Notes of VESC FW 5.03

VESC FW 5.03 is a great and long waited FW version.

Here is some 'maybe' issue observed in my testing with FW 5.03:

1. When current is at 30-50A, the motor may trembled some times(just fond on my test bench, not sure for real riding).
2. The control input is disabled in default and after FOC setup.
3. The inter-VESC communication through CAN bus is busier than former version, thus will have a traffic issue when remote signal exists on CAN bus too. So it is better to disable remote input before config VESC. If the VESC tool promotes 'All the VESC must have same firmware version' or 'can not read the firm ware version', there may be this reason.
