Andy Green	e3743d47b4	lws_spi: Add esp32 DMA support ... This provides an alternative esp32-specific SPI driver with ops that can be swapped in place of the gpio bitbang one. The pinmux info and lws gpio driver and other data in the spi bitbang struct are used as-is by the DMA one. New ops are provided which are able to allocate and free DMA-able memory so the device drivers can prepare directly usable buffers. Bounce through to DMA-able buffers is also transparently supported.	2022-03-25 08:18:30 +00:00
Andy Green	63c1e8ba00	esp32-wrover-kit ... Add lws_display and minimal example support for esp32-wrover to match wsp32-heltec-wb32 Since no usable buttons that don't affect something else on wrover kit, assumes a button to 0V on GPIO14.	2020-06-30 19:35:41 +01:00
