Will it be very hard to modify code to generate crosshairs? I think about one vertical line and one horizontal, both ~1-2px thic, with ability to move lines with buttons and save position in memory.
Is it possible to make something like this using an ATTiny85 or similar AVR micro? If so, can anybody help me and port the code? For some reason I don't like PICs very much, and I already have an AVR programmer. Thanks.
I have been trying to adapt this project to be used as OSD for FPV flying. Have a couple of 18F4550, 18F4450 etc. lying with me. So i want to re-use those. Would prefer to code in mplab X + PICkit2. I am unable to compile the code successfully. I am a newbie to micro-controller coding. Figured there might be some issues with the architecture difference (thus diff SFRs) between the 12F and 18F. Could you please point me in the right direction?
hello, in my country (germany) "they" donnt let me see your video . Can you plese deactivate the music or post an other vid w/out music? thanks and.. good job !!
I still have one of these units I built a few years ago now (2009), it suffers from massive sync issues, I think it's because it can't detect the sync pulses correctly, I have a few 1881N chips, can you please advise on which pin of the 1881N goes to which pin on the 683 and what code changes are necessary to make it work?
I assume the sync jitter is just down to the PIC comparator and nothing else?
So when you write "should work also with most of PIC " what does that mean.. i would love to prototype with a device i have around.. will 16F84A-20 work (at 25mhz)? 16f877A

in addition, you can use a 20 MHz clock or lower, but text overlay will be shorter. you can increase text length (and reduce pixel size) on a PIC18 by using x4 PLL to get a 40 MH clock with a 10 MHz crystal
Hi, any PIC16, PIC18 or other MCU with a comparator and a timer should work with only a few adjustments you can use a PIC16F84A but you will have to add a video sync separator IC like LM1881 or equivalent. if you have video sync problems use it anyway, you can connect its composit sync output to a port on change interrupt pin instead of comparator interrupt.
This is awesome.. i was hoping to do some Cheap easy OSD for a tiny project of mine and im pretty sure you just saved me a lot of hazzle.
im mostly familiar with atmel and msp430s.. so when you say "should work also with most of PIC" can you clarify the requirements for the pic a bit.. besides the 25mhz clock ?
id love to prototype with some pics i have in the drawer.. would it work with 16F84As? if i can even clock it at 25Mhz? i mostly have "old" pics 18F4220 12c509 18f458
