This article is to record the Amoy to a treasure no one on the history of the development of nano board of the bootloader (relatively pit), its own search for information and records .
If there is no bootloader, the board can not receive the uploaded program, can not do anything.
Writing bootloader There are many ways, just to record a uno board as nano board programming bootloader example, I own is to use this approach:
Directly on the map:
1. First, bring up the bootloader program
2. And then the bootloader program uploaded to the board uno yard:
3. After successful upload, start wiring, and the connecting plate uno nano plate, corresponding to the following interfaces:
You can refer to this article:
Arduino bootloader programming
Too lazy to look, I have also compiled under:
4. Burn before, first set the following parameters:
5. Finally, click Burn, success!
6. Burn completed, the next test yourself, see if you can pass the program nano board, or the simplest test, can take advantage of nano port led lights lit, finally get.
7. If, on the hand there is no ready uno development board, then scouring a downloader, the program will burn to nano development board, after all, cheaper than a downloader uno board, only about 10 ocean, I have not tried this method , the link below for reference:
