Description:
write(byte value) method:
| Parameter | Description |
|---|---|
| value | data byte that should be sent |
The parameter value is a single byte which should be transmitted to the slave device.
write(byte[] buf) method:
| Parameter | Description |
|---|---|
| buf | data bytes that should be sent |
The parameter buf represents an array of bytes which should be transmitted to a specific slave device.
write(byte[] buf, byte register) method:
| Parameter | Description |
|---|---|
| buf | data bytes that should be sent |
| register | an extra byte is sent to the slave |
The parameter buf represents an array of bytes which should be transmitted to a specific slave device. Additionally, one extra byte is transmitted directly after the address byte. This is typically used to specify a slave device register where buf is to be written to.
write(byte[] buf, byte register, int offset, int len) method:
| Parameter | Description |
|---|---|
| buf | data bytes that should be sent |
| register | an extra byte is sent to the slave |
| offset | offset in buf array |
| len | number of the data bytes to be written |
The parameter buf represents an array of bytes which should be transmitted to a specific slave device. Additionally, one extra byte is transmitted directly after the address byte. This is typically used to specify a slave device register where buf is to be written to. The number of data bytes must be specified by the len parameter. The offset paramter specifies the offset in the buf array.
write(byte[] buf, int offset, int len) method:
| Parameter | Description |
|---|---|
| buf | data bytes that should be sent |
| offset | offset in buf array |
| len | number of the data byte |
The parameter buf represents an array of bytes which should be transmitted to a specific slave device. The number of data bytes must be specified by the len parameter. The offset paramter specifies the offset in the buf array.
write(byte[] buf, short register) method:
| Parameter | Description |
|---|---|
| buf | data bytes that should be sent |
| register | two extra bytes are sent to the slave |
The parameter buf represents an array of bytes which should be transmitted to a specific slave device. Additionally, two extra bytes are transmitted directly after the address byte. This is typically used to specify a slave device register where buf is to be written to.
write(byte[] buf, short register, int offset, int len) method:
| Parameter | Description |
|---|---|
| buf | data bytes that should be sent |
| register | two extra bytes are sent to the slave |
| offset | offset to the first data byte |
| len | number of the data byte |
The parameter buf represents an array of bytes which should be transmitted to a specific slave device. Additionally, two extra bytes are transmitted directly after the address byte. This is typically used to specify a slave device register where buf is to be written to. The number of data bytes must be specified by the len parameter. The offset paramter specifies the offset in the buf array.
Note
Example
The following example excludes the start() and stop() method calls which are required for an I2C communication.
byte[] data = {0x30, 0x40};
byte register = SI7021_READRHT_REG_CMD;
try
{
i2c.start();
i2c.write(data, register, offset, length);
i2c.stop();
}
catch(Exception exc)
{
Console.println(exc.getMessage());
}
The code above writes one extra byte to a specific slave device register after the address byte is sent. Afterwards two bytes are written to the same slave.
