Hi, I'm trying to get a 32 bits PIC controller to work with a ROACH. I'm establishing communication through a standard TCP connection and getting data from a socket opened between the PIC and the ROACH. About this I have two questions:
1.- What is the package size, also know as maximum segment size, that the ROACH/KATCP uses for transmission over the LAN port? I need to know this so I can work with the same segment size on both platforms and get proper data flow synchronization. 2.- Do you know where can I find more info about the way struct.pack works? I need to "unpack" the data coming in the string from the ROACH, but since I have no python libraries on the PIC I need to handle the unpacking myself. Looking directly at the data I seem to recognize some patterns (i.e. "/0" at the end of each integer per channel) but this patterns are not behaving the same through the whole string. Any hints will help. Best regards. -- Pablo Vasquez Ingeniero Eléctrico DAS Universidad de Chile (+562)29771119
