 2024-06-17 13:16:52 +08:00
linuswck d5a620c76b pd_mon: make transconductance user-configurable 
- hw change: different boards now have different gain settings in order
    to set a pd current range close to the ld being used
- transconductance and fin_gain params are added to flash with "Device"
    as key
 2024-06-17 13:16:48 +08:00
