e) 如果使用programmer(例如usbasp)刷sketches到最小系统,注意每刷一次EEPROM都会被清除,解决的办法是将EESAVE熔丝位设置为1(见这个链接)。 f) 为了方便调试,以及解决programmer刷sketches导致EEPROM被清除的问题,我决定还是用ttl(pl2303)上传程序。连接好Vcc, Gnd, Tx, Rx后发现upload会失败,reset不起作用,在网上找...
read(). If you expect 16 bytes of data, you need to read(), successively, until you have received all 16. If you want to read until there is a newline, you will need to scan all characters until you find a newline -- and then save anything received after it for later.”来源...

EEPROM Depending on the board, the microcontroller on the Arduino board has 4 kilobytes, 1 kilobyte, or 512 bytes of EEPROM, which is permanent memory, like an extremely small little hard drive that you can save information to. So, how big is 512 bytes? It’s 128 integers, or 512 boole...
