Flexbus K63 controller

vinaysb — Wed, 02 Dec 2015 17:42:07 GMT

Hi All,

We are using Flexbus to interface to an LCD. LCD is addressed using one bit Addr0. CS2 is used for LCD.

WE found that using logic analyzer. Addr0 is getting deasserted before the CS2 is getting asserted due to which LCD is not getting the Command.

Could some help us to identify the issue and fix the problem.

Thanks

Vinay S B

Hi Vinay,

please take a look on the Flexbus examples I attached to this post FlexBus in 16 bit mode and 8 bit access

They are usingK60 and K70 with CW and KDS. Some of the examples use TWR.LCD. They have also a document explaining the examples.

You may also take a look to AN4393
