Bug Report: Unimplemented Registers

ccut93
Associate III

Hardware: EVSPIN32G4-DUAL

Configuration: 1-shunt FOC, Observer + PLL

 

Bug location: register_interface.c

Registers in Question:
FLUXWK_BUS_MEAS
MC_REG_PULSE_VALUE, 
MC_REG_BEMF_ZCR
MC_REG_BEMF_U
MC_REG_BEMF_V
MC_REG_BEMF_W

Description:
When these registers are written to, board responds indicating they are read-only.  When I read from these registers, board responds indicating they do not exist.  Under register_interface.c, I see that the registers are listed under SetRegisterMotorX to give read-only, and are not listed under GetRegisterMotorX, which produces this behavior.

Hello @ccut93,

The write mode of these registers is only available if there associated feature is enabled: "Flux weakening regulator" for first parameter and "6Step" for other ones.
