Unused GPIO ports not initialized with weak pull ups #1

Open joeygold opened 3 months ago

joeygold commented 3 months ago

The project code bldc.x doesn't completely initialize the unused ports and correctly terminate them in to weak pull up or down

On mclv-48v-300w J11 (XPRO1 Header) Pin 16 - If you touch PIN 16 the motor stops

J11 -PIN16 --> DIM:198 -->dsPIC33CK508MP508 pin 49.

a weak pull up is needed in the code port_config.c function

ifdef TRISD

    **CNPUD = 0x0100;**  // Joseph  Make pin49  weak pullup on MCLV-48V-300W
    TRISD = 0xFFFF;
    LATD  = 0x0000;

PIN16

Thank you, We acknowledge the issue and can confirm that it is a recognized problem. This is because of incorrect configuration of PCI fault, a fix has been implemented and will be included in our upcoming release.

Thankyou. Can you clarify PCI ?

The configuration of the PWM Control Inputs (PCI) in this project is incorrect, resulting in the PWM being turned off.
