operating system and so that you can use the chip's UART for I/O. Please read

Examples
|
||||
========
|
||||
The port comes with two examples: A very basic example and a mode advanced one
|
||||
(web demo). The former demonstrates how to read sensors and how to use board
|
||||
peripherals. It also demonstrates how to send out BLE advertisements.
|
||||
The latter includes a CoAP server, an MQTT client which connects and publishes
|
||||
to the IBM quickstart service, a net-based UART and lastly a web server that
|
||||
can be used to configure the rest of the example.

Build your First Example
|
||||
------------------------
|
||||
It is recommended to start with the `cc26xx-demo` example under `examples/cc26xx/`. This is a very simple example which will help you get familiar with the hardware and the environment. This example can be used for the Sensortag and SmartRF06 EB.
|
||||
|
||||
Strictly speaking, to build it you need to run `make TARGET=srf06-cc26xx BOARD=srf06/cc26xx`. However, the example directories contain a `Makefile.target` which is automatically included and specifies the correct `TARGET=` argument. The `BOARD=` environment variable defaults to `srf06/cc26xx` (which is the SmartRF06 EB + CC26XXEM). Thus, for examples under the `cc26xx` directory, and when using the SmartRF06 EB, you can simply run `make`.
|
||||
|
||||
Other options for the `BOARD` make variable are:
|
||||
|
||||
* Srf06+CC26xxEM: Set `BOARD=srf06/cc26xx`
|
||||
* Srf06+CC13xxEM: Set `BOARD=srf06/cc13xx`
|
||||
* CC2650 tag: Set `BOARD=sensortag/cc2650`
|
||||
|
||||
If the `BOARD` variable is unspecified, an image for the Srf06 CC26XXEM will be built.
|
||||
|
||||
If you want to switch between building for one platform to the other, make certain to `make clean` before building for the new one, or you will get linker
|
||||
errors.
|
||||
|
||||
If you want to upload the compiled firmware to a node via the serial boot loader you need to manually enable the boot loader and then use `make cc26xx-demo.upload`. On the SmartRF06 board you enable the boot loader by resetting the board (EM RESET button) while holding the `select` button. (The boot loader backdoor needs to be enabled on the chip, and the chip needs to be configured correctly, for this to work. See README in the `tools/cc2538-bsl` directory for more info). The serial uploader script will automatically pick the first available serial port. If this is not the port where your node is connected, you can force the script to use a specific port by defining the `PORT` argument eg. `make cc26xx-demo.upload PORT=/dev/tty.usbserial`
|
||||
|
||||
Note that uploading over serial doesn't work for the Sensortag, you can use TI's SmartRF Flash Programmer in this case.
|
||||
|
||||
For the `cc26xx-demo`, the included readme describes in detail what the example does.
|
||||
|
||||
To generate an assembly listing of the compiled firmware, run `make cc26xx-demo.lst`. This may be useful for debugging or optimizing your application code. To intersperse the C source code within the assembly listing, you must instruct the compiler to include debugging information by adding `CFLAGS += -g` to the project Makefile and rebuild by running `make clean cc26xx-demo.lst`.

Sensortag vs Srf06
|
||||
==================
|
||||
To build for the sensortag, you will need to set the `BOARD` make variable as
|
||||
follows:
|
||||
|
||||
* Srf06+CC26xxEM: Set `BOARD=srf06/cc26xx`
|
||||
* Srf06+CC13xxEM: Set `BOARD=srf06/cc13xx`
|
||||
* CC2650 tag: Set `BOARD=sensortag/cc2650`
|
||||
|
||||
You can do that by exporting `BOARD` as an environment variable, by adding it
|
||||
to your Makefile or by adding it to your make command as an argument.
|
||||
|
||||
If the `BOARD` variable is unspecified, an image for the Srf06 CC26XXEM will be

built.
