Raspberry Pico Maple Bus TX/RX implemetation #1

ismell · 2021-03-14T17:37:51Z

This PR in the start of Maple Bus support on the Raspberry Pico.

TODO:

Add DMA helpers to send/receive frames.
Figure out if using an event loop with WFI or use IRQs. The latter sounds complicated.
Write code to actually emulate a controller.
Write a USB driver to support the Xbox 360 Wireless adapter.
Wire all this together.
Write documentation on how to wire up the Pico to the Dreamcast
Evaluate writing all this in Rust?

See http://mc.pp.se/dc/maplewire.html for the wire protocol and http://mc.pp.se/dc/maplebus.html for the data format.

Implement functions to allow for DMA usage in audio driver.

* Fix path + typo in README.md * Remove incorrect path change * Remove typo

…one has already installed one (#375)

…able interrupts around division rather than using co-operative guards to protect nested use (i.e. within IRQ/exception). Use of this flag can simplify porting of RTOSes but with a different performance profile (#372)

…B_FOO=1, and remove bespoke definitions which were all undocumented anyway (#374)

…andler due to in use mutex. build was non deterministic due to missing link wrapping of getchar (#364)

* Change some cmake output to DEBUG level Make SDK build more consistent with other libraries (use an INTERFACE marker library for inclusion tests) Add PICO_SDK_PRE_LIST_FILES, PICO_SDK_POST_LIST_FILES build vars * fix typo * remove leftover debugging message

USBTMC: remove reference to visa DLL (which only was for windows, and…

- Add recursive_mutex - Make all locking primitives and sleep use common overridable wait/notify support to allow RTOS implementations to replace WFE/SEV with something more appropriate - Add busy_wait_ms

Update API description.

Added new RTOS names to the name string array in print_greeting() in the host example program. The program seemed to hang when a new RTOS was indexed in CFG_TUSB_OS.

Remove reference to the deprecated "num" and "in" members of struct hw_endpoint which still exist in an assert statement and break DEBUG builds.

Update main.c

Update hcd_rp2040.c

Fix code where HID keyboard was being stuffed into the HID mouse buffer.

Merging in my tinyusb fixes.

This is a common struct that describes all USB descriptors. Signed-off-by: Raul E Rangel <[email protected]>

We need more logs!

This will print out all the end points and interfaces supported by the device.

Useful when debugging why a driver doesn't match

This driver is only partially complete. It enumerates the device and prints out the status of the controller. The interface to publish the events stil needs to be defined. Signed-off-by: Raul E Rangel <[email protected]>

This lays the foundation for having host/peripherals running in the same program loop.

We should use something with data.

Let's try and have some clean code.

This doesn't support waking yet, but it's a start. Once we implement maplebus_rx, we can loop back packets larger than 6 dwords. Signed-off-by: Raul E Rangel <[email protected]>

This will make sure we actually loop back

This way we don't get confused.

This is an async version. We should now be able to send and receive larger packets.

We are now async!!
