สอบถามครับ ผมUpload Software serial examples ลงบอร์ด Arduino ไม่ได้ครับช่วยที

แล้ว blink sketch โหลดได้หรือเปล่าครับ

ได้ครับแต่พอปรับตรง delayจาก1000 เป็น100ก็ uploadไม่ได้ครับ

ไปที่เมนู file -> preference -> Show verbose output during: ให้ติ๊กถูกทั้งคู่ (compilation, upload) แล้ว paste error code เต็มๆ มาหน่อยครับ เปลี่ยนแค่ 1000 เป็น 100 ไม่น่ามีอะไรนะ

blink sketch compile ผ่านหมดแล้ว คงไม่ใช่ที่ sketch

error บอกว่า write files ลงบอร์ดสำเร็จ แต่พอ IDE อ่านค่ากลับขึ้นมา มันไม่ตรงกับค่าที่เขียนลงไปครับ อาการเหมือน eeprom มันมี defect คือเสียเป็นบางบิทไป

ขอ confirm อาการ เพราะผมสงสัยว่ามีอาจการไปโหลด sketch ที่มีการ block serial port ไว้หรือเปล่า ให้ไปที่ file -> preferences แล้วเอาติ๊กที่ช่อง verify after upload ออกครับ น่าจะ upload ได้ แล้วต้องไปลุ้นเอาว่า blink sketch จะรันได้หรือเปล่า

ลองโหลดหลายๆ sketch โดยเลือก sketch ที่ไม่ใช้ serial port ทำอย่างอื่นนอกจาก debug เท่านั้น

จากนั้น ให้ไปที่ file -> preferences แล้วเอาติ๊กที่ช่อง verify after upload กลับมาแล้วโหลด blink sketch อีกที ถ้ายัง error อยู่ ให้รอเจ้าองร้านกลับมา แล้วขอเคลมดีกว่าครับ eeprom อาจเสียบางบิต ซึ่งเกิดขึ้นได้ครับ

ปล. ช่วงนี้ upgrade Arduino IDE เป็น 1.8.1 ก่อนก็ดีนะ เผื่อมันเป็นบั๊กของ IDE ของผมลอง upload sketch ทั้งจาก IDE จากทั้ง web IDE ถ้าอาการเดียวกัน แสดงว่าน่าจะ hardware

ขอบคุณครับจะลองทำดูครับ

สรุปน่าจะเป็นที่บิตบางที่เสียครับขอบคุณมากๆครับที่ให้คำแนะนำดีๆแบบนี้ได้ความรู้หลายอย่างเลย

ไม่เป็นไรครับ อาการของคุณน่าจะเสียที่ bit 0 ของ byte 0x0072 เพราะมันบอกว่า 0x14 != 0x15 แสดงว่า bit 0 เขียน 1 อ่านได้ 0 ถ้า sketch ที่คุณใช้ เช่น blink delay 1000 เผอิญตำแหน่งนี้ใน hex file ดันเป็นค่า 0 พอดี มันก็จะ verify ผ่าน

ถ้ามี UNO อีกตัว จะลองเบิร์น bootloader ใหม่ดูก็ได้นะ เผื่อเกิดจาก bootloader มีคนเคยเจอว่าใช้ไปนานๆ write sketch ไม่เข้า burn bootloader ใหม่ก็หาย

ทำตามนี้ครับ https://learn.sparkfun.com/tutorials/installing-an-arduino-bootloader

ต่อตามรูปที่มี UNO 2 ตัวต่อกัน โดยตัวที่ดีเป็นตัวซ้าย

ตัวซ้ายต่อ USB เข้า PC เปิด IDE แล้วเลือก File -> Examples -> 11.ArduinoISP -> ArduinoISP จากนั้นโหลด ArduinoISP sketch เข้า UNO ตัวซ้าย

จากนั้นไปที่ IDE แล้วเลือก Tools -> Programmer:xxx -> Arduino as ISP มันมี ArduinoISP กับ Arduino as ISP นะ ให้เลือกอันหลัง อย่าเลือกผิด

ส่วน Tools -> Board:xxx เป็น UNO ถูกแล้ว เพราะคุณจะเบิร์น bootloader ของ UNO แล้วเลือก Tool-> Burn Bootloader เป็นอันเสร็จ

ถ้าไม่อยากเสี่ยง รอเจ้าของร้านก็ได้

ขอบคุณที่ช่วยแชร์ครับ

ใช่ครับ อาการนี้ ลองลง bootloader ใหม่อาจจะแก้ได้ครับ

เเล้วเป็นบอร์ดMega2560 ต้องเเก้ยังไงค่ะ
