Merge pull request #88 from paltatech/current-sensor-fault-detection 
Detect current sensor failures
 2019-04-26 11:25:30 +02:00
Benjamin Vedder 0551117351 Some HW cleanup and documentation, fixed DRV8301 fault readout bug, added mpu_read_reg terminal command 2019-04-26 11:07:31 +02:00
Marcos Chaparro 6d758b38f2 Detect current sensor failures 
2 failure modes added:
* On boot, when calculating DC offsets generate a fault if the offset is beyond
HW_MAX_CURRENT_OFFSET. Fault code reports which sensor is having issues (1, 2 or 3).
Most likely cause is a disconnected sensor, if hw has fault-detecting pullups.

* On runtime, in setups with 3 in-line phase current sensors, checks that the sum
of the currents is below MCCONF_MAX_CURRENT_UNBALANCE, with a configurable low pass
filter. If unbalanced current is high, it means a fault to ground, or a disconnected
sensor (this works at 0 Amp if hw has pullups in the sensor input to detect the
failure).

Maximiliano Cordoba 4a94d0ec4c Add command to connect a virtual motor with configurable parameters 
This commit adds a motor model running within the vesc firmware,and
from the vesc terminal a user or a test script can set the
mechanical load torque, inertia, phase resistance, Lq and Ld phase
inductances (this generic model includes IPM motors), flux linkage
and battery voltage.

Virtual motor parameters set at the command line should match with
vesc configuration, for example phase resistance, inductance and
flux linkage should match and have the correct observer gain.
Observer works with the virtual motor, with some hiccups during
startup
For solid results its better to use sensored mode. If vesc is
configured to use an SPI encoder the virtual motor phase angle
will be injected as an encoder angle readout.

For safety PWM outputs are disabled during simulation.

Marcos Chaparro b155d5219a Basic SinCos encoder support 
Reads sine and cosine on ADC_IND_EXT and ADC_IND_EXT2, usually
used for ACCEL and REGEN inputs. Provides offset and gain
compensation and is implemented using floating point math.

Note it includes the full mc_interface.h into encoder.c only
to access the ADC readings, and no filtering is performed on
the signals.
