Previously these calls were leaving the amplifiers on, since the
control settings passed were missing SWITCHCTRL_NO_TX_AMP_PWR and
SWITCHCTRL_NO_RX_AMP_PWR. Use the predefined SWITCHCTRL_SAFE here.
Also move these calls before setting the GPIO pins to output mode,
to avoid driving them to the wrong states briefly first.
Firmware now detects the hardware it is running on at startup and
refuses to run if it is compiled for the wrong platform. The board ID
returned by firmware to the host is now derived from run-time detection
rather than a compile-time value. A separate method to retrieve
compile-time supported platform is added.
On HackRF One, pin straps are checked to determine hardware revision.
This is informational to aid troubleshooting and does not affect any
function.
The existing 'delay' function is not calibrated to any specific measure
of time. Add a new function using a loop with a known cycle count, to
produce delays of a given duration at a given CPU clock speed.
From USB 2.0, section 9.4.5:
"For endpoints using data toggle, regardless of whether an endpoint has
the Halt feature set, a ClearFeature(ENDPOINT_HALT) request always
results in the data toggle being reinitialized to DATA0."
These variables are already placed together; this commit just groups
them into a struct and declares this in a new header.
This commit should not result in any change to the firmware binary.
Only the names of symbols are changed.
When switching to frequency mode or modifying the frequency ranges,
ensure that the Opera Cake is switched to the correct port on the very
next tuning.
This uses `add_custom_command` to run a cmake script instead of using
`configure_file` directly, which allows for adding dependencies and
creates an ouput that can be depended on.
It also uses `add_custom_command` instead of `add_custom_target` to
create the M0 binary, since custom targets have no output file to depend
on.
Unfortunately, multiple targets cannot depend on the same generated file
or cmake tries to run the generation multiple times in parallel. So, the
.bin/.s generation is now duplicated for each target so they don't
conflict.
