Andrew Dennison 67e6614eb2 test_i2c: whitespace cleanups 2024-07-20 15:45:44 +10:00
Radek Pesina 643f3f9a93 test_i2c: add more commands 2024-07-20 15:45:44 +10:00
Andrew Dennison f99658200e soc/cores/i2c: rewrite state machine 
* Fix READ: was reading too many bits
* CLeaner transitions between states: ACK=>IDLE with scl=0. Other to IDLE with scl=1
* Now cleanly supports RESTART
* conceptual support for compound commands - not exposed yet
* fix tests: now appears to be I2C compliant
 2024-07-20 15:45:44 +10:00
Andrew Dennison 13811aeacb test_i2c: update to use improved _MockTristate 
* test now checks the actual i2c bus state, not the I2CMaster output
* refactor to eliminate some copy/paste
* tests now work again with this change: 'only change SDA when SCL is stable'
 2024-07-20 15:45:44 +10:00
Andrew Dennison b779933a5f test_i2c: improve and document _MockTristate* 
Added i_mock for simulated external device:
    * when _oe = 0 _i = _i_mock
    * when _oe = 1 _i = _o
 2024-07-20 15:45:44 +10:00
Andrew Dennison dce152b348 soc/cores/i2c: change SDA 1 or 2 cycles earlier 
* update 'only change SDA when SCL is stable' to max 1 sys_clk delay

Andrew Dennison c867d5647b soc/cores/i2c: only change SDA when SCL is stable 
Avoid changing SDA immediately in states WRITE0 and READ0 to guarantee SDA hold is > 0
