Description of Change

This PR fixes Paripheral Manager issue related to detaching rx and tx in the same or different execution time which shall lead to stoping the IDF UART driver and shuting down the Arduino log interface if enabled.

Test Scenarios

PPP using UART0 rx and tx pins for communication.
UART CI Test Sketch.

#include "Wire.h"

#ifdef RGB_BUILTIN
#define LED_PIN RGB_BUILTIN
#else
#define LED_PIN 2
#endif

void setup() {
  // put your setup code here, to run once:
  pinMode(LED_PIN, OUTPUT);
  Serial.begin(115200);
  Serial.setDebugOutput(true);
  
  Serial1.begin(115200);
  Serial.println("Step 1: double end() call."); Serial.flush();
  Serial1.end();
  Serial.println("Step 1.1: first end() executed."); Serial.flush();
  Serial1.end();
  Serial.println("Step 1.2: second end() executed"); Serial.flush();
  Serial1.begin(115200);
  Serial.println("Step 2: detach RX1 and TX1."); Serial.flush();
  Serial1.begin(115200, SERIAL_8N1, 14, 12);
  Serial.println("Step 2.1: new pins UART1"); Serial.flush();
}

void loop() {
  // Blinking a LED to signal that nothing got into infinite loop within main task...
  printf("Loop...\r\n");
  digitalWrite(LED_PIN, HIGH);
  delay(1000);
  digitalWrite(LED_PIN, LOW);
  delay(1000);
  // this will detach both UART0 pins and stop the driver... no more printf|log output!
  Wire.begin(SOC_RX0, SOC_TX0);
}

Warnings
⚠️

Some issues found for the commit messages in this PR:

  • the commit message "fix(uart): Refactor UART test to detach only one pin":
    • body's lines must not be longer than 100 characters
  • the commit message "fix(uart): peripheral manager CI test adjusting":
    • body's lines must not be longer than 100 characters
  • the commit message "fix(uart_test): do not detach both UART pins":
    • body's lines must not be longer than 100 characters

Please fix these commit messages - here are some basic tips:

  • follow Conventional Commits style
  • correct format of commit message should be: <type/action>(<scope/component>): <summary>, for example fix(esp32): Fixed startup timeout issue
  • allowed types are: change,ci,docs,feat,fix,refactor,remove,revert,test
  • sufficiently descriptive message summary should be between 10 to 72 characters and start with upper case letter
  • avoid Jira references in commit messages (unavailable/irrelevant for our customers)

TIP: Install pre-commit hooks and run this check when committing (uses the Conventional Precommit Linter).

@me-no-dev - Not sure if this change would be considered a Breaking Change - stopping the UART after both RX/TX pins are detached.

Pull request overview

This PR implements automatic UART driver termination when both RX and TX pins are detached from a UART peripheral, which can occur when another peripheral (like I2C) claims those pins. The fix includes safeguards to prevent unwanted driver termination during legitimate pin reconfiguration operations.

Key Changes

  • Added logic to terminate UART driver when both RX and TX pins are detached
  • Implemented callback muting mechanism in uartSetPins to prevent driver termination during pin changes
  • Moved debug UART reset from HardwareSerial::end() to uartEnd() for centralized cleanup
  • Updated tests to avoid detaching both pins simultaneously, which now triggers driver termination
