HI, I am new to LPC2129,

Is it possible to communicate thourgh serial i.e UART at a baud of 1,15,200. I have connected 12Mhz crystal to LPC2129 device.

I have searched in our yahoo group, but i could not find any sample code at a baud of 1,15,200.
Could please share some sample code for this, if you have any!!!

or please guide me how to this using above crystal. I am interested with this crystal only, because, again i wanted to use CAN nodes.

Plese suggest me.

Thanks and Regards

Hi Narayana,
 
Here is the link to the user manual of the controller:
http://ics.nxp.com/support/documents/microcontrollers/pdf/user.manual.lpc2109.lpc2114.lpc2119.lpc2124.lpc2129.lpc2194.lpc2210.lpc2212.lpc2214.lpc2220.lpc2290.lpc2292.lpc2294.pdf
 
See chapter 10 (on UART). Also carefully see the example given on page no.136 in the same chapter. It describes how to set up the UART at baud of (approx) 115200.
Hope it helps.
 
Regards,
Mayuresh Manjrekar

go to pudn.com , there you'll find sample uart code
that is perfectly working code.you need to change BAUD_RATE value

Hi,
using CAN and running at 115200 is only possible with the 2129/01 device. Make sure you have the /01 device. It has been the standard device for the last 2 years but if your board holds an older version, the required fractional baudrate generator is not implemented.
You need the fractional Baudrate Generator to achieve 115200.
