Supports speeds up to 500k baud, polarity=0/1, phase=0/1, and using any
pins.  Only supports MSB output at the moment.

Damien George 3fbbbecec9 esp8266: Put more code in iROM section.
Also explicitly name the py/*.o files in the linker file, to enable easy
testing of putting certain ones in iRAM.

Damien George f09f8097d5 esp8266: Put more code in irom0 section, to get it building again. 2015-10-20 22:59:31 +01:00
Josef Gajdusek 7d8edeff4e esp8266: Update to SDK version 1.1.0 (MIT-licensed).
1. Updated linker script, now user app appears to contain exception vector
table and oesn't work (faults) without it.
2. Commened out support for GPIO pulldown, which was removed in this SDK
version without clear explanation, but apparently because it was released
without proper validation, and now turns out it doesn't work as expected,
or there's a different function there.

Damien George 304a96d7d6 esp8266: Put more literal and text obj data in irom0_0_seg.
With newer versions of esp_iot_sdk the iram1_0_seg started to overflow.
Now it doesn't.

Addresses issue #1254.

Josef Gajdusek b47931978f esp8266: Update the linker script

value was taken from NodeMCU linker script.

Damien George e636279fe0 esp8266: Move more rodata to irom section.
rodata can only go in iram/irom if it's accessed only using word loads
(ie no byte or half-word access).

Damien George fbea810043 esp8266: Change bignum from mpz to longlong; move some rodata to iram.
Some rodata items can go in iram/irom segment, but not others.  With
this patch ESP now has 24256 bytes of heap ram.  It passes 228 out of
248 tests from tests/basics directory.
