sendBit()
描述
將引數以位元設定至 ModbusMasterNode
類別中的私有陣列 writeData
中,並自動堆疊資料,和 beginTransmission 與無參數的 writeMultipleCoils 搭配使用。
writeData
是使用 Write 功能碼的 Modbus 封包內容。
語法
node1.sendBit(value)
參數
node1
: ModbusMasterNode
物件。
value
:填入 writeData
陣列的布林值,即欲傳送的 Modbus 封包內容。
範例
#include <Modbus86.h> ModbusMaster bus1; ModbusMasterNode node1; uint8_t result; void setup() { while(!Serial); bus1.begin(MODBUS_RTU, Serial1); node1.attach(16, bus1); node1.beginTransmission(5); node1.sendBit(true); node1.sendBit(false); result = node1.writeMultipleCoils(); if (result != MODBUS_SUCCESS) { Serial.print("ErrorCode: "); Serial.println(result); } } void loop() { }
