MPXA4115A picbasic code

[bitmaniac]

(SO....I have to see both codes side by side so I can learn for my mistakes )

You 've done excellent coding ...I'll give it a try although I had problems with averaging routines -keep sending '0' as result!

I agree with Walter.
All this "Software Timed" stuff just doesn't work well together.

Everything, should be Interrupt driven.

Capture (CCP) the received pulses.
Use A/D interrupt to OverSample the Altitude. (oversampling does not have to be "Blocking")
Timer interrupt to drive the servo.

No PULSIN's, no PULSOUT's, no SHIFTIN/OUT.

These PIC chips are extremely fast. (As long as the program isn't sitting in a loop somewhere waisting 90% of it's time.)
And with the Hardware doing most of the work, they "Scream".

Even if you don't use Interrupts ... Use the hardware.

Hi, Alex ...

just two little "bugs" of mine ...

'---------------------------------------------------------------------------
pause 3000

for x=1 to 4
	high led
	pause 200
	low led
	pause 100
next x

... I only forgot to clear the comments for shortening delays when using MPSIM ...

Here is the good sequence ...

AND

Average:' -=-=-=-=-=-=  Average 16 X Analog values -=-=-=-=-=-=-=-=-=-=

Value = 0

  For x = 0 to 15			' 16 Samples MAXI !!!
  
  shiftin ADC_DATA,ADC_SCLK,msbpost,[advalue\12]	'337 µs
  
  value = value + advalue

Forgot resetting "value" ... Boooo.


But ... you of course had noticed it !

PS for Darrel ...

Everything, should be Interrupt driven.

You really sure ??? ... not me, here for R/C Gadgets ...
