Still stumped with the maths to try get the numbers is giving me into a usable number, anyone that can advise?

ALso, does anyone have any examples of where / how to capture the TMR overflow?

One correction to the code, the hall sensor is on RB0 not in PortB.0.

RB0 is pulled high and the hall sensor pulls it low when the magnet passes (would like to still change this around but assume...

Hi All,

Well, the count didn’t work as expected, seems the count function will only work for >100-150 rpm measurements, :-(. Even an event measured in 1 second, multiplied out the LCD reads it as...

Hi All,

Been a slow coding month, although I have been thinking and reading on how to do it, think i have settled on a disk option using a Phototransistor and counting the triggers every 1.5s...

Question, would powering the pic from a LM7805 (5v reg - giving 5.01v on the DMM) make a difference? all the others I power from the Rx, this one i've decided to use an external battery regulated...

Damm, been busy this afternoon with the Pickit 2 and seems i still get the same issues, at least now i'm not killing Pics at a serious rate, even managed to recover some the winpic wouldnt read...

Just bought a Pickit 2, reckon my dodgy homebrew programmer might be a part of the issue, think i've been through 10 PICs in the last 2 hours keeps bombing the OSCAL value and toasting them, :-(

Well, so i plugged the 12f onto the breadboard that has a 18f connected to a LCD and programed the 18F to show me what pulsin was giving me, the pulsin value ranges between around 120 and 180 which...

I actually have a Max232N board hanging around that i made up some time back and never used, will have a look at the DS again and see how to connect it again, :-) see if it can give me abything...

Thought about that too, tried it on a 2.4ghz set (which should be a more solid signal) and yet it still does it, also I would expect it to remain in the last state when the Rx is off yet they still...

Hi All,

Below is my code for turning on and off the landing lights of an RC model, however, I find the lights turning on and off randomly.... ??? ... confused...

I'm using a 12F675, the pin...

Hi Bob,

I totally agree, I have been playing with the manual AD routines and find it much more stable than the ADCIN function ,:-), the only question is which 18F to use, currently i have a...

Were you interfacing the Memsic to a pic or into something like an Aurdino / Propeller / Stamp? I've used the 3-axis versions quite a bit in my Tri-copter build, but was hoping to interface to a PIC,...

Going to go dig in my old PC drawers tonight and see what i can dig up, was planning on a DC brushless fan motor but could not get it to give me anything usefull, perhaps a DVD/CDrom motor may also...

mmmm, this is all sounding way past my current / very limited PicBasicskills, sounded quite "easy" at first but seems to be very deceptive.

Had another thought that may make this a bit easier to...

Dave, that would work, although I would expect it to need quite a stiff wind to get over the mass of the bells? what did you use for a pickup? are there any more details of your project posted...

Agreed, the weather proofing of a homemade "stick and cup" versionis an issue, however I have managed to source a commercial replacement set thatis UV treated etc., so that should solve the longevity...

Hi Dave,

:-), well, the 20hz refresh was a number i was thinking of, realistically i dont think i would need such a fine resolution. I know it has been done with a simple bicycle speedo which...

Yup, should use the same principle, although in a car with the vibration i would suspect you would be better off using a Hal effect sensor, but then you would also need an opto amp of some sorts?

Hi Guys and ladies,

Finally managed to get back into my pic development, :-)

On one hand i want to continue my pressure sensor project, on the other I'dlike to start a "quick" DIY anemometer...

Error, :-( looked at it last night and cant use the track under the PIC, will have to try the "Slam-read" option which seems viable or use the other PIN and leave that side empty until I have some...

Hi Charles,

I will give your option a go tonight, :-), should work for what I need it to do. Was thinking to monitor the pin for a few cycles and if it floated to read it as open and if it was...

Sorry, basically, all the jumper is doing is on boot it the Pic check if it is "on" and then goes into a setup mode to sense the Transmitter stick location.

What I have done this evening is...

Damm, so what you are sayins is that im out of luck either way? Spose the only way to do it is to bridge the jumper permanenetly and hardcode the ranges for these boards?

Sorry, attached is the picture. the black circle is the area showing the 2 sets of jumpers connected to GPIO 4 and 5, the red circle is the 0402 SMD 1K resistor. I am using a 12f675/9 as the PIC and...
