Original author: jees kim ## Components - **WIZnet WizFi360-EVB-Pico** x 1 - **SparkFun Pushbutton switch 12mm** x 3 ([docs](https://www.sparkfun.com/products/9190)) - Software: **Microsoft Azure IoT Hub** ([docs](https://learn.microsoft.com/en-gb/azure/iot-hub/)) - Software: **WIZnet WizFi360-EVB-Pico-AZURE-C** ([docs](https://github.com/Wiznet/WizFi360-EVB-Pico-AZURE-C)) ## Documents and links - [WizFi360-Pico SourceCode](https://github.com/jeesang7/WizFi360-EVB-Pico-C/tree/contest) (code): github - [LED & Push Switch for Pico](https://maker.wiznet.io/_lib/download.asp?path=project/7907&downfile=694844443%5F1666565789%2Epng) (schematics) ## Article ## Purpose Sometimes, I can't remember if I took the medicine, or I forget to take it at the desired time. Vitamins and blood pressure pills, have to take every day, but sometimes you forget and don't take them. Based on C language, It is a system that allows you to set the desired time and check whether you are taking the medicine. ## Design I was thinking about how to manage my morning, lunch, and dinner medications. We needed at least three containers, and we needed a way for each container to be identified by an alarm or indicator light. ![](https://maker.wiznet.io/upload/ckeditor5/1015660776%5F1666745175%2Ejpg) Especially, I planned to implement the function by controlling GPIO using wizfi360-pico. ## LED & Push Button By using the LED and button, you can store various medications and check whether they are taken or not. It is a simple operation process: If the LED is on, take your medicine. When you have taken your medicine, press the button to turn off the LED. For people who take various medications, 3 pairs of LEDs and buttons are configured as a controller. ![](https://maker.wiznet.io/upload/ckeditor5/267221056%5F1666440867%2Epng) First, configure a pair of LEDs and Buttons. ![](https://maker.wiznet.io/upload/ckeditor5/694844443%5F1666565789%2Epng) ![](https://maker.wiznet.io/upload/ckeditor5/694844443%5F1666565539%2Ejpg) ## Azure IoT Hub Using Azure IoT Hub, LED status can be checked remotely. Using Azure IoT Hub service, I connected my flask-based personal server. You can check the status of the WizFi360-Pico device anytime, anywhere by connecting to a smartphone through this server. ![](https://maker.wiznet.io/upload/ckeditor5/267221056%5F1666441381%2Epng) Guides and References for connecting to Azure IoT Hub can be found in the repository below: ## Debugging using picoprobe Debugging is possible using [picoprobe](https://github.com/raspberrypi/picoprobe) in Wizfi360-pico ! Also, I was able to debug using picoprobe in vscode, which I personally use. ![](https://maker.wiznet.io/upload/ckeditor5/1015660776%5F1666745758%2Ejpg) ![](https://maker.wiznet.io/upload/ckeditor5/369532972%5F1666939590%2EPNG) ## Without Azure I used another option for the Azure credit issue, refer to the link below: ![](https://maker.wiznet.io/upload/ckeditor5/694844443%5F1666560892%2Epng) This option can connect the server using TCP Socket communication without Azure. In macOS or Linux, you could check the sending/receiving of messages on the server simply by using [netcat(nc)](https://nc110.sourceforge.io/). ![](https://maker.wiznet.io/upload/ckeditor5/694844443%5F1666561458%2Epng) ## WizFi360-EVB-Pico-C You can refer to the following commit link for code changes: #### examples/TCP_Client_Demo/app_main.c ```c extern int32_t gpio_handler (void); ... static void