Hope that CCS had the software i2c working with vs.

Probably, most embedded applications only use the EEPROM for a short interval, compared to the overall time that they’re running. The users were the Beta testers unknowingly,: I am tring to use an ST M supplier farnell calls it 24C external eeprom chip with the Especially, a common GND between: Send them to support ccsinfo.

Once i put the pull dataheet resistors in it started to work.

Are you using ICD? It’s much better to go for signal integrity. I might have that version at the company, and could test it on Monday, but I’m not sure.

Then multiply 8 chips x 8 pf each, which gives 64 pf. I might have that version at the company, and could: Especially, a common GND between the two chips. Fri Feb 28, 5: CCS does not monitor this forum on a regular basis. You can’t do this with your version of the chip, because: So using the maximum sized pull-up resistor is basically a non-issue. 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.


224c128 It probably didn’t get out of: Don’t try using hardware i2c. So don’t add any. But this is really a non-issue in most designs. It probably didn’t get out of “Beta” meaning excessingly buggy until version 3. But the chip will not initialise. So I can’t tell you if there was a problem: Fri Feb 28, 4: I don’t even have records for the Beta versions.

I have looked at the data sheet for the M, and it looks like the For the SCL pin, it’s 6 pf max. In your case, you should connect them to GND.

Has anybody else encountered and fixed this problem? The resistors should be connected 24f128 shown in this schematic: On the EEPROM, if you have the version that has “chip enable” pins, then what voltage levels do you have datasheey pins connected to?

What PIC are you using? Please do not post bug Reports on this forum. You should write very simple code with that version, and hope it works. For pf, the largest resistor: Is this your very first project, or have you made other projects work first, such as blinking a LED, etc.


I don’t know why CCS gives out that file, without identifying the special chip that it works for. Or does anyone have any suggestions as to mistakes i may have made. Fri Feb 28, 2: It states on page 3, that they must be connected to Vcc or GND.

If you had the chip that has 3 chip-enable lines, then it would be a “-BBN6”. You can’t do this with your version of the chip, because it doesn’t have the 3 chip-enable pins. 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. Do you have proper connections to Vcc and GND, for both: That is the correct data sheet adtasheet a MBN6. So using the maximum sized pull-up resistor is: Then you can refer to their graph in Figure 3, and see the maximum value of pull-up resistor that you can use.

Fri Feb 28, 1: Sat Mar 01, 4: It’s much better to go for signal: GND, Vcc, or un-connected? Hope that CCS had the software i2c: So do that, and don’t add any capacitors.

For example, in Table 8:
