+/*
+ * PSn00bSDK controller polling example
+ * (C) 2021 spicyjpeg - MPL licensed
+ *
+ * This example shows how to poll controllers at high speeds (250 Hz) by using
+ * timer interrupts and communicating with devices on the SPI controller bus
+ * manually rather than relying on the BIOS pad driver, which is limited to
+ * 50/60 Hz and does not support custom commands. The example also demonstrates
+ * using configuration mode commands to force DualShock pads into analog mode
+ * and enable button pressure sensing on DualShock 2 (PS2) controllers.
+ *
+ * See spi.c for details on how the low-level SPI communication driver works.
+ * The DualShock handshaking logic is implemented here (see poll_cb() and
+ * dualshock_init_cb()). There is no support for memory cards in this example,
+ * but the code in spi.c can be used to read/write sectors on a memory card and
+ * combined with a higher-level filesystem driver for full support.
+ *
+ * IMPORTANT: this example hasn't yet been tested on real hardware and/or with
+ * unofficial controllers, which might behave differently at higher poll rates.
+ * Also keep in mind that many emulators emulate controllers and memory cards
+ * inaccurately. It is thus recommended to test controller I/O code extensively
+ * and handle as many edge cases as possible (e.g. partial but valid responses,
+ * zerofilled responses, slow replies) for maximum compatibility.

+ * PSn00bSDK controller polling example (SPI driver)
+ * (C) 2021 spicyjpeg - MPL licensed
+ *
+ * This is a fairly complete timer driven, asynchronous high-speed SPI driver,
+ * with support for sending custom commands (including memory card access), in
+ * about 200 lines of code. Feel free to copypaste and adapt it.
+ *
+ * The way this works is by maintaining a queue of requests to send, each with
+ * its own payload and callback. Timer 2 is configured to trigger an IRQ at
+ * regular intervals. On each tick, the next request in the queue (or a poll
+ * command if no request is pending) is prepared and the first byte is
+ * sent; if the controller asks for more data by pulling /ACK low, the next
+ * byte is sent and the received byte is placed into a buffer. This goes on
+ * until the last byte is exchanged and the controller stops asserting /ACK.
+ *
+ * On the next tick, the response buffer is passed to the request's callback
+ * and reset, and the next request in the queue is sent. This blindly assumes
+ * it only takes one tick for a request/response to be sent, which is the case
+ * for controllers' very small packets but not for memory cards. It is
+ * advisable to call spi_set_poll_rate() to temporarily reduce poll rate while
+ * accessing memory cards.
+ *
+ * Note that this driver completely takes over the SPI bus, so you won't be
+ * able to use any BIOS functions that rely on SPI access (i.e. pad and memory
+ * card APIs) alongside it.
