How to configure IO registers in BCM20737

[Anonymous]

I used to use AVR then, recently begin to use Broadcom's BLE module "BCM20737S".

But I don't get how to configure IO register's(ex.gpio,pwm,a/d converter) in BCM20737S. What document can I refer ?

I don't know why, but they aren't exist in datasheet...

Have you read the Hardware Interfaces Document?   WICED™ Smart Hardware Interfaces

Access to the low level I/O registers is usually not possible, as BCM has created an abstraction layer on top of them and provided the APIs to ask the hardware to do the work.

embeddedmasters has done an excellent job explaining how to configure GPIO on our part within the datasheet for their Embedded Masters Break-Out Board: http://www.cdiweb.com/datasheets/embedded/EMRF-BCM20736S-BOB-UserManual.pdf

Start on page 49.

In addition, the new Smart Designer feature in SDK 2.X can also be used to setup GPIO.

j.t put together an excellent 'How-To' video here: WICED Smart Video BLOG: SDK 2.1 Smart Designer Tool Walk-Thru

When using this tool, pay particular attention to the "To-Do' list as these are sections of code that still need to be manually programmed.  Smart Designer does the rest.
