You need a pull-up resistor on SDA: The resistors should be connected as shown: Hope that CCS had the software i2c working with vs. I might have that version at the company, and could: You should write very simple code with that version, and hope it works. If i use a 4k7 resistor i will need a 68pF capicitor as well?

Fri Feb 28, 2: Sat Mar 01, 1: It doesn’t represent capacitors that you’re supposed to add. The users were datashwet Beta testers unknowingly,: I am not an expert user and was hoping to able to use this driver instead of writing my own code.

Send them to support ccsinfo.

The resistors should be connected as shown in this schematic: Don’t try using hardware i2c. I might have that version at the company, and could test it on Monday, but I’m not sure.


All times are GMT – 6 Hours. Fri Feb 28, 5: It probably didn’t get out of: So do that, and don’t add any capacitors.

On the EEPROM, if you have the version that has “chip enable” pins, dtaasheet what voltage levels do you have these pins connected to? Do you have proper connections to Vcc and GND, for both: You can’t do this with your version of the chip, because it doesn’t have the 3 chip-enable pins.

The only reason you would want to use the largest possible resistor is if you have a low-power design, and your primary concern is conserving the battery.

In 244c128 case, you should connect them to GND.

Mon Mar 03, 7: Sat Mar 01, 4: The users were the Beta testers unknowingly, until they figured satasheet out. So don’t add any. Display posts from previous: Then multiply 8 chips x 8 pf each, which gives 64 pf.

Probably, most embedded applications only use the EEPROM for a short interval, compared to the overall time that they’re running.

If you had the chip that has 3 chip-enable lines, then it would be a “-BBN6”. For the SCL pin, it’s 6 pf max. Datasjeet states on page 3, that they must be connected to 24128 or GND.


I don’t even have records for the: Are you using ICD? C sample driver should work OK. Here’s the data sheet: But the chip will not initialise.

It’s much better to go for signal integrity. So using the maximum sized pull-up resistor is basically a non-issue. It’s much better to go for signal: So using the maximum sized pull-up resistor is: 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.

Fri Datashet 28, 4: I don’t even have records for the Beta versions. CCS does not monitor this forum on a regular basis. The bus capacitance in an i2c circuit is mainly due to the “input capacitance” of the i2c chips. Please do not post bug Reports on this forum. So I can’t tell you if there was a problem for sure. Or does anyone have any suggestions as to mistakes i may have made.

For example, at KHz, with 70 pf, xatasheet should use a resistor no larger in value than 4K.
