#128676 - P89LPC936 I2C |
Hi, I need some help interfacing the Dallas DS1337 I2C Serial RTC to the LPC936. I have found the dta sheets for it at http://datasheets.maxim-ic.com/en/ds/DS1...S1337C.pdf and I also found Philips LPCXXX micro controller in I2C applications at http://www.nxp.com/acrobat_d...0155_1.pdf
I also have used the code architect page to generate the code for LPC936 I2C. I need to interface these two chips, but I need some help with it. At least some help in the first part after receiver/slave has been aknowledged and it is accesible. How can I write this part if I want to change (write) to some of the RTC registers. What would be the next step after the slave has been accessed with the start & stop conditions and the slave address? What is one good way to do this? Thanks a lot |

Here! | 01/01/70 00:00 | |
read the p89v66x datasheet and go through | 01/01/70 00:00 | |
What about this | 01/01/70 00:00 | |
the address issue ... | 01/01/70 00:00 | |
Don't shift | 01/01/70 00:00 | |
In other words if a slave uC (or some other | 01/01/70 00:00 | |

I do not handle bits, I write the SFR in one go | 01/01/70 00:00 | |
What is that? | 01/01/70 00:00 | |
sorry, SILABS SFR doing exactly the same | 01/01/70 00:00 | |

are you using a bondout? | 01/01/70 00:00 | |
Yes | 01/01/70 00:00 | |
try it the old fashioned way | 01/01/70 00:00 | |
OK | 01/01/70 00:00 | |
is this easier to understand? | 01/01/70 00:00 | |
