hello sir,

i am using uart using linflex on mpc5606b in codewarrior

data is not being transmitted ??

BELOW IS MY CODE

please reply ASAP

THANKYOU,,,

Hi,

attached you will find two working examples.

UART is also used in this example:

Example MPC5604B PinToggleStationery CW210

Regards,

Lukas
