14fc422mexcalcbits
Purpose Calculate parameter values for Fastcom 422/2-PCI board
Syntax MATLAB command line
[a b ] = fc422mexcalcbits(frequency)
[a b df] = fc422mexcalcbits(frequency)
Arguments
[a b] = fc422mexcalcbits(frequency) accepts a baud rate (in units of baud/
second) and converts this value into two parameters
a b. You must enter these
values for the parameter
Clock bits of the Fastcom 422/2-PCI driver clock. The
desired baud rate (
frequency) must range between 30e3 and 1.5e6, which is a
hardware limitation of the clock circuit.
[a b df] = fc422mexcalcbits(frequency) accepts a baud rate (in units of
baud/second) and converts this value into two parameters
a b. You must enter
these values for the parameter
Clock bits of the Fastcom 422/2-PCI driver
block. The third value,
df, indicates the actual baud rate that is created by the
generated parameters
a b. The clock circuit has limited resolution and is
unable to perfectly match an arbitrary frequency. The desired baud rate
(
frequency) must range between 30e3 and 1.5e6, which is a hardware
limitation of the clock circuit.