app_medicbox (void *argument) { int32_t status; printf("GPIO control for MedicBox\r\n"); gpio_handler(); } ... void app_initialize (void) { ... osThreadNew(app_medicbox, NULL, &app_main_attr); } ``` I've added one more FreeRTOS task, that task allows you to control LEDs and buttons. #### examples/TCP_Client_Demo/iot_demo.c ```c ... #include "pico/stdlib.h" ... const uint BTN_PIN_1 = 13; const uint LED_PIN_1 = 14; const uint BTN_PIN_2 = 12; const uint LED_PIN_2 = 15; const uint BTN_PIN_3 = 9; const uint LED_PIN_3 = 10; ... int demo( void ) { ... while(1) { ... if(retval > 0){ ... if (strncmp(g_tcp_recv_buf, "ledon1", 6) == 0) { printf("receive ledon1 then gpio led1 on!\n"); gpio_put(LED_PIN_1, 1); } if (strncmp(g_tcp_recv_buf, "ledon2", 6) == 0) { printf("receive ledon2 then gpio led2 on!\n"); gpio_put(LED_PIN_2, 1); } if (strncmp(g_tcp_recv_buf, "ledon3", 6) == 0) { printf("receive ledon3 then gpio led3 on!\n"); gpio_put(LED_PIN_3, 1); } } } } int gpio_handler(void) { // #1 gpio_init(BTN_PIN_1); gpio_set_dir(BTN_PIN_1, GPIO_IN); // We are using the button to pull down to 0v when pressed, so ensure that when // unpressed, it uses internal pull ups. Otherwise when unpressed, the input will // be floating. gpio_pull_up(BTN_PIN_1); gpio_init(LED_PIN_1); gpio_set_dir(LED_PIN_1, GPIO_OUT); gpio_put(LED_PIN_1, 0); sleep_ms(1000); gpio_put(LED_PIN_1, 1); // #2 gpio_init(BTN_PIN_2); gpio_set_dir(BTN_PIN_2, GPIO_IN); gpio_pull_up(BTN_PIN_2); gpio_init(LED_PIN_2); gpio_set_dir(LED_PIN_2, GPIO_OUT); gpio_put(LED_PIN_2, 0); sleep_ms(1000); gpio_put(LED_PIN_2, 1); // #3 gpio_init(BTN_PIN_3); gpio_set_dir(BTN_PIN_3, GPIO_IN); gpio_pull_up(BTN_PIN_3); gpio_init(LED_PIN_3); gpio_set_dir(LED_PIN_3, GPIO_OUT); gpio_put(LED_PIN_3, 0); sleep_ms(1000); gpio_put(LED_PIN_3, 1); while (1) { if (gpio_get(BTN_PIN_1)) { printf("button1 pushed\n"); gpio_put(LED_PIN_1, 0); } if (gpio_get(BTN_PIN_2)) { printf("button2 pushed\n"); gpio_put(LED_PIN_2, 0); } if (gpio_get(BTN_PIN_3)) { printf("button3 pushed\n"); gpio_put(LED_PIN_3, 0); } sleep_ms(250); } } ``` When the 'ledon1' string is input in the *demo* function, the first led is turned on. The other two LEDs were processed in the same way. *gpio_handler* function initializes and sets gpio, I put it in a while loop to handle the button. If you have any questions about the above code, please leave your inquiry in the comments. ## Upcycling Medicbox is made using product packaging or plastic. It's not very beautiful to look at, but it's meaningful to be able to make new products using discarded things. ![](https://maker.wiznet.io/upload/ckeditor5/1015660776%5F1666743345%2Ejpg) ![](https://maker.wiznet.io/upload/ckeditor5/1015660776%5F1666743373%2Ejpg) And, because I made a product that is unique in the world, it is precious to me. ## Application In the app, you can simply check whether you are taking your medicine and set a reminder. ![](https://maker.wiznet.io/upload/ckeditor5/369532972%5F1666940099%2Ejpeg) ## Links [Embedded media](https://www.youtube.com/embed/WGAY_tN9-3o) - [hackster.io](https://www.hackster.io/jeesang-kim/medicbox-for-wizfi360-evb-pico-819608) - [Facebook](https://m.facebook.com/story.php?story_fbid=pfbid02N9FRNgr9sUurT32BijqGcEu2gwdQtfNwvogq3BA4L2kJCoGVD9fwZ8pqiyB1ozfWl&id=100029311451088) - [Instagram](https://www.instagram.com/p/CiprQg_vMxV/?igshid=YmMyMTA2M2Y=) --- Source: https://maker.wiznet.io/jeenowden/contest/medicbox-for-wizfi360-evb-pico/
