Hi all,
Anyone some advice or experience on calculating the Xtal freq for a LPC22xx ARM7.
I just don't find a correct value to generate stnadard UART baudrates (9600, 19200, 38400..) and standard CAN-bus speeds (125,250,500,1000)
At this moment i have a 17.456MHz Xtal and this is working fine for the UART.
For the CAN-bus, a multiple of 8Mhz should work fine.
I tried to get to a compromis by changing PLL and Peripheral clock speeds, but it seems that there is no value that would exactly meet both requirments.
Any suggestions on how to find the right frequency ?
Thanks
Stan
