How to set RX and TX pins?

[antonvh]

I have a different board. My rx and tx pins are 18 and 19. How do I set them on init?

I expected something like this would work in setup{};

myDevice.setSensorDistance(&sensorDistance);
myDevice.init(18,19)

Hi,
Currently specifying pins for RX/TX is not required since I simply use the global Serial/Serial1 object defined from the core framework of your mcu.

MyOwnBricks/src/global.h

Lines 25 to 31 in b36895a

	// Enable Serial CDC (USB) for Atmega32u4 (Pro-Micro only for now ?)
	#if defined(ARDUINO_AVR_PROMICRO)
	#define SerialTTL Serial1
	#define DbgSerial Serial
	#else
	#define SerialTTL Serial
	#endif

Note that Software Serial with custom pins is not supported for now.

Ah ok. I was hoping for software serial on esp32 custom pins. I'm not familiar enough with Arduino/c++ to add myself. I will look for another library instead.

Ok, it should be straigthforward™ to declare your Software Serial object in global.h

If you are using https://github.com/plerup/espsoftwareserial/ (the first softwareserial lib I found in google for ESP).
Something like that:

#include <SoftwareSerial.h>
...
#if defined(ESP8266) || defined(ESP32) // Check these flags I'm not 100% sure
#define MYPORT_TX 12
#define MYPORT_RX 13
EspSoftwareSerial::UART myPort;
#define SerialTTL    myPort 
#elif defined(ARDUINO_AVR_PROMICRO)
...

And you have to rewrite occurrences of SerialTTL.begin in the project (https://github.com/search?q=repo%3Aysard%2FMyOwnBricks%20SerialTTL.begin&type=code) with something like that:

#if defined(ESP8266) || defined(ESP32)
SerialTTL.begin(<baudrate>, SWSERIAL_8N1, MYPORT_RX, MYPORT_TX, false);
#else
SerialTTL.begin(<baudrate>);
#endif

Let me know how it goes.

EDIT: Modifications of SerialTTL.begin added.

Thanks for your help! We still couldn't get it to work. Ultimately we solved it differently. Our code is here: https://github.com/ste7anste7an/bluepad32_arduino
