pic pwm decoding
Yes , i have access to the reciever.
The transmitters have two buttons . the first arms the car alarm , the second activates a panic alarm when the alarm is disabled . The alarm has a LED "ARMED" output so I wired a SSR to that and I use it to remote turn on some lights in my...
remote control+pic+pwm
Hi bunalmis, :lol:
The transmitters that I have use a PIC and definatley you PWM as an out put .
They transmit a 25bit signal (3 * 8bit + a "0" at the start for preamble)
A "0" is 300uS high then 600uS low , a "1" is 600uS high then 300uS low.
I was going to sample...
Hi ,
Does anybody have any code written in C to decode the PWM output of a RF remote control (from a car alarm) . Doesn't have to be code hopping just read the code so that I can display it .
Thanks in advance

Mr Cool,
Your chip is a definatly a 4MHz version , the -04 at the end tells you that . If you had a 20MHz version it would be -20 etc.
What type of breadboard are you using ?
Is it the solder type (eg vero board or strip board ) or is it the plastic breadboard type where you plug components...
Mr Cool ,
Forget about the software its sounds like a hardware issue. I had exactley the same problem when I first started using PICs ! The Crystal needs 2 capacitors tied to ground to work correctly. I normally use 30pF but 27pF will do .
The problem I had was due to me using strip board (or...

I have managed to get a handfull of Altera EPM7064 devices . Does anybody have any nice projects I can use them for ??
Thanks

BGA's are placed using high precision pick and place equipment that typically uses a video system to align the PCB . The PCB will have solder paste stenciled onto the board and this holds the device in place as it goes through a reflow oven . The ovens...
Does anybody know where I can buy a cheap PICDEM.net board in the UK ?
The £250+ price from Microchip is a little bit high for me !
Thanks

Hi Guys,
Anybody got a schematic for a 2.4GHz video transmitter / reciever. I need to transmit over a range of about a mile !!
Thx's for any info
