Hello,

I'm using the same code with ISIS simulation. I have the file created but the data are "0000000000000".

Anybody have an idea?

Thanks.

Hello;
I'm working in a project with MMC SD and I use the ex_fat.c file but the simulation in isis doesn't work.

The used schematic is as follows:

//////////////////////////////////////////// ...

Thanks a lot Smile

I added the DEBUG to the fuses but I have the same result.

I use PICKIT3 as programmer (not debugger) but I have always the same result.

I use also:

#ASM ASIS
sleep
#ENDASM

But no re ...

Hello;
I want to put the 18f25k20 in sleep mode.
I use the following code.

#include "18f25k20.h"
#device PIC18f25k20
#fuses MCLR,INTRC_IO,PUT,NOWDT,NOLVP,NOBROWNOUT,BORV18,NOPROTEC ...

I get the correct i2c adresse but when reading data from the sensor I get always MSB = 0xFF and LSB = 0xFF.
I think the problem can be about the i2c speed.
the configuration is as follows:
Cpu clo ...

Yes thanks Smile

A very bad fault but ..
Hopefully now I can get the slave with the I2C scanner and I get something, not correct value, but I will try to find something.

Thank you

I tried the posted code but I have always 0x00 and 0x00 for the read values. And I should be sure of my hardware which is as follows:

I'm using 3K0 ohm pull-up resistors. So when I check the voltag ...

Thanks.

Do you think that I should make some configuration before getting the temperature value or it's normal to get directly the temperature value?

Thank you.
So here is my code:

// get the temperature of the object
float get_temperature(int OBJECT_AMBIENT_TEMPERATURE, int fahrenheit_celsius) {

double tempFactor = 0.02 ...

Thanks.

So now I'm using 2.2kohm and with the I2C scanner I get so many correct addresses. And when I run the temperature programm I get 0 as I posted previously.

Number of i2c chips found: 112 ...

Thank you.

I made some research and I find that there is some one who make this component working with 280 ohm resistor.
When I use 3.3k I have no result with the I2C scanner and with 2.2k I have ...

Thank you

Now when using the “i2c bus scanner” I can get as follows:

USED addr: 10
ACK addr: 10
USED addr: 12

USED addr: 14

The following the previous image from the datasheet, I think the correct values for the two pull ...

Thanks for your answers.
I used the”i2c bus scanner program”. But there is a problem here. When I put the SDA pin to ‘1’ I get with the voltage measurement 0.886 V which is not enough to get ...
