com/products/hcosd/

Bean.

Hi bean,
never mind I am hacking my propeller proto board with the extended OSD code based on yours by perry
thanks to you both for the code and ideas..

I'm trying to modify this to use different pins. I have the PropRPM board, and it uses a different set of pins for video out.

It uses P12-p15 (different resistors on each pin I believe)... I'm using P12 since it appears to have a 1k resistor on it similar to P1 does in the schematic for the overlay.

So my question is, what do I need to modify to change this code to use P12 instead of P1?

VideoColorsOverlay LONG $00_00_02_00 ' Modify if not using pin1 for output
VideoColorsGen LONG $00_00_04_00 ' Modify if not usine pin2 for output

I found these two lines, but I'm unsure if this is the only thing I need to change... and I'm also unsure of what to change it to Are these the memory addresses for the pins? If so, is there a reference somewhere so I can lookup the address for P12?

Thank you!

Anything which references DIRA, INA, or OUTA (and the prereqs and results of those operations) will need to be changed to match the pin requirements.· Note: sometimes people attach devices to P0..n to avoid shifting data.· VCFG (if used) will also need to be changed.· VCFG[noparse][[/noparse]9..11] specifies the group of pins used ([noparse][[/noparse]0..7] or [noparse][[/noparse]8..15] or [noparse][[/noparse]16..23] etc), VCFG[noparse][[/noparse]0..7] is a bit mask of which pins are active and VCFG[noparse][[/noparse]29.30] determines whether composite video uses the low or high 4 pins.
