Command Structure.
Viewing data from the Multiflow;
All data is sent and received as ASCII HEX pairs, the maths used in PIC Hex format, 2 example routines are
included to convert this data into PC or ASCII strings. The PIC Hex format is always 4 bytes and represents a
32-bit floating-point number system. To read data use the following format.
Description ID View Hub/Slot Reg/Mem Slot Address No.Bytes CR
String a V H R 00A0 04 CR
Hex 61 56 48 52 00A0 04 0D
ASCII Hex 36 31 35 36 34 38 35 32 30 30 41 30 30 34 0D
Notes: Reg/Memory allows the user to view live data within the Processors own working registers or the Flash
memory address space that is used to store constant and curve data. The Hub is the main processor (the card
connected to the serial link), whilst the SLOTs need to be addressed as follows.
