Re: module for the HMC5883L compass

After some searching for a sensor that is available I found a breakout board at sparkfun that has a simple code that dosen't use any adrunio library. now I need to convert to Swordfish to load into a pic. then instead of an lcd (will use opti-coupler) in final project). #include <SparkFun_MAG3110.h>...

found what may be a better solution https://www.memsic.com/userfiles/files/Datasheets/Accelerometer-Datasheets/MXD2020E_FRevH.pdf has PWM as well as A/D output Now to figure out how to implement. Microchip has a paper on it AN996 http://ww1.microchip.com/downloads/en/AppNotes/00996a.pdf now the fun ...

module for the HMC5883L compass

Want to experiment using an electronic compass and all I find are Adriuno library stuff and one using an 18F4550 but in C.
So I guess I need to convert the C source code into Swordfish (familiar territory) but???
I figure I would inquire if anyone has dealt with an electronic compass using Swordfish?

Re: 18f24K40

After reviewing my plan and end product I am going back to the 18f2221
In this application there is no real advantage of using a K series pic.
Thanks for the input as I WILL be utilizing a K series pic for my Christmas project that is on the back burner

Re: 18f24K40

got the "simple" code done involving the HLVD section but got to wondering if the HLVDCON value be changed using a sub route. Is what I am contemplating is having the LOW voltage detect LED0 blink at a faster rate as the battery goes lower. In this code (haven't calibrated the pickit2 voltage but th...

Re: 18f24K40

Looks like a slight change in part number. Instead of the 18f24K22 going with the 18f24K20. Cheaper at mouser for 10 units plus I happen to have several of these puppies on hand.
Onward to locating white leds and writing code to include the HLVD

Re: 18f24K40

Thanks, I thought I didn't have the INCLUDE modules in the right folder but after looking at your example I see my mistake. Now to order the 10 chips SMD and one in a dip for testing my code for proper functioning HLVD etc. was slightly worried why it wouldn't compile. Need to make some changes to t...

Re: 18f24K40

Thanks guys, the link that bitfogav posted a link to shed some light on what and why my project using a K pic seems slow. Will go back and review what I have as well as the setalldigital.bas. Yes the setalldigital was from Diy. but looking over the code it has the 24K22 // 18FxxK20 family (no LF ver...

Re: 18f24K40

It pays to shop
the 18f24K22 at Mouser = $2.50 Digi-key = $2.14
now just need to order and write code for it. Maybe the SetDigitalIO.bas module will work better??

Re: 18f24K40

Thanks Jerry I have several 18f24K22 that work but seem slow. Why I have no idea. Checked the osscilator setting etc. he nly way I can get it running half way decent is to use INTOSC8.bas. The InternalOscillator.bas won't work, or at least I don't see the device listed in the module. Will proceed wi...

18f24K40

this is a new chip?? but can SF / pickit2 even deal with it. I see no modules etc such as setalldigital. Am I digging a hole and no way out. This pic for cost is only $1.50 from Mouser. Only reason I am considering using this pic. Might run and use the 18f2221 but?? I have no need for lots of bells ...
