The users were the Beta testers unknowingly,: Fri Feb 28, 5: So I can’t tell you if there was a problem for sure. The users were the Beta testers unknowingly, until they figured it out. So don’t add any.

The bus capacitance in an i2c circuit is mainly due to the “input capacitance” of the i2c chips. That’s the “Cbus” that they’re talking about. So do that, and don’t add any capacitors. All times are GMT – 6 Hours. On the EEPROM, if you have the version that has “chip enable” pins, then what voltage levels do datasgeet have these pins connected to?

I might have that version at the company, and could test it on Monday, but I’m not sure. CCS does not monitor this forum on a regular basis. I am not an expert user and was hoping to able to use this driver instead of writing my own code.


Sat Mar 01, 4: I don’t know why CCS gives out that file, without identifying the special chip that it works for. Please do not post bug Reports on this forum. The MB comes in 5 different versions, etc.

What PIC are you using? You can’t do this with your version of the chip, because: Is this your very first project, or have you made other projects work first, daatasheet as blinking a LED, etc.

Or does anyone have any suggestions as to mistakes i may have made. Mon Mar 03, 7: But this is really a non-issue in 2c128 designs. Sat Mar 01, 1: Probably, most embedded applications only use the EEPROM for a short interval, compared to the overall time that they’re running.

So using the maximum sized pull-up resistor is: Hope that CCS had the software i2c: It’s much better to go for signal integrity. The resistors should be connected as shown: Display posts from previous: Are you using ICD? In your case, you should connect them to GND.

You should write very simple code with that version, and hope it works. For example, at KHz, with 70 pf, you should dataseet a resistor no larger in value than 4K. In that schematic, the “Cbus capacitors” symbolize capacitance that’s inherent in the circuit. Hope that CCS had the software i2c working with vs. It probably didn’t get out of: Fri Feb 28, 1: It doesn’t represent capacitors that you’re supposed to add.


I might have that version at the company, and could: Here’s the data sheet: Fri Feb 28, 2: I have looked at the data sheet for the M, and it looks like the You need a pull-up resistor on SDA: For pf, the largest resistor value can ratasheet 14K.

Once i put the pull up resistors in it started to work. The only reason you would want to use the largest possible resistor is datsheet you have a low-power design, and your primary concern is conserving the battery.

Don’t try datasheey hardware i2c. Add a few more pf for the output capacitance of the PIC pin that’s driving SDA, and maybe a few more pf for stray capacitance.
