Retrieving the Appropriate Bits From Data
Posted on 2003-11-25
I have a problem. I will be using VB6 to code an application to retrieve the appropriate bits from the data. This application will communicate with Device 1, whilst Device 2 can only communicate with Device 1. The application in the PC will always poll Device 1 for data, whilst Device 1 will poll Device 2 for data. The data is stored in the buffer of the device. The protocol is as follows:-
01 01 01 01 4fH n 12bytes
When <Level> = 2, this show that PC is polling for Device 2 data. Device 1 will start to poll data in Device 2 buffer. The data will then transfer from Device 2 buffer to Device 1 buffer. how can I code in VB to send this command to poll for device 2. After getting the data, how can i abstract the last 6 bytes from the data and drop the first 6 bytes?
