I think that the measurement should be about 10000 (microseconds) with the setup details provided, and no conversion would be necessary.

If that is true, then the task would be to find out why 39 i ...

LOL.

I remember those shoe x-ray machines - it was fun to watch as you wiggled your toes! Would have been in the late 1940's or early 1950s.

Those timing lights that are used to set engine timin ...

There are several other problems without looking at the code too closely.

1. The input to the timer 5 prescaler is Fosc/4 not Fosc.

2. T5 will overflow at low speeds. Define the minimum rotatio ...

For one device the address is not required. Either use the code in the link, or the code in the code library section of this forum. However, the code above should work with just one device connected. ...

I have tryed it but it is false with 18F4431. So I don't understand what must i do if i use 18F4431.

Are the AVdd and AVss pins connected?

AVdd to Vdd, and AVss to Vss.

Testing showed that the delay at the end of write_bit() wasn't critical within the specified timeslot width.
Had to be a long way outside the specified range before it st ...

Only thing I spotted was that the fuse should be XT instead of HS
for 4MHz.

It worked with the code 'as is' here

The counter will work in the range of 0 to 0xFFFF (65535). The range can be extended by sampling the count frequently, and adding the difference in sampled values between successive samples to a signe ...

The 16F88 has hardware for only an i2c slave (SSP) so it's bit banging I'm afraid.

The clock speed never reaches 100kHz regardless of the settings. With 8MHz it gets to about 83kHz, and when FAST = ...

The LM34 can go down to about 5F (-15C) without using a negative supply.
The sensitivity is 18mV/degree C (10mV/degree F by 9/5).

Could be a compiler bug. With version 4.084 the startup code clears all the ANSEL bits but the appropriate bit for the selected pin doesn't get set by setup_comparator().

As a work-around try

Yes. Counting occurs on the rising edge of the input though. I tested it on the 18F2520. If it's a reed switch then contact bounce could be a problem - should be easily fixed with a resistor and capac ...

I haven't used this chip, but here are a few things to check.

#define DAC 0x70

This implies the MAX5820L part with the Vadd pin connected to GND.
Confirm that the reference is connected. ...

It worked for me using a 16F876. A 16x2 lcd was connected to port B and the CCS driver lcd.c was used. Compiler version was 4.084.

I had to make changes. In FindDevices() the device number was disp ...

Very good

I will test it on hardware at work.
The lcd_init() statement should be before FindDevices() though.
