GPIO_16 is on IO8 * 2. GPIO_19 is on IO4 * * The gpio_dw driver is being used. * * This sample app toggles GPIO_16/IO8. It also waits for * GPIO_19/IO4 to go high and display a message. * * If IO4 and IO8 are connected together, the GPIO should * triggers every 2 seconds. And you should see this repeatedly * on console: * " * Toggling GPIO_16 * Toggling GPIO_16 * GPIO_19 triggered * " * * Arduino 101 - Sensor Subsystem * ------------------------------ * * On Sensor Subsystem of Arduino 101: * 1. GPIO_SS[ 2] is on A00 * 2. GPIO_SS[ 3] is on A01 * 3. GPIO_SS[ 4] is on A02 * 4. GPIO_SS[ 5] is on A03 * 5. GPIO_SS[10] is on IO3 * 6. GPIO_SS[11] is on IO5 * 7. GPIO_SS[12] is on IO6 * 8. GPIO_SS[13] is on IO9 * * There are two 8-bit GPIO controllers on the sensor subsystem. * GPIO_SS[0-7] are on GPIO_0 while GPIO_SS[8-15] are on GPIO_1. * * The gpio_dw driver is being used. The first GPIO controller * is mapped to device "GPIO_0", and the second GPIO controller * is mapped to device "GPIO_1". * * This sample app toggles GPIO_SS_2/A0. It also waits for * GPIO_SS_3/A1 to go high and display a message. * * If A0 and A1 are connected together, the GPIO should * triggers every 2 seconds. And you should see this repeatedly * on console (via ipm_console0): * " * Toggling GPIO_SS_2 * Toggling GPIO_SS_2 * GPIO_SS_3 triggered * " * * Arduino Due * ----------- * * On Arduino Due: * 1. IO_2 is PB25 * 2. IO_13 is PB27 (linked to the LED marked "L") * * The gpio_atmel_sam3 driver is being used. * * This sample app toggles IO_2. It also waits for * IO_13 to go high and display a message. * * If IO_2 and IO_13 are connected together, the GPIO should * triggers every 2 seconds. And you should see this repeatedly * on console: * " * Toggling GPIO_25 * Toggling GPIO_25 * GPIO_27 triggered * " * * Quark D2000 CRB * --------------- * * In order to this sample app work with Quark D2000 CRB you should * use a "jumper cable" connecting the pins as described below: * Header J5 pin 9 * Header J6 pin 7 * * If the app runs successfully you should see this repeatedly on * console: * " * Toggling GPIO_8 * Toggling GPIO_8 * GPIO_24 triggered * " */ #include <zephyr.h> #include <misc/printk.h> #include <device.h> #include <gpio.h> #include <misc/util.h> #if defined(CONFIG_SOC_QUARK_SE_C1000_SS) #define GPIO_OUT_PIN 2 #define GPIO_INT_PIN 3 #define GPIO_NAME "GPIO_SS_" #elif defined(CONFIG_SOC_QUARK_SE_C1000) #define GPIO_OUT_PIN 16 #define GPIO_INT_PIN 19 #define GPIO_NAME "GPIO_" #elif defined(CONFIG_SOC_ATMEL_SAM3) #define GPIO_OUT_PIN 25 #define GPIO_INT_PIN 27 #define GPIO_NAME "GPIO_" #elif defined(CONFIG_SOC_QUARK_D2000) #define GPIO_OUT_PIN 8 #define GPIO_INT_PIN 24 #define GPIO_NAME "GPIO_" #endif #if defined(CONFIG_GPIO_DW_0) #define GPIO_DRV_NAME CONFIG_GPIO_DW_0_NAME #elif defined(CONFIG_GPIO_QMSI_0) && defined(CONFIG_SOC_QUARK_SE_C1000) #define GPIO_DRV_NAME CONFIG_GPIO_QMSI_0_NAME #elif defined(CONFIG_GPIO_QMSI_SS_0) #define GPIO_DRV_NAME CONFIG_GPIO_QMSI_SS_0_NAME #elif defined(CONFIG_GPIO_ATMEL_SAM3) #define GPIO_DRV_NAME CONFIG_GPIO_ATMEL_SAM3_PORTB_DEV_NAME #else #define GPIO_DRV_NAME "GPIO_0" #endif void gpio_callback(struct device *port, struct gpio_callback *cb, uint32_t pins) { printk(GPIO_NAME "%d triggered\n", GPIO_INT_PIN); } static struct gpio_callback gpio_cb; void main(void) { struct device *gpio_dev; int ret; int toggle = 1; gpio_dev = device_get_binding(GPIO_DRV_NAME); if (!gpio_dev) { printk("Cannot find %s!\n", GPIO_DRV_NAME); return; } /* Setup GPIO output */ ret = gpio_pin_configure(gpio_dev, GPIO_OUT_PIN, (GPIO_DIR_OUT)); if (ret) { printk("Error configuring " GPIO_NAME "%d!\n", GPIO_OUT_PIN); } /* Setup GPIO input, and triggers on rising edge. */ ret = gpio_pin_configure(gpio_dev, GPIO_INT_PIN, (GPIO_DIR_IN | GPIO_INT | GPIO_INT_EDGE | GPIO_INT_ACTIVE_HIGH | GPIO_INT_DEBOUNCE)); if (ret) { printk("Error configuring " GPIO_NAME "%d!\n", GPIO_INT_PIN); } gpio_init_callback(&gpio_cb, gpio_callback, BIT(GPIO_INT_PIN)); ret = gpio_add_callback(gpio_dev, &gpio_cb); if (ret) { printk("Cannot setup callback!\n"); } ret = gpio_pin_enable_callback(gpio_dev, GPIO_INT_PIN); if (ret) { printk("Error enabling callback!\n"); } while (1) { printk("Toggling " GPIO_NAME "%d\n", GPIO_OUT_PIN); ret = gpio_pin_write(gpio_dev, GPIO_OUT_PIN, toggle); if (ret) { printk("Error set " GPIO_NAME "%d!\n", GPIO_OUT_PIN); } if (toggle) { toggle = 0; } else { toggle = 1; } k_sleep(MSEC_PER_SEC); } } |
