SRC TCP/IP Stack

A pseudo TCP/IP stack for the SRC Telemetry System.

Usage

#include "src/src_tcp.h"

uint16_t count = 0; // Counter for the number of packets sent and received

int main()
{
        char data[] = "Hello World!"; // Data to send
        SolarTcpPacket *packet = createPacket(
            sizeof(data), data,
            DATA); // Create a packet with the data length, data, and type
        SolarTcpPacketHeader *header = createPacketHeader(
            SERVER); // Create a packet header with the type
        SolarTcp *solarTcp = createSolarTcp(
            header,
            packet); // Create a SolarTcp object with the header and packet
        char *rawSolarData = SolarTcpRaw(
            solarTcp); // Get the raw data from the SolarTcp object to send over the network
        std::cout << "Solar TCP Packet Header" << std::endl;
        std::cout << "Timestamp: " << solarTcp->header->timestamp << std::endl;
        std::cout << "Sequence: " << solarTcp->header->sequence << std::endl;
        std::cout << "Sender: " << solarTcp->header->sender << std::endl;
        std::cout << "Receiver: " << solarTcp->header->receiver << std::endl;
        << std::endl;
        std::cout << "Solar TCP Packet" << std::endl;
        std::cout << "Type: " << solarTcp->packet->type << std::endl;
        std::cout << "Length: " << solarTcp->packet->length << std::endl;
        std::cout << "Data: " << solarTcp->packet->data << std::endl;
        std::cout << "CRC: " << std::hex << solarTcp->packet->crc << std::dec
              << std::endl;
        std::cout << "Raw: " << rawSolarData << std::endl;
        std::cout << "Raw Length: " << strlen(rawSolarData) << std::endl;
        std::cout << std::endl;
        free(solarTcp->packet); // packet is allocated using malloc, use free
        delete solarTcp->header; // header is allocated using new, use delete
        return 0;
}
