So fingers have 3 properties:
Pressure - user defined. Good for finding dodgy solder joints
Heat - source, or if unlucky, sink.
Capacitance - about 50pF.

Which of these is the most like ...

We use the Dorji units and reliably get 300m outdoor and 100m indoor with them. They would probably go further, but we don't need them to. ...

The SLA is a really good idea.

I think it is a really cheap price for the service offered. I am glad to pay it when it rolls around each year. Great value.

Even if I don't use the extra help in ...

Hi Toto,

My opinion without any evidence to back it up is that it is a hardware problem rather that software. Transients can really spoil your day.

I say this with a background of using RS485 fo ...

Thanks for the advice, Kimmi.

This works:

if req_tx_reply = 1 then
incr reply_tx_delay
if reply_tx_delay > 1 then

' Morning Kimmi, (at least it is here).

I did avail myself of the help over several cups of coffee, but that is what got me to here.

I guess my question is does the number (in this case 4, but t ...

Hi Folks,

I am flailing about in a serial handling routine, and am trying to get printbin to work.

So I read the RS485 serial string, and take action based on the match in a CASE statement. That ...

Hi Eddy,

a resistor is series with tx and rx lines will reduce the available current. Selecting the Brown Out Detection voltage to near rail voltage will mean when the voltage drops due to the remo ...

Have you tried putting a cap on the power rails directly at the sensor? Something like a 1uf tant will get rid of most induced noise while providing a little up-time for the current pulses.

Hi mmarlette,

The &B signifies to the compiler the data following is binary. A directive exists for hex as well, this being &H. So the following lines are equivalent:

Try an ISP frequency of 125kHz. If that works, you can always crank up the speed until it fails.

The increased programming time is negligible on these small parts. There is hardly enough time to th ...
