PSoC 5
|
Core
|
OK
|
PSoC can be programmed & debugged.
|
I²C0 – 3V3 (IMU, Exp.)
|
Partially tested
|
Works well with the IMU, and with external sensors.
|
|
I²C1 – 5V (SCoP, pots)
|
OK
|
Communication with Safety-CoP works, Strain works.
|
|
Safety-CoP
|
Core
|
OK
|
PSoC can be programmed & debugged.
|
BLDC
|
Half-Bridge
|
Partially tested
|
Works. Current sensing is functional. Document gate signals, and optimize deadtimes.
|
Shorted Leads
|
Partially tested
|
Programmed to eb always Open. Need to test it Closed.
|
|
Temperature
|
OK
|
Seems right, changes when I heat it up.

Power
|
10V SMPS
|
Partially tested
|
Works. I should confirm the noise.
|
5V SMPS
|
Partially tested
|
Works. I should confirm the noise.
|
|
3V3 LDO
|
OK – after fix
|
Works after I changed the voltage regulator.
|
|
Voltage measurements
|
OK
|
Works. Proper values read.
|
|
RS-485

UI-IMU
|
IMU
|
OK
|
Tested accel + gyro in GUI, works well.
|

|
Power output
|
–
|
OK
|
Works. Tested up to 1A.
|
Protection
|
–
|
Partially tested
|
IOs seem fine. Have not tried sending out of range voltages.
|
FLASH
|
–
|
Untested
|
Known imperfections:
- 3V3 regulator: wrong footprint. Change reference (RT9064).
- Voltage seems low when USB is used to power circuit. Confirm measurement.
- Error on silkscreen (swap +VB and +5V)
- What’s causing the offset in the current sensor?
