Title: Intel_S1000 tests
|
|
|
|
Description:
|
|
|
|
This test illustrates the various features enabled on Intel_S1000.
|
|
|
|
Features exhibited in this test set
|
|
============================
|
|
|
|
GPIO toggling
|
|
- GPIO_23 configured as input
|
|
- GPIO_24 configured as output and interrupt capable
|
|
- GPIO_23 and GPIO_24 are shorted
|
|
- Upon toggling GPIO_23, GPIO_24 also changes state appropriately and
|
|
also calls its callback function if interrupt is configured
|
|
|
|
I2C slave communication
|
|
- Intel_S1000 I2C configured as master, 7 bit mode, standard speed
|
|
- 2 LED matrices are configured as slaves
|
|
- The LED matrices are written over I2C to emit blue light and red
|
|
light alternately
|
|
- Read functionality verified by reading LED0 after every write and
|
|
dumping the result on to the console
|
|
|
|
Interrupt handling
|
|
- All peripheral interrupts are enabled by default
|
|
- Each peripheral interrupt can be disabled by calling irq_disable().
|
|
For e.g. GPIO IRQ can be disabled by calling "irq_disable(GPIO_DW_0_IRQ);"
|
|
|
|
UART prints
|
|
- Displays the various prints dumped to the console by the above modules
|

Building and Running Project:
|
|
|
|
This project outputs to the console. It can be built and executed
|
|
on Intel_S1000 using the flyswatter2 as follows:
|
|
|
|
make flash
|
|
|
|
---------------------------------------------------------------------------
|
|
|
|
Troubleshooting:
|
|
|
|
Problems caused by out-dated project information can be addressed by
|
|
issuing one of the following commands then rebuilding the project:
|
|
|
|
make clean # discard results of previous builds
|
|
# but keep existing configuration info
|
|
or
|
|
make pristine # discard results of previous builds
|
|
# and restore pre-defined configuration info
|
|
|
|
