SERIAL_TX_BUFFER_SIZE/SERIAL_RX_BUFFER_SIZE are not defined

Board

custom esp32s3 board

Device Description

Custom board with ESP32S3 and FUSB302 chip connected to USB-C port. The problem is unrelated to the board.

Hardware Configuration

ESP32S3 with FUSB302 i2c chip connected. The problem is related to SERIAL_TX_BUFFER_SIZE not being defined for the FUSB302 library.

Version

v3.0.4

IDE Name

Arduino 2.3.3

Operating System

Linux

Flash frequency

40MHz

PSRAM enabled

yes

Upload speed

921600

Description

I am attempting to use the FUSB302_UFP library, which fails to compile because it expects SERIAL_TX_BUFFER_SIZE to be defined. Performing a grep, I see it is also used by the MobaLedLib library and possibly several others. Using a hard-coded value may be problematic, so this may require more work with HardwareSerial.h to figure out what the current size is.

Sketch

#include <Wire.h>
#include <PD_UFP.h>

#define FUSB302_INT_PIN   12

PD_UFP_c PD_UFP;

void setup() {
  Wire.begin();
  PD_UFP.init(FUSB302_INT_PIN, PD_POWER_OPTION_MAX_20V);

  Serial.begin(9600);
}

void loop() {
  PD_UFP.run();
  if (PD_UFP.is_power_ready())
  {
    Serial.write("PD supply connected\n");
  }
  else
  {
    Serial.write("No PD supply available\n");
  }
}
