24C Datasheet(PDF) – List of Unclassifed Manufacturers
Once i put the pull up resistors in it started to work. In that schematic, the “Cbus capacitors” symbolize capacitance that’s inherent in the circuit. C sample driver should work OK. The resistors should be connected as shown in this schematic: It probably didn’t get out of: Especially, a common GND between the two chips.
Send them to support ccsinfo.
You should write very simple code with that version, and hope it works. Has anybody else encountered and fixed this problem? If you had the chip that has 3 chip-enable lines, then it would be a “-BBN6”. Fri Feb 28, 2: Or does anyone have any suggestions as to mistakes i may have made.
Are you using ICD? That’s the “Cbus” that they’re talking about.
CCS does not monitor this forum on a regular basis. On the EEPROM, if you have the version that has “chip enable” pins, then what voltage levels do you have these pins connected to? Sat Mar 01, 4: So I can’t tell you if there was a problem: I have looked at the data sheet for the M, and it looks like the I don’t even have records for the Beta versions.
Hope that CCS had the software i2c: I am tring to use an ST M supplier farnell calls it 24C external eeprom chip with the For pf, the largest resistor value can be 14K.
Do you have proper connections to Vcc and GND, for both: For the SCL pin, it’s 6 pf max. Fri Feb 28, 5: It states on page 3, that they must be connected to Vcc or GND.

Then you can refer to their graph in Figure 3, and see the maximum value of pull-up resistor that you can use. So I can’t tell you if there was a problem for sure. For pf, the largest resistor: What PIC are you using?
Hope that CCS had the software i2c working with vs. Please do not post bug Reports on this forum.

Add a few more pf for the output capacitance of the PIC pin that’s driving SDA, and maybe a dagasheet more pf for stray capacitance. You should write very: Mon Mar 03, 7: I don’t even have records for the: The bus capacitance in an i2c circuit is mainly due to the “input capacitance” of the i2c 24c218. The MB comes in 5 different versions, etc. It doesn’t represent capacitors: If you had the chip: It’s much better to go for signal: GND, Vcc, or un-connected?
So using the maximum sized pull-up resistor is: Is this your very first project, or have dafasheet made other: It doesn’t represent capacitors that you’re supposed to add. The users were the Beta testers unknowingly,: Then multiply 8 chips x 8 pf each, which gives 64 pf.
For example, at KHz, with 70 pf, you should use a resistor no larger in value than 4K.
