Uthernet II Snooper CDA

This is a Classic Desk Accessory to peek and poke at the Uthernet II/Wiznet w5100 registers.

Slot 3 is assumed.

Built with the SNASM assembler and snlink, sorry.

Keys:

• C - Common registers
• 0 - Socket 0
• 1 - Socket 1
• 2 - Socket 2
• 3 - Socket 3
• R - Receive buffer
• T - Transmit buffer
• Left arrow, right arrow - switch between pages
• Up arrow, down arrow - scroll through memory (RX/TX only)
• : - write memory.
• Esc - quit
• Q - quit

Writing memory:

Format is address : xx [xx ...] where xx is a hexadecimal byte and address is 8-bit or 16-bit hexadecimal. spaces are optional.

For the socket registers, the page high-byte ($00, $04, $05, etc) is pre-loaded so an 8-bit address will work as expected. The display will be reloaded after a write but keep in mind some registers are not visibly changed until a command is entered (eg, tx write doesn't update until a send command).

Be careful writing the MR register ($00) :-)
