radio cotrolled pulse width to voltage converter

I am using a PSOC cy8c29466

CY8C29466-24PXI Datasheet pdf - PSoC™ Mixed Signal Array - Cypress

If you are using a normal RC system and not a spread spectrum system then the signals do not overlap. A pic can easily read 4 signals to an accuracy of 1uS (or better) and it will still have 98% of it's processing power available. The only interrupt required is the PortB change (IOC) and so all other interrupts are still available for the other devices.

I guess I have to use 4 inputs for the 4 PWM signals. And atleast 1 interrupt (depending on if I use counter or timer) for each input. These 4 interrupts trigger the same function and then I have to in some way figure out which input that called this interrupt. I could check which one that just went low with a bit of programming. This could might work, but I guess I also wanted to try it the analog way and I seemed to find it simpler.

this is the calculation I have no clue actually how it will work.

t=R*C
20ms * 100 = 2 seconds
2s / 1000ohm = 0,002F = 2mF = 2000uF
2s / 2000ohm = 1000uF
2s / 1mega ohm = 0,000002F = 2uF

hi Simon,
I would recheck your calculations....

Hello all
I want to thanks you for your help. I allways get great help in here. What I learned during this, was that there is almost never a reason to convert some digital to analog and the convert back again I fixed the problem with reading the digital pulses. I didnt kenw how to do that, (since im new) and wanted to do it the analog way. That was stupid, and now I learned to read digital signals which is easy, fast and nice
Hope it also helps other newbs out there!
