Piotr Esden-Tempski 20ef4efd8b Added the FTDI cable pinout for reference. 2018-08-18 15:29:11 -07:00
Piotr Esden-Tempski f4ff8f7630 Improved JEDEC ID read function. 
The function now checks how long the extended JEDEC ID field is for the
particular FLASH chip and only reads the amount provided by the chip.
 2018-08-18 15:26:37 -07:00
Piotr Esden-Tempski 3ba1acf31b Replaced some more magic numbers with FLASH command IDs. 
I missed those the first time around.
 2018-08-18 14:46:12 -07:00
Piotr Esden-Tempski ee7eae0be8 Added easier to read chip_select/reset functions. 
Just calling a gpio function with two numbers was not very self
explanatory. The functions now refer to the actual indended action, chip
(de)select for flash, reset and chip (de)select for sram. Reading the
code and understanding what steps are taken should be easier now.
 2018-08-18 14:41:42 -07:00
Piotr Esden-Tempski 96b1a90f28 Added more code comments. 
Main point was to group the code into three logical segments:
* MPSSE/FTDI defines and functions
* FLASH defines and functions
* iceprog implementation core

While I was at it I also added a few comments for stuff that was not
immediately obvious what it does.

Elms 61aa5c5094 icebox_hlc2asc: fix _lut_ keyword parsing 
'self.lut_bits is None' was always false. The _lut_ keyword is used by asc2hlc, so when converting asc->hlc->asc the lut_bits were always all zeros.

Tim 'mithro' Ansell ef618927ca icebox_vlog: Save error message to file and print it. 
Previously if you were doing;

`icebox_vlog example.asc > example_bit.v` you would just get;

```
Traceback (most recent call last):
  File "icebox_vlog.py", line 947, in <module>
    assert False
AssertionError
```

Now you get;
```
Traceback (most recent call last):
  File "icebox_vlog.py", line 948, in <module>
    assert False, "\n  ".join(emsg)
AssertionError: Single-driver-check failed for 2 nets:

Tim 'mithro' Ansell 82f2f3d278 HLC: Use '~>' instead of '<->' for routing switches. 
As mentioned in ca6b2d9ebd, the 'routing'
switches are not actually bidirectional. This makes the '<->' specifier
very misleading.

Instead use '~>' to differentiate it from the 'buffer' switches.
