when a peripheral is made available via BRD_ALT_CONFIG we need to
remap the existing ioline_t in the UART and I2C drivers to use the new
pin.
This fixes an issue with half-duplex, inverted, swapped UART pins for
protocols like FPort and FPort2
when both I2C4 and SPI4 are active on a H743 I found that some BDMA
completion interrupts were lost, which resulted in SPI transfer
timeouts. Close inspection of the ChibiOS BDMA, I2Cv3 and SPIv3
drivers did not reveal any issues, but I found that the issue only
happened when the first 4 BDMA streams were used. This change splits
the 4 streams across the first and 2nd half of the BDMA controller,
and that fixes the problem.
This works as there are only 2 peripherals (I2C4 and SPI6) that want
to use BDMA with our current setup. If we ever wish to enable ADC3
(which also uses BDMA) we will need to revisit this issue
implements an FFT engine based on the betaflight feature using ARM hardware accelerated CMSIS library
make the FFT feature optional
add dynamic gyro windows
add quinns and candans estimators and record in DSP state
disable DSP for boards with limited flash
calculate power spectrum rather than amplitude
start/analyse version of analysis to support threading
allocate memory in a specific region
constrain window size by CPU class
control inclusion of DSP based on board size
If a defaults.parm file was present in the hwdef, waf ignored the --default-parameters=xyz.parm command line argument. This will allow it to use that command line argument specified file.
