The defualt in NuttX is OSPEED of 50Mhz. This is realy a slew
rate control. At the default high slew rate the overshoot was
.7 Volts. On a ICM20649 this was causing the device to output
garbage. All 0s
N.B. A passive scope or Logic analyser's probes load will mask
the failure. Useed a FET probe to verify the issue.
* Add basic GPIO test app for R/W on pins from nuttx shell
* Add gpio command to fmu-v3 and fmu-v4
* Sanitize gpio commands by pin configs, --force to override
- skip avionics rail voltage check when USB connected
- skip forced reboot on USB disconnect if circuit breaker set
- avionics voltage preflight check don't silently fail if system_power unavailble
- explicitly set supply check circuit breaker (CBRK_SUPPLY_CHK)
- always check with state machine before reboot/shutdown
- respect BOARD_HAS_POWER_CONTROL (shutdown from command, low battery, power button)
- px4_shutdown_request add optional delay and always execute from HPWORK
- px4_shutdown_request split out px4_reboot_request
- increase stack sizes to run cleanly under stackcheck
- this is likely overkill for most boards, but using stackcheck to set our minimum ensures we have a very safe margin on regular builds and it's something we can currently afford
- remove holybro_durandal-v1_stackcheck from test rack (there's only one unit)
- this doesn't currently change anything, but gets us ready to start
experimenting with using the small amount of instruction tightly memory
on STM32F7
- the .ramfuncs section works with NuttX CONFIG_ARCH_RAMFUNCS
This moves the handling of the BAT%d_SOURCE param inside of the battery
library. Users of the library now pass the source instead of the flag
whether to publish. The battery library then checks if the source is
selected using the param and publishes accordingly.
Since we removed the strange system_source flag, we now need to look at
all batteries in commander.
For current estimation - I think - it makes sense to sum them up.
