#### Re: Newbie Manchester Coding question

Looks straight forward, esp if you use a chip with gate control and can set a timer to count in 1uS increments

what did you have in mind ?

#### Re: Watchdog timer not working as expected

From the PB3 manual

2.15 Case Sensitivity
PBP is not case sensitive, but Assembly Language is. This means that there are
situations where case matters

#### Re: Newbie Manchester Coding question

Apologies, I was beginning to think nobody was responding so it's been couple of days since I've checked.

They're old temperature sensors I picked up cheap and I was hoping to utilise for a...

#### Complex math on 16F series?

d = 1 / ((x1 - x2) * (x1 - x3) * (x2 - x3));
a = d * (x1 * (y3 - y2) + x2 * (y1 - y3) + x3 * (y2 - y1));
b = d * (x1 * x1 * (y2 - y3) + x2 * x2 * (y3 - y1) + x3 * x3 * (y1 - y2));
c = d * (x1 * x2...

#### Re: Si4702 FM Radio chip

My code in here is probably more sensible for PBP. In code examples is dirty to get most out of 16F628a.

Up to you, but that DT code link above is an otherwise lost original I think (which I...
