Initial implementation of mouse bot detection
7 years ago
fa00fd95dd
HID BotDetect functionality debugged and working:
...
- Implement advanced LED flash support
- Tweak HAL_SPI_TransmitReceive to tolerate a longer SysTick interrupt
- Tune KEYBOARD_BOTDETECT parameters
- L-shift and R-shift are now high-speed alphanumeric keys

- Refactor #ifdef names
- #ifdef out more HID code

Fix for occasional freakouts on mass storage writes.
...
Upstream's edge-detect interrupt that starts SPI transmission was not
firing. Sometimes. On some boards only. The cause was Downstream not
allowing enough time between edges for Upstream to catch the signal.
Also misc code tidyups.

Startup LED flash is now asynchronous.
...
Not only a faster startup process, but also catches some HID devices
that only work if initialised within 500ms of powerup.

Fix for occasional problem when attaching mouse after powerup.
...
It turned out we were getting a "device disconnected" interrupt while
waiting for the port to enable following reset. Simply ignoring the
disconnect interrupt allows everything to work! WTF...

Fix for occasional timeout on writes...
...
...Downstream was not always changing state correctly after closely
spaced interrupts.
Also improve flash-write-lockout function to avoid dependency on
optimisation level.

More work on enumerating cheap POS mice, arrrrgh.
...
Added timeout checks and retry functionality to control transaction
state machine. But some times the device just won't talk, so we flash
the fault LED slowly to give the user some clue about what happened.

Fixed enumeration issues with low-speed devices:
...
- Unexpected second port-connected interrupt on cold boot with low-speed
device connected.
- Retry on failure to get device descriptor. (We still fail after three
attempts, but that is better than failing after the first one!)
Also changed eclipse project to use external builder.

Changed Upstream and Downstream SPI transfers back to DMA. DMA works
...
correctly now, either because SPI is in 16-bit mode, or because I found
all the other bugs!
Doubled SPI baudrate to 10.5Mbps. Transfer speed now limited (again) by
Downstream's lack of FIFO buffering in the USB host controller.
Also disabled DMA transaction half-complete interrupt in
stm32f4xx_hal_dma.c, as it wasn't doing anything useful.

Completed moving Upstream to interrupt-based SPI.
...
Although I am not entirely convinced this is necessary, as the SPI data
stall issue only appeared with optimisation off (-O0). Perhaps re-visit
this if Upstream needs more free CPU time later...
