StrobeWrites

Write 8-bit bytes to a port and strobe a control line

VERSION 1.34+ of the firmware, VERSION 42+ of the DLL

Description:

Strobe write of a 1 to 6 byte value to a port. This command uses port A or B for the written byte, as well as a polarity (negative or positive) and a line (A.0 – B.7) to toggle based on the previously executed StrobeWrite or StrobeRead call.

Command Syntax: (USBm.dll)

USBm_StrobeWrites( device, countarray, dataarray )

The USBm_StrobeWrites function syntax has these parts:

Part	Description
device	A zero-based index to address the appropriate USB device.
countarray	Byte array with the number of bytes (1-6) to send, and where the returned number of bytes will be stored. Minimum size of the array must be 1 byte
dataarray	Data to send. A byte array where the transmitted⁄received data will be stored. Minimum size of the array must be 6 byte

Remarks:

Control this command’s port for the byte, polarity and strobe line by using the StrobeWrite or StrobeRead call.

VB Declaration

Public Declare Function USBm_StrobeWrites _
    Lib “USBm.dll” _
        (ByVal device As Byte, _
        ByRef countarray As Byte, _
        ByRef dataarray As Byte) _
    As Integer

VB Example

Dim countarray(1) As Byte
Dim dataarray(6) As Byte
    countarray(0) = &H03
    dataarray(0) = &H55
    USBm_StrobeWrites 6, countarray(0), dataarray(0)

Control this command’s port for the written byte, polarity and strobe line by using the StrobeWrite or StrobeRead call. This command will then use the same selected port, polarity, and strobe line to write three bytes from dataarray to device number six.

C Prototype

int USBm_StrobeWrites( unsigned char device, unsigned char *count, unsigned char *data );

C Example

RobotBASIC

usbm_StrobeWrites(ne_DeviceNumber,se_ByteData)

Returns true if successful, false otherwise. Writes multiple bytes (1 to 6) to a port based on a strobing line and timing. the byte data string specifies the setup and the data to be written.

Raw Command Format:

Byte Number	Description
0	0Dh: StrobeWritesCmd
1	Number of Bytes (1-6)
2	Byte 1
3	Byte 2
4	Byte 3
5	Byte 4
6	Byte 5
7	Byte 6

Raw Command Format Details:

Byte 0 contains the command. Byte 1 is the number of data bytes to write.

Byte 2 through byte 7 are the data bytes.

Raw Command Response Format:

Byte Number	Description
0	0Dh: StrobeWriteCmd
1	<not used>
2	<not used>
3	<not used>
4	<not used>
5	<not used>
6	<not used>
7	<not used>

Raw Command Response Format Details:

Byte 0 contains the command. Byte 1 through byte 7 are unused.

Raw Command Example Usage:

Control this command’s port for the written byte, polarity and strobe line by using the StrobeWriteCmd or StrobeReadCmd. This command will then use the same selected port, polarity, and strobe line to write up to 6 bytes.
