When using Go modules the TinyGo compiler doesn't find the TinyGo packages like machine | ERROR: undefined machine.I2C0 #4299

I borrowed a test program for the nodemcu with onboard oled ssd1306 display(it functions just fine on C or MicroPython code). This program is in the TINYGOROOT directory in the src/examples folder, I tried it in it's own standalone directory as well.

main.go

package main

import (
    "machine"
    "time"

    "tinygo.org/x/drivers/ssd1306"
)

BryanSouza91 commented 2 weeks ago

I overlooked it when I first posted this but it seems the problem is that I2C is not implemented yet for the esp8266 based boards.

You can find the I2C implemented in software from the following. @BryanSouza91

Thanks for that link! I'll give that a try!
