อันนี้เป็นตัวที่จำลองกับproteus ซึ่งก็ทามงานได้ปกติครับ

[kumnan]

ตอนที่ผมต่อจอมันจะมีแต่ไฟเเบ็คไลน์ติดอะครับ แต่มันไม่แสดงข้อความอะไรเลยครับรบกวนพี่ๆๆช่วยดูให้ผมหน่อยครับ

ขอบคุณครับ

[JUB]

ทดสอบโปรแกรมแค่จอ lcd ก่อน มีปัญหากันเยอะ เป็นไปได้เขียน library เองดีที่สุด

[kumnan]

ตัวนี้เป็น  liberty ของจออะครับ พี่ช่วยดูให้หน่อยนะครับ ว่ามีอะไรผิดไหมแต่ทำให้ proteus ก็ใช้งานได้ปกติ เลยงง มากครับ.....

เลือกใช้ osc ภายในหรือเปล่า ดูจากวงจรแล้วไม่ได้ต่อคริสตอล แม้ไม่ได้ต่อแต่โปรแกรม proteus ก็ยังซิมการทำงานได้ แต่วงจรจริงจะไม่ทำงาน
