TiniArm SPI

[ddupont]

Can anybody tell me how fast the SPI communication port on the TiniArm is capable of clocking data out?

Thanks in advance for any replies

From the Phillips LPC210x document,

Maximum data bit rate of one eight of the input clock rate.

The SPI rate may be calculated as: PCLK rate / SPCCR value. The PCLK rate is CCLK/VPB divider rate as determined by the VPBDIV register contents.
