Patch spi

[zaphoxx]

updated the spi sniffer capability

• added handling of WAIT states
• added handling of #bytes transmitted (instead of reading only 1byte from MISO)
• added gpios to handle dipswitch input for sniffer mode selection
• added some blinkyblink on the onboard led when sniffing starts and when key has been found
• update the pio spi file to flush the isr when select line is low on raising clock edge to avoid bit offsets
• moved the countdown (5 sec) after the logo shows and made the countdown (sleep) visual
• dipswitch position 0 --> spi bios sniffing; dipswitch position 1 --> lpc sniffing
• added the gerberfile(s) from my pcb for reference
• vmk header check is updated

i think thats it. let me know if you have any questions or suggestions.

I finally got an SPI machine - so I will try to test this :)

Thanks for creating this upgrade project 👍
Would it be possible to share your KiCad files from the modified SPI sniffer aswell?

The reason why I ask this is because I was able to export a CPL (component placement list) file from the original KiCad files that were provided by stacksmashing. I couldn't find a way to extract such a CPL file only from the gerber files that you did provide on your github.

Together with the gerber files, the CPL file and a little BOM list I was able to use the soldering service from the company pcb way to create the original pico TPM sniffer. Maybe it's possible to create a similar project with yours aswell?
