Hello all.
Is it plan to enabled this feature on AVR soon ?
Is it also possible to add multi baudrate.
I use a RobotDyn Mega with WiFi on a Ramps 1.4 and a serial TFT on my printer, and Linux on my computer. I have some problems with 250000 baud on serial usb, but for the TFT, the only way to make it work is to set it at 250000.
So I use Serial1 at 250000, and WiFi at 115200 on Serial3 with some changes on the code like this.
// HAL/HAL_AVR/HAL_AVR.h
#define NUM_SERIAL 1
#ifdef USBCON
#if ENABLED(BLUETOOTH)
#define MYSERIAL0 bluetoothSerial
#else
#define MYSERIAL0 Serial
#endif
#else
#define MYSERIAL0 customizedSerial
#ifdef SERIAL_PORT_2
#undef NUM_SERIAL
#ifdef SERIAL_PORT_3
#define NUM_SERIAL 3
#define MYSERIAL1 customizedSerial1
#define MYSERIAL2 customizedSerial2
#else
#define NUM_SERIAL 2
#define MYSERIAL1 customizedSerial1
#endif
#else
#ifdef SERIAL_PORT_3
#undef NUM_SERIAL
#define NUM_SERIAL 2
#define MYSERIAL1 customizedSerial1
#endif
#endif
#endif
// Marlin.cpp
#if NUM_SERIAL > 0
MYSERIAL0.begin(BAUDRATE);
#if NUM_SERIAL == 2
#ifdef BAUDRATE2
MYSERIAL1.begin(BAUDRATE2);
#else
MYSERIAL1.begin(BAUDRATE);
#endif
#endif
#if NUM_SERIAL == 3
#ifdef BAUDRATE2
MYSERIAL1.begin(BAUDRATE2);
#else
MYSERIAL1.begin(BAUDRATE);
#endif
#ifdef BAUDRATE3
MYSERIAL2.begin(BAUDRATE3);
#else
MYSERIAL2.begin(BAUDRATE);
#endif
#endif
#endif
Not working for now because MarlinSerial don't support multi instance but I'm looking to scratch it.
