Factor out "sd_card_{1bit,4bit,spi}" resources. 2019-10-03T05:46:09+00:00 whitequark whitequark@whitequark.org 2019-10-03T05:42:59+00:00 urn:sha1:b033d53db305eb3f0aef336568cd69f8e8c536e1 dev.display: factor out from dev.user.

There are no provisions in this resource itself for multiplexing the display. It is expected that on boards with multiplexed displays, an additional resource "display_7seg_ctrl" will be provided, and it would have either an n-bit signal "sel" (binary encoded) or an n-bit signal "en" (one-hot encoded). (This may be revisited in the future.) Fixes #17. dev.user: fix typo. 2019-09-23T10:11:39+00:00 whitequark whitequark@whitequark.org 2019-09-23T10:11:39+00:00 urn:sha1:b8b2bbaff34c905f2b1094a74b6865961feb2290 [breaking-change] Factor out "led", "button" and "switch" resources. 2019-09-23T08:07:37+00:00 whitequark whitequark@whitequark.org 2019-09-23T08:07:37+00:00 urn:sha1:dd87f472af92a73d18b3ef363603f20bd071306e These resources were renamed as: * user_led → led * user_btn → button * user_sw → switch Fixes #13.
