baud rate SDCard HxC Floppy emulator

Post by Music4Lynx »

What is the baud rate used in the pin "floppy data"?
for .adf files, emulating Amiga500.

Sorry for my english...

Thanks!

Because I love electronics and programming and I like to meet and learn how things work.
How do you set the baudrate of the pic to the pin "floppy_data"?
What parameters do you use?
I would like to understand and comprehend the communication between the Amiga500 and your PIC.
Is the image inserted in the SD, is encoded in MFM?
If so, the bitrate of the PIN "floppy_data" must be double (500kbits per second)?

Sorry for my english and thanks very much!

and for finish :-)

When is the instantly for send data PIC to the Amiga500?
Are there any signals that indicate when you send data?
How do you know when you have finished producing "stepings?
How do you know when you have finished "the seek function" the Amiga500 to know the number of "steps" (your floppy_step signal in your schematics circuits) that must be produced?

Sorry for my english, is very poor... and thanks you very much.
