Alright then...

if I use this:

setup_adc_ports(AN0_TO_AN8 | VSS_VDD);
setup_adc(ADC_CLOCK_DIV_32|ADC_TAD_MUL_0);

can I still use ports between AN5 and AN8 for let's a LCD or are they l ...

// Constants used in SETUP_ADC_PORTS() are:
#define NO_ANALOGS 0x0F // None
#define ALL_ANALOG 0x00 // A0 A1 A2 A3 A5 E0 E1 E2 B1 B4 B0
#define AN0_TO_AN9 0x05 // A0 A1 A2 A ...

I need to use ADC channels AN0 to AN5 and AN8. I will be sampling between VSS(GND) and VDD(5V). The other "pins" need to stay digital. How would my setup_adc_ports() look like?

Thanks. :w ...

....I need to use 2 discrete N-channel enhancement MOS-FETs. Any available in through-hole?

2N7000.Alright well we don't have 2N7000s here so I went with an IRF520.

As for the 4 pull ups, what s ...

Why do you not want to follow the earlier suggestion of the typical way to hook 3.3V I2C and 5V I2C devices together? A search will turn up the document from NXP or others, it is simply 2 mosfets and ...

Why do you have the 5v side powered through a 200k resistor?
Well because that's the way its wired in the datasheet typical application example.

I am still having problems communicating with my se ...

Thanks for replying. Smile

Everywhere I look the microcontroller is on the 3.3V side and the sensor on the 5V side. Me it's the other way around. Everything except the sensor is running at 5V, this i ...

There is a 2000Ohm impedance between each line and the ground.

Is it normal for the PCA9306 to become really hot during operation?

Here is the schematic:

Well I already have the PCA9306.

But looking at the datasheet it would seem that the PIC must be 3.3V and the sensor 5V and not the other way around(the way I have it now).

I have a I2C pressure sensor that I wish to read using a PIC18F4685. The sensor runs at 3.3V and the PIC at 5V. I'm using the PCA9306 as a voltage-level translator. Will this setup work?

Thanks. :w ...

var % 10
that's the module(remaining) of var/10
so for example:

N = 185
N/10 = 18
N%10 = 5

so (18*10) + 5 = 185
Ah, ok now I understand. Thanx for clearing that up. Smile

I'm currently in the middle of converting a C program written for another type of micro controller to PICC. Everything is going quite smoothly except that now I'm stuck at this line of code:

Thanx for the reply. After discussing it with one of my teachers, he recommended I use a PCA9306, which is a I2C level translator.
