Command: > < data ... >
This command continues a write sequence in a new line.
<
data
…>
is a sequence of bytes that will be written in auto-increment mode. Each byte is in
hexadecimal format.
Command: # [optional comment]
This command indicates a comment.
Command: I < interface >
< interface > is i2c for I
2
C ™ or spi for SPI
Command: b[optional comment]
[optional comment] is a string of characters. The command interpreter will show a modal dialog with
the optional comment. Script execution will resume once the dialog is closed.
Command: d < time >
This command suspends script execution by at least < time > milliseconds.
Command: f < address > < register > < mask > [optional timeout]
This commands suspends script execution until the value read from
<
address
> <
register
>
matches
< mask >
< address > is the device address in hexadecimal format. For example, 30 for device address 0x30.
< register > is the register in hexadecimal format that will be read from.
< mask > is a 8-bit binary format mask that is compared with the data from the device. Each bit can be
0, 1, or X.
For example:
< mask > = 010XX01X tests, if the data from the device has D7 = 0, D6 = 1, D5 = 0, D4 =
don ’ t care, D3 = don ’ t care, D2 = 0, D1 = 1, D0 = don ’ t care.
[optional timeout] specifies how long (milliseconds) the command interpreter will poll the device if the
data do not match the
< mask >
