| 2019-11-18 | Supervisor: move most of systick to the supervisor | Jeff Epler | |
| This code is shared by most parts, except where not all the #ifdefs inside the tick function were present in all ports. This mostly would have broken gamepad tick support on non-samd ports. The "ms32" and "ms64" variants of the tick functions are introduced because there is no 64-bit atomic read. Disabling interrupts avoids a low probability bug where milliseconds could be off by ~49.5 days once every ~49.5 days (2^32 ms). Avoiding disabling interrupts when only the low 32 bits are needed is a minor optimization. Testing performed: on metro m4 express, USB still works and time.monotonic_ns() still counts up | |||
| 2018-11-08 | Move atmel-samd to tinyusb and support nRF flash. | Scott Shawcroft | |
| 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. | |||
