Actually it is not an issue but a comment to support ATmega.

Tested: ATmega328p & Arduino Nano 3.0
Should also work: ATmega8/48/88/168/328
Or Arduino UNO, Nano, Pro Mini

Revise the file "sdlocker-tiny.cpp" line 121 - 124 & 135

#define MOSI_BIT 3 //Arduino D11
#define MISO_BIT 4 //Arduino D12
#define SCK_BIT 5 //Arduino D13
#define CS_BIT 2 //Arduino D10

#define LEDSW_BIT 1 //Arduino D9

Copy whole code (File: sdlocker-tiny.cpp) to Arduino IDE, revise the lines, select the board, and upload. Cheers.

I would like to know whether you'd consider selling a unit to me? See my comment here: https://hackaday.com/2014/01/18/the-tiniest-sd-card-locker/#comment-5030677

You can contact me by mailing to reuben [dot] register [at] icloud [dot] com

Thanks!

Hi, I'm struggling to understand the wiring "diagram" in the .cpp file and was hoping that a simple diagram (even in something like tinkercad) would be able to be added to the readme. Maybe @CRImier (judging from #3 ) could chime in on this?

Many thanks,
Jake

Could you give a complete list of parts for this project? Looks really great.

I forked the repo (to my tz1) and added USI support. The docs are at best confusing, at worst wrong, but I get the high speed.

NOTE MOSI and MISO are REVERSED!!! - I needed to swap the pins.

I'm also not using the interrupts, but doing a series of writes to the register to do the clocking - 1 cycle each. There are other optimizations, but this is the main one.

I've done I2C master using the USI, and always wanted to try to get the SPI working.

Thanks for the port.
