Quick start « shield »

The ACW-RPI shield is intended to be plugged on raspberry-pi board. The communication

with the shield is done by UART interface, there are both ways to do this: directly through the AT

command or by an application programming interface ARMAPI.

Notes : From Raspberry PI 3 model, a special configuration is required to access UART. Make sure to follow

the guide in annex to make the UART work properly.

The RESET pin of the shield is connected to the radio module RESET pin. By default, the pin

is LOW which force the module to reset. To enable the radio module, you must drive the GPIO4 of the RPI

to HIGH (see Annex for instructions).

The ACW-RPI shield support the ARM-NANO module (ARM-Nx-xx) from ATIM. Please see

the 'RF Modules' section of 'Documentation' page from

documentation about the module.

A C and C++ API (ARMAPI) is freely available on github

http://atim-radiocommunications.github.io/armapi/. You will find the examples and the documentation of

API. For raspberry-pi use the unix port (armport_unix.c). The hierarchy of API is show below:

Notes: Starting from Raspberry PI 3 model, the UART interface /dev/ttyAMA0 is no longer applicable.

Instead use /dev/ttyS0
