Insure a 0.0 voltage initial condition on VDD_3V3_SENSORS
By starting the GPIO_VDD_3V3_SENSORS_EN, low and deferring
the GPIO init of the slave selects and drdy signals until
board_app_initialize. We get ~ 180 ms of power off time
with 0.00 voltage applied to the sensors.
Given the original poster's comment that "It happens very consistently for us." I suspect the motor spin observed in https://github.com/PX4/Firmware/issues/7457 is not caused by the original issue of slow decay on the PWM pins at reset, but the post reset pulse of 3.1 Ms arriving in a window that the ESC considers it valid.
The results from testing, indicated that the if the PWM pins were clamped low for > 300 Ms, prior to reset the motors did not spin. This would delay the the post reset pulse of 3.1 Ms out by > 300 Ms.
This change delays the reset and therefore the pulse by at least 400 Ms.
problem: previously when connecting power to Power 1, commander refused
to arm (no power source error), and when connecting to Power 2, arming
works, but power consumption was not measured (& shown in QGC).
Swapping Brick1 with Brick2 makes sure both works when connecting to
power 1.
Ideally we will have support for both power sources (including fail-over)
When the CCER is cleared the IO pin tends to float. The FMUV4
HW has no TXS0108 and if cut off while high will decay.
By adding the pull down the pins will seek the low state faster.
13.8 us from off to decabe below threshold.
* FMUv4pro : allow power monitoring for hipower rail
* FMUv4pro : init temperare calibration EEPROM CS
* FMUv4pro : workaround for safety switch
* FMUv4pro : remove useless and conflicting defines
* FMUv4pro : disable internal pull-up for OC sensing
/FAULT won't achieve VinputLow with internal pull-up resistor so it must
be turned off for both /VDD_5V_PERIPH_OC and /VDD_5V_HIPOWER_OC.
Replaced by external pull-up.
* FMUv4pro : correct safety switch handling
RC02 has a hardware pull-down on this signal
* Revert "FMUv4pro : workaround for safety switch"
This reverts commit 9528ae29b68700fa7c6604c1ac2756c7dac2819c.
- There's no I2C2, so remove it
- Fix alignments everywhere in board_config.h
- Clarify STM32 ADC (not available) and the ADC on the FGPA
- Fix format on some comments
FMUv4 PRO HW does not have a controlable V3.3 on the connector
it therefore can not support the SPEKTUM binding.
This PR removes the Power switch controls or binding control
interfaces from the board config
Removed the legacy FMUv4 define that was activating a nonexistent
pull up and on some HW driving the PPM_IN aka RC_IN aka SPEKTRUM_RX
to VDD.
Also detailed the connections of this pins for the board.
The simplest connection is RC_IN to a timer capture pin
and a UART.
In this case the UART_RX pin and just be left as is.
While the pin can be configured as the PPM_IN (Timer capture)
or as SPEKTRUM_RX_AS_GPIO_OUTPUT to use it as and GPIO to
facilitate binding.
Renamed the macros and defines to be more explicit as to what
Is being done and the sense of the parameters
