= (**COPIED FROM ENGLISH PAGE**) === Action
Sends a value of a variable to the SPI-bus.
Syntax
SPIOUT var , bytes
Remarks
|
var |
The variable whose content must be send to the SPI-bus. |
|
bytes |
The number of bytes to send. Maximum value is 255. |
When SPI is used in HW(hardware) mode, there might be a small delay/pause after each byte that is sent. This is caused by the SPI hardware and the speed of the bus. After a byte is transmitted, SPSR bit 7 is checked. This bit 7 indicates that the SPI is ready for sending a new byte.

Dim A(10) As Byte Config Spi = Soft , Din =Pinb.0 , Dout =Portb.1 , Ss =Portb.2 , Clock =Portb.3 Spiinit Spiout A(1), 4 'write 4 bytes a(1), a(2) , a(3) and a(4) End
