MIDIcar - Independent MIDI device for Atari XE

Introduction I would like to present new device for Atari XE series which can play/record MIDI files on Atari 8-bit computer. Idea was taken from SIO2MIDI (https://ataribits.weebly.com/midi.html) but I decided to use CART/ECI port for communication with MIDI devices because in case I may use SIO in...

Re: A2I2C - I2C bus for Atari

Hi, As you mentioned, the /RESET line is open drain and for normal work you need to pull-up it to Vcc thru resistor but I suppose your microcomputer system has this line pulled-up in other place. Are you sure that PCF8584 RESET pulls the line down? It's input pin, so probably PCF is damaged. I had i...

Re: A2I2C - I2C bus for Atari

I analysed my project again according to additional information regarding specific timing (AN96040 - added to first post) and now I'm pretty sure that the interrupt signal may disturb data communication between PCF8584 and microcomputer subsystem. I'll cut /INT line from existing PCB (especially tha...

Re: A2I2C - I2C bus for Atari

Hi, Generally it's look very good... (KiCAD)? Actually I see one issue... please clarify if I'm wrong. You are using the same CLK signal for 6502 and PCF? If yes, PCF will not be capable for so quick operations at all. Nice address decoder but in case you have many shadow registers :-). Did you conn...

Re: A2I2C - I2C bus for Atari

Hi, I'm using MADS assembler as you guessed. The asterisk (*) with equ directive means that code started from i2cbuf should be placed in memory just here. It's dynamically allocation for i2cbuf. Another words, * is a pointer for memory address in the code stream. In case you have: ... 215 6115 00 le...

Re: A2I2C - I2C bus for Atari

Hi, My prototype works fine with one condition.. touching I2C bus not so fast :-) So if you planning use full PCF8584 features consider to use external clock (e.g. 12MHz) for it. I'm used PHI2 clock - it was mistake. For more details see page: http://radio86rk.pbworks.com/w/page/134476563/rk86-2018-...
