Prototype
sub function Soft_UART_Read(dim byref error as byte) as byte
Returns Byte received via UART.
Description
The function receives a byte via software UART.
This is a blocking function call (waits for start bit). Programmer can unblock it by
calling Soft_UART_Break routine.
Parameters :
-
error: Error flag. Error code is returned through this variable.
- 0 - no error
-
1 - stop bit error
- 255 - user abort, Soft_UART_Break called
Requires
Software UART must be initialized before using this function. See the
Soft_UART_Init routine.
Example
dim data as byte
error as byte
...
' wait until data is received
do
data = Soft_Uart_Read(error)
loop until (error = 0)
' Now we can work with data:
if (data) then
...
end if
