ดองใว้นาน!!! ตัวหยอดเหรียญ ตอนนั้นซื้อมา 20 บาท ที่ตลาดเซพวัน ดองจนลืม วันนี้จับมาปัดฝุ่น เลยเอามาต่อ MCU เล่น แต่ก็คิดไม่ออกว่าจะทำอะไร จึงจับรวมกับ GPS และ จอ 3310 เป็น GPS หยอดเหรียญ
จากรูปที่สอง เป็นรูปที่ยังไม่หยอดเหรียญ เมื่อหยอดแล้วจะได้รูปที่สามครับ พร้อมทั้งนับเวลาถอยหลังเป็นวินาที (บันทัดสุดท้ายของรูปที่สาม) ซึ่งการเช็คหยอดเหรียญนั้น เช็คแบบ Interrupt ทำให้สามารถหยอดเหรียญได้อย่างต่อเนื่อง การนับถอยหลังก็นับเวลาจากฐานเวลา GPS ซึ่งก็เดินตรงดี แถมด้วยเวลา GPS หลุด(จับดาวเทียมไม่ได้)ก็จะหยุดทำการนับเวลาถอยหลังด้วย เมื่อสัญญานมาก็จะทำการนับถอยหลังต่อ ทำให้ผู้ใช้บริการไม่ขาดทุนได้ข้อมูลตามที่จ่ายเงิน ไม่เอาเปรียบผู้บริโภค เอิ๊กๆ ขนาดจำลอง เล่นเอาซะเต็มที่เลย จากการทดลองนี้ทำให้ข้าพเจ้า ได้ศึกษาและเรียนรู้การติดต่อเครื่องหยอดเหรียญกับไมโครคอนโทรลเลอร์ ( หลอกเครื่องหยอดเหรียญไม่ได้ ) มันมีวงจรเช็คน้ำหนักแบบไม่ต้องช่างน้ำหนักได้ด้วย เก่งจริงๆ ขนาดรุ่นเก่านะนี่ ถ้ารุ่นใหม่ หมดสิทธิหลอกเครื่องแน่นอน
โค๊ดครับ
