I’ve really hammered them over the past few months and they’re holding up very nicely.LEGO Education has tested and approved version 2.0 of Pybricks MicroPython as the official EV3 MicroPython application.MicroPython is a subset of Python used in microcontrollers. I bought these class 10 cards very cheaply from DX.com. If you are keen to take part in the beta trials, make sure you buy yourself a 4GB SD card (or bigger), so you can run the special firmware. You can also follow a thread on the ROBOTC forums where the devs post what’s going on. Make sure you keep your eyes peeled as a public beta program will start very soon, once things like LCD and LED control have been added.
Motor = nMotorSpeedSetting + round(error * nPfactor) Motor = nMotorSpeedSetting - round(error * nPfactor) #pragma config(Motor, motorC, rightwheel, tmotorEV3_Large, PIDControl, reversed, encoder) #pragma config(Motor, motorB, leftwheel, tmotorEV3_Large, PIDControl, reversed, encoder) This is the linefollower: #pragma config(Sensor, S3, colour, sensorEV3_Color) *!!Code automatically generated by 'ROBOTC' configuration wizard !!*// The don’t-bump-into-the-wall robot: #pragma config(Sensor, S4, sonar4, sensorEV3_Ultrasonic) As you can see, it’s not a lot different from what you’re used to with the NXT or VEX IQ or any other ROBOTC platform. I fiddled a bit more with it and made a (slow) line following robot:īelow you can find the source code of these programs. You can watch variables, sensors and motors.īelow is a video Tim Friez made of his robot not running into a wall. The debugging windows and all that fun stuff is also working. So the status right now is that there’s basic motor and sensor control, so it’s actually possible to make functional robots. However, I did mention in a previous post that I am also working on a massive rewrite of the suite to make it more struct-oriented. Some things like I2C will be different but so badly that it will take a lot of work to get it up and running. Pretty soon I can start working on porting the Driver Suite to the EV3. Many bugs and issues were fixed in the base LEGO VM that were causing issues, such as failed auto-id and I2C transactions. There has been an enormous amount of progress in the past few weeks on the ROBOTC for EV3.
