Subbed ! Fascinating as I was unaware you could read the Arduino in fact most people say to you can't. I suppose you can only get the Hex File and not disassemble it but i will have a copy of AVRDudess in my toolbag....cheers!!
10uF cap needed only for Nano as programmer? That was not made clear. I am using an Uno as programmer. Complete failure and frustration until I removed it.
mistakes can happen anytime with Arduino ISP. i use just USBasp, there will be a very visible difference between Arduino and USBasp, so, lower chance to make that nice mistake programming your ISP with the new sketch! :) (old USBasp, based on atmega8. newer versions can have a 328, too!)
Thank you for your suggestion, I agree that a USBASP must be more reliable. But most makers have Arduino's lying around so it is easier to start without ordering anything. I always use a (soldered) Arduino as ISP, but after your comment I consider to buy a USB ASP myself and check it out ;-)
Hi Andi, if you do NOT select the "Set Fuses" or "Set Lock" you do not need to worry, they will not be changed. Suggest you try with NOT selecting them.
@@smartpowerelectronics8779 okay thank you sir, if it turns out that the file requires fusebit and I still upload the eeprom&hex file? what will happen?&for example if I set the wrong fuse bit, how do I fix it
Normally the eeprom is not used, only if you have a sketch that saves into the eeprom. If you are not sure, just extract the eeprom hex and with a text editor see if it has data🙂
Hi by doing these clones is this copying all settings like code and fuse bits ? I need to find out the fuse settings on the atmega 328p-Au chip . So it seems by cloning this is achieved. 👍
Tried that and it works: Select "write" at flash (leave file/path blank) Select "erase fash and EEPROM then click the "Program!" button And your arduino will be erased. (by the way default baud rate is 19200, had that set wrong when I tried ;-))
I think that will work the same, (I do not know if the programmer sketch runs on a Leaonardo though, maybe you need an Uno or Nano for that) see also this video - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-YtE7PHuo504.html
You can use the arduino as ISP according to this website: wolles-elektronikkiste.de/en/lgt8f328p-lqfp32-boards Also MCUDUDE(SS) supports the lgt8f328p168P and 88P , you can find them all the way at the bottom of the "select MCU" drop down list, so I suggest you give it a try to read out the HEX. Will you let me know if this works? I never heard of the lgt8f328p before your question 🙂
This is a connection problem which can have many causes, please try: *Is the COM port correct? *Is the USB cable a data cable? *Did you install the USB-serial drivers (Chinese clone CH340?) check in Windows device manager...
