You could upgrade to a board with massive number of GPIO like the Grand Central, or you could pop on one of these boards. Connect it over I2C and then you can send/receive I2C commands to control the GPIO pins to write and read them. It's going to be slower than direct GPIO access, but maybe that doesn't matter if it takes a millisecond instead of a microsecond. You only need the two I2C pins, and you can even share the I2C port with other sensors and devices. Heck, you can even add more expanders for massive I/O control!.／GPIO擴充器的工作原理是這樣的：你有一個帶有一定數量的GPIO的電路板，但不足以滿足你的專案 - 也許你需要更多的按鈕或LED。您可以升級到具有大量GPIO的板，例如 Grand Central，或者您可以在其中一個板上彈出。通過 I2C 連接它，然後您可以發送/接收 I2C 命令來控制 GPIO 引腳以寫入和讀取它們。它將比直接GPIO訪問慢，但如果它需要一毫秒而不是一微秒，也許這並不重要。您只需要兩個I2C引腳，您甚至可以與其他感測器和設備共用I2C埠。哎呀，您甚至可以添加更多擴展器來實現大規模的I / O控制！。\n【The AW9523 is a twist on the common I2C expander】：    - First up, its very affordable - who doesn't love that?\n    - It has 16 I/O pins, that'll double most boards' pin count\n    - Four I2C address options, so you can connect 4 expanders to one bus\n    - Each pin can be an input or an output\n    - IRQ output can alert you when input pins change value\n    - This chip does not support internal pull-ups or pull-downs, you will need to add an external resistor if you...","shipping_methods":[{"name":"郵局掛號","fee":0,"currency":"TWD"},{"name":"7-ELEVEN取貨付款","fee":0,"currency":"TWD"},{"name":"7-ELEVEN取貨不付款","fee":0,"currency":"TWD"}],"lowest_shipping_fee":null,"payment_methods":["ATM轉帳","7-ELEVEN取貨付款"],"category_id":"2092072544","category_name":"其他電腦周邊","breadcrumb":[{"id":"23336","name":"電腦、平板與周邊","url":"/tw/%E9%9B%BB%E8%85%A6%E3%80%81%E5%B9%B3%E6%9D%BF%E8%88%87%E5%91%A8%E9%82%8A-23336-category.html"},{"id":"2092072522","name":"電腦/筆電周邊","url":"/tw/%E9%9B%BB%E8%85%A6-%E7%AD%86%E9%9B%BB%E5%91%A8%E9%82%8A-2092072522-category.html"},{"id":"2092072544","name":"其他電腦周邊","url":"/tw/%E5%85%B6%E4%BB%96%E9%9B%BB%E8%85%A6%E5%91%A8%E9%82%8A-2092072544-category.html"}],"view_count":0,"watch_count":0}
