| 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 |
| |

| ***** BOOTING ZEPHYR OS v1.9.99-intel_internal - BUILD: Oct 31 2017 14:48:57 ***** |
| Sample app running on: xtensa Intel_S1000 |
| Reading GPIO_24 = 0 |
| LED0 = 10 |
| GPIO_24 triggered |
| Reading GPIO_24 = 1 |
| LED0 = 41 |
