Serial.write and Serial.print do not block. Older versions of Arduino would wait until all characters were sent before returning. Instead, characters that you send using Serial.write or Serial.print (and println) are transmitted in the background (from an interrupt handler), allowing your sketch...
int iRCspeed = atoi(RCspeed); // convert string into integer //rest of program } Android 应用程序发送的字符串被读入一个特殊的字符串结构:一个带有 null-termination 的 C 字符串。(0 字符告诉程序它已经到了字符串的末尾)。这是通过使用函数 Serial.readBytesUntil(‘\n’, input, 。..)来完成的...
