First of all, to clarify my goal: There exist two programs written in C in our laboratory. I am working on a Proxy Server (bidirectional) for them (which will also mainpulate the data). And I want to write that proxy server in Python. It is important to know that I know close to nothing about these two programs, I only know the definition file of the packets.
Now: assuming a packet definition in one of the C++ programs reads like this:
unsigned char Packet[0x32]; // Packet[Length]
int z=0;
Packet[0]=0x00; // Spare
Packet[1]=0x32; // Length
Packet[2]=0x01; // Source
Packet[3]=0x02; // Destination
Packet[4]=0x01; // ID
Packet[5]=0x00; // Spare
for(z=0;z<=24;z+=8)
{
Packet[9-z/8]=((int)(720000+armcontrolpacket->dof0_rot*1000)/(int)pow((double)2,(double)z));
Packet[13-z/8]=((int)(720000+armcontrolpacket->dof0_speed*1000)/(int)pow((double)2,(double)z));
Packet[17-z/8]=((int)(720000+armcontrolpacket->dof1_rot*1000)/(int)pow((double)2,(double)z));
Packet[21-z/8]=((int)(720000+armcontrolpacket->dof1_speed*1000)/(int)pow((double)2,(double)z));
Packet[25-z/8]=((int)(720000+armcontrolpacket->dof2_rot*1000)/(int)pow((double)2,(double)z));
Packet[29-z/8]=((int)(720000+armcontrolpacket->dof2_speed*1000)/(int)pow((double)2,(double)z));
Packet[33-z/8]=((int)(720000+armcontrolpacket->dof3_rot*1000)/(int)pow((double)2,(double)z));
Packet[37-z/8]=((int)(720000+armcontrolpacket->dof3_speed*1000)/(int)pow((double)2,(double)z));
Packet[41-z/8]=((int)(720000+armcontrolpacket->dof4_rot*1000)/(int)pow((double)2,(double)z));
Packet[45-z/8]=((int)(720000+armcontrolpacket->dof4_speed*1000)/(int)pow((double)2,(double)z));
Packet[49-z/8]=((int)armcontrolpacket->timestamp/(int)pow(2.0,(double)z));
}
if(SendPacket(sock,(char*)&Packet,sizeof(Packet)))
return 1;
return 0;
What would be the easiest way to receive that data, convert it into a readable python format, manipulate them and send them forward to the receiver?
