int digitalWriteAll(uint32_t value);
參數
[in] uint32_t value
This parameter is a 32-bit unsigned integer that specifies the value to be written to all digital output pins. Each bit in the value corresponds to a digital output pin of the EtherCAT slave device, with the following mapping:- Bit 0 indicates digital output pin 0.
- Bit 1 indicates digital output pin 1.
- And so on, up to bit 31 which indicates digital output pin 31.
A value of 1 typically sets the corresponding pin to HIGH, while a value of 0 sets it to LOW.
回傳值
Return an error code. If the returned value is zero, it indicates a successful execution of this function.
備註
This function must be called after a successful execution of EthercatMaster::start() and before EthercatMaster::stop(). This function is non-blocking and can be called within the callback functions.
範例
#include "Ethercat.h"
EthercatMaster master;
EthercatDevice_QECR00D88D slave;
void setup() {
master.begin();
slave.attach(0, master);
master.start();
}
void loop() {
slave.digitalWriteAll(0x55555555);
delay(1000);
slave.digitalWriteAll(0xAAAAAAAA);
delay(1000);
