Why not post your schematic and some of your code so that we can be more help. Just telling us that you have tried lots of different things with no success doesn't give anyone a starting point to...

Let's do the math....
GalUse = 1600 - 1475 'which equals 125, this is fine

MPG = 3280/125 'which equals 26.24 and the .24 is lost because PBP doesn't handle floating point. Therefore in your...

Several years ago I attended a Microchip seminar where they had a number of displays showing the capabilities of their microcontrollers. They had two demo boards in different rooms demonstrating...

I found the article. Parallax has an archive of nuts and volts columns that pertain to basic stamps.

I did purchase a version 3 one wire weather station from AAG this past year, that's what is connected to my weather server. I still have the original Dallas weather station with the 'ID Tags' for...

I have spent much of my free time in the last year building a weather server for my AAG weather station, humidity sensor and TAI-8570 baro pressure sensor. I decided to do this after reading an...

Try:

led var byte

instead of:

led var porta.0

You are defining 'led' to a port pin and then trying to poke it into another port pin.

I fully understand how overwhelming they can be. I've been trying to get my head wrapped around the DS2406 datasheet and trying to understand how the one wire commands can be used to communicate...

I don't believe that using a 20mhz clock would even come close to working. If you look at the timing diagrams the clk has to transition low to high for each bit that you are reading in. The...

I was a bit too quick to reply to your post. Shiftout will write to a device and Shiftin is used to read from a device. You will want to concentrate on Shiftout to communicate with the DS1802.

Take a look at the timing diagram on page 9 of the datasheet (Figure 6a). The clk line needs to be connected to a port pin and it makes a transition signaling that a 'new bit' is ready to be latched...

BigWumpus, it's not that I don't want to realize it. It's that I didn't realize it. I went back again to the link that Melanie sent and looked line by line at the code there and now I understand...

Thank you Melanie. I know this has been beaten to death. All the info I have uncovered while searching 'I2Cslave' and 'Slave' etc... Just explains implementing it using the built in SSP. The...

Does anyone have any ideas on how to implement an I2C Slave using an 84A? I have read the PBP thread and examples for master/slave and the slave is accomplished using the hardware I2C port. Th 84A...

Hello everyone -
I have built (18f252, AAG 1-wire weather station, DS1910 humidity sensor,etc) a front end for my weather station and have now purchased an AAG TAI-8570 pressure sensor. I have...
