cf34beebb0 Remove extra call to switchctrl_set and global switchctrl variable. 
This call is not required since the GPIOs are already configured in
rf_path_pin_setup(). The global switchctrl is not used anywhere else.

eec6963759 Initialise RF path GPIOs to safe settings. 
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.

Detect hardware platform at run-time.

9329c5e44e Detect hardware platform at run-time. 
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.

2104291594 firmware: use consistent clock source 
CLKOUT now switches to the active clock source whenever the internal
clocks change source. It previously did so only when (re)enabled.

a943610cd4 Simpify TX loop in the same way as RX loop. 2022-07-25 10:44:15 +01:00
Martin Ling
0175c2e84e Simplify rx_mode loop and prevent it stalling. 
On rad1o, the UI update could block this loop from running for long
enough that it could stall in a state where neither of the conditions
was met.

Fix this by removing the 'phase' variable, in favour of a counter
tracking the number of bytes that have been scheduled for USB transfer.
Whenever there are enough bytes to schedule the next transfer, do so.

Meanwhile, the M0 count is prevented from wrapping around and clobbering
data not yet sent, because the M0 code monitors the m4_count variable
which is updated as each transfer completes.

273e6a1217 Add an accurate delay loop. 
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."
