Program Screenshot

Updated 2006-04-17: 1.2.62
Tons of assorted fixes.
UDP actually works now.
Displays all ASCII characters now.
Focus auto goes to the send textbox upon connect.
Hitting ENTER in the address/port textboxes will initiate connect. Doing so in the send textbox will send the data out.
Right click the Listen button for Auto-listen. It will continue to listen on the specified port if the remote connection closes.
Right click the Connect button to Bind to a specific local IP address. Type the IP to bind to in the Address text box first.
Right click the Connect button to use a basic Sniffer. It acts as a passive proxy and displays the data going in/out.
Double-click the data window to clear its contents.
Small resizing function updates. Form elements align better across different OS styles/themes.

Updated 2003-10-16: 1.2.38
Fixed some bugs, displays in color (sent data in blue), resizes better now

AVRs are generally classified into four broad groups:

  • tinyAVR — the ATtiny series
    • 1–8 kB program memory
    • 8–32-pin package
    • Limited peripheral set
  • megaAVR — the ATmega series
    • 4–256 kB program memory
    • 28–100-pin package
    • Extended instruction set (Multiply instructions and instructions for handling larger program memories)
    • Extensive peripheral set
  • XMEGA — the ATxmega series
    • 16–384 kB program memory
    • 44–64–100-pin package (A4, A3, A1)
    • Extended performance features, such as DMA, “Event System”, and cryptography support.
    • Extensive peripheral set with DACs
  • Application specific AVR
    • megaAVRs with special features not found on the other members of the AVR family, such as LCD controller, USB controller, advanced PWM, CAN etc.
    • FPSLIC (Field Programmable System Level Integrated Circuit), an AVR core on-die with an FPGA. The FPSLIC uses SRAM for the AVR program code, unlike all other AVRs. Partly due to the relative speed difference between SRAM and flash, the AVR core in the FPSLIC can run at up to 50MHz.
