UART1不能用于接收数据,因为通常它的RX引脚被用于闪存芯片连接。要使用Serial1,需要配置Serial1.begin(baudrate)。 如果未使用Serial1并且未交换Serial-UART0的TX可以通过在Serial.begin之后调用Serial.set_tx(2)或直接通过Serial.begin(baud,config,mode,2)将UART0的TX引脚映射到GPIO2(D4)。 默认情况下,...

Another point about changing the baud rate settings in board.txt... make sure you close out ALL instances of the Arduino IDE before editing. I edited boards.txt while the IDE was open and the change never appeared. Only after I closed the IDE, edited boards.txt then reopened the IDE was...
UI_ACTION_MOVE_ACCEL_Z : Change z acceleration during moves UI_ACTION_MAX_JERK : Change jerk value UI_ACTION_MAX_ZJERK : Change z-jerk value UI_ACTION_BAUDRATE : Change baudrate. Works only after storing to eeprom and reset! UI_ACTION_HOMING_FEEDRATE_X : Change x homing feedrate UI_...
CHANGE:改变沿,引脚电平从低变为高或者从高变为低时触发中断。 RISING:上升沿,引脚电平从低变为高时触发中断。 FALLING:下降沿,引脚电平从高变为低时触发中断。 返回值: 无; 2.detachInterrupt() 该功能用于禁用指定GPIO引脚上的中断。 函数: detachInterrupt(pin) 参数: pin:要禁用的中断的GPIO引脚。 返回值:...

It uses the accumulated value to set the blink rate. Note The newline character (ASCII value 10) can be appended automatically each time you click Send. The Serial Monitor has a drop-down box at the bottom of the Serial Monitor screen (see Figure 4-1); change the option from “No ...
