Scott Shawcroft	6afb8dadbc	Change SPI and I2C in the same way.	3 years ago
hathach	894cad2e17	upgrade nrfx API to v2	3 years ago
Scott Shawcroft	6797ec6ed3	Add support for grayscale displays that are < 8 bit depth. ... This also improves Palette so it stores the original RGB888 colors. Lastly, it adds I2CDisplay as a display bus to talk over I2C. Particularly useful for the SSD1306. Fixes #1828. Fixes #1956	4 years ago

Radomir Dopieralski	8323721232	Stop hard-coding SPI frequency in FourWire ... Instead remember and use the frequency, polarity and phase that was set when the bus was first created.	4 years ago
Scott Shawcroft	9d91111b1b	Move atmel-samd to tinyusb and support nRF flash. ... This started while adding USB MIDI support (and descriptor support is in this change.) When seeing that I'd have to implement the MIDI class logic twice, once for atmel-samd and once for nrf, I decided to refactor the USB stack so its shared across ports. This has led to a number of changes that remove items from the ports folder and move them into supervisor. Furthermore, we had external SPI flash support for nrf pending so I factored out the connection between the usb stack and the flash API as well. This PR also includes the QSPI support for nRF.	4 years ago
