Support for receiver configuration (PPM, PWM and DSM)
There are still problems with Flexi port (not sure if related to a problem with my board) and Uart/SBUS that has the input always inverted.
CPU was being hammered with FIFO empty IRQs if we queued data but
the host wasn't actively draining the FIFO.
This was entirely unexpected so this hack should probably be
removed once we can figure out why this was happening.
This is almost certainly hiding some other issue.
Make sure we don't clobber our endpoint configuration by
double configuring an Rx or Tx buffer against it. Wait for
the completion of the previous operation before allowing
endpoint configuration again.
Upper (COM) layer was calling down into the HID layer before
the HID interface had been enabled. This was leading to
interacting with the endpoint Rx and Tx FIFOs prior to init.
The FIFO config was then being clobbered when we the USB IF
was eventually enabled.
Error flags being set were causing flash erase operations to
fail. Not sure why these flags were set though so this might
be hiding some other problem.
HID driver was incorrectly giving back the HID interface
descriptor when asked for the HID descriptor. This should
let OP boards interact better with generic HID layer drivers
and also gives us nicer output in lsusb once the HID descriptor
is read.
These new build targets will construct a flash image that
includes both a bootloader as well as a firmware image all
in one. Examples:
make ef_coptercontrol
make ef_revolution
This also adds support for a new target for writing this EF
image to boards that support a DFU interface (only F4-based
boards). This can be done by running:
make dfuutil_install
# Boot board with SBL asserted to activate STM32 DFU ROM
# Attach USB cable
make ef_revolution_dfu
Bootloader images are also now padded out to occupy the full
BL flash region.
transaction doesn't start at the beginning again. Something is still not quite
right because first few bytes aren't getting across. Need logic analyzer.
transactions should already be completed. Also reset the callback so in the
case of noise on the IRQ line it will not keep firing interrupts.
I suspect we should probably disable interrupts in this handler to prevent
refiring.
The PIOS_MASTER_CLOCK has been removed in favor of
PIOS_SYSCLK (the master clock value,168000000 for revolution)
PIOS_PERIPHERAL_APB1_CLOCK and
PIOS_PERIPHERAL_APB2_CLOCK
Look at STM32F4xx_Revolution.h for the list of timer/peripheral and APB them belongs.
