I am implementing a communication between MSP430F169 with a temperature sensor TMP275. How do I monitor data(traffic) from the temperature sensor (slave) to the MSP430(master), which is in this case, data on the SDA line ?
I heard we can use PC’s Hyper terminal to read. Is this right ?
Thanks
Hi Oaranger,
have a look at Elektor’s March or April issue, ther was an article about an I2C monitor built around a PIC micro. I hope it helps.
I also remember a simple circuit wich connect I2C to the PC’s serial or parallel port, but currently I can’t fined the link. I’ll have a look at it at home and post it if You interested.
Best wishes,
Blaise
I took a look but couldnt find the article. And what about the circuit you have? Can you help me looking for it. THanks
Sorry, it was really late when I finally got home yesterday. Here is the link to the article in Elektor’s March issue. http://www.elektor-electronics.co.uk/ma … 2538.lynkx
I’ll look trough my saved links to find the other circuit I have mentioned in my former post.
If You visit FTDI’s web page (http://www.ftdichip.com) there is an example about using MPSSE mode of FT2232 to implement an USB-I2C interface. Have a look at the following link: http://www.ftdichip.com/Projects/MPSSE.htm#I2C
There is a ready made module available for evaluating the FT2232 chip which You can easily use. http://apple.clickandbuild.com/cnb/shop … DLP2232M-G

Finally I have found the link mentioned earlier. There is a solution to connect an I2C EEPROM to the PC’s RS232 port.
Best wishes,
Blaise
Blaise,
Can you post the links for us?
Eric
Oops, I have forgotten to paste it. Really sorry.
This is the link I have: http://www.scienceprog.com/rs232-emulat … g/#article
I hope You can use it somehow.
Best regards,
Blaise
