Re: MAX7456 OSD video overlay code
Hi all In the code the 'GetCharCodeFromTable()' routine was used. How would you use the existing character set of the MAX7456 in Swordfish? If I was to use custom characters, I would first have to make and load them to the memory of the MAX7456 chip (I am not asking how to do it, as there are tutori...

Two watchdod timers enabled?
I am building a device that is supposed to work on its own for a couple of a months in a row. I mean that I can not over see its operation. I am a bit worried that my program should run for such a long time without getting stuck somewhere. Now I know that watchdog timer (WDT) can be used to ensure t...

pic to pic communication
I need to send simple data from one pic to another. I read somewhere that "connect TX of the PIC1 to the RX of the PIC2, an you're set". How is the data sent and read? Do I use the USART.Write -command to send data and then from the other pic I test the PIR1.5 to read data? I need to configure baudr...

reading rf-remote controller signal
Lo! I have a simple rf-remote and a reciever for it. The remote has 22 functions, and I just need to make a PIC to react when a command is sent. I've used the Ir protocol analyzer http://ostan.cz/IR_protocol_analyzer/ to see what the remote controller is sending (in TTL-logic): http://users.tkk.fi/u...

The CCP module tip is just what I needed. Thanks. I'm trying to figure out how to write the code to use the capture mode in CCP. I looked the datasheet of my pic (PIC18f2420), and I also looked the "Using PWM with Swordfish" from the SwordfishWiki pages, but I have to admit that they didn't really h...

reading PWM with pic
How to read pulse width modulation (PWM) signal that is fed to a pic?
Should I make a timer which starts with a rising signal and stops with falling signal?
Or should I try to transfer the PWM to analog signal (voltage), which I would be able to read?
Any advise?
thanks already in advance..

Lo! I have a similar situation as AndyO. And I'm a noob as well. I'm building a radio controlled window shades, and I'd like the result not only work, but to look good as well. For this reason I'd like to use a ready remote controll, like this one: http://www.beckermotors.co.uk/ec545-p-39.html How e...

How to produce sound
I'd like to add a tune to my project. For some reason I can't find how to do this. And I don't want a really complex system like in the SDMMCWavPlayer-example. I'm trying to find a simple way to create a tune. I assume it is possible to write a frequency and duration for every note? What would the c...
