I just updated to Catalina Beta 10.15 and as expected, the software no longer starts. The same happens with both the Home and the Education version.

In the meantime you could use the early release of the new version, made available for the home edition of the EV3.

It is not possible to control the LEDs separately using the official EV3 firmware. You would have to modify the kernel drivers. You can only use the predefined patterns shown here. ULONG LEDPATTERNDATA[NO_OF_LEDS + 1][LEDPATTERNS] = { // LED_BLACK LED_GREEN LED_RED LED_ORANGE LED_GREEN_FLASH LED_RED_FLASH ...

It is not a protocol limitation. It is a sensor limitation. There is a microcontroller on the LEGO EV3 Ultrasonic sensor that cannot be updated so there is no way to measure more than that. So to measure more than 255cm, a 3rd party sensor is needed, e.g. https://mindsensors.com.

Recently in the scope of a pet project I have put effort into finding a way for systematic decoding of the rbf file to EV3G compatible high level blocks buildin upon David Lechner's disassembly work. Currently the project has over 95% coverage (all common blocks recognized) called EV3BrickMagic You can try the result online - http://ev3treevis....

I believe that this is the block that you are looking for: https://www.hitechnic.com/upload/545-HiTechnicEV3Color.zip The database listing downloads appears to be down, but the files are still available. Here's what I did to find the internal link: Pull up the download listings on archive.org: https://web.archive.org/web/20180203011745/https://www....

From a programming perspective I can't help you since I haven't programmed anything since the Mindstorms NXT. The simplest solution I can think of, without seeing your set-up, is to offset one of the motors and add a 1:1 gear drive using 16 tooth gears that would simply reverse the motor output on that side.

Thank you! The answer from jncraton did the trick. Summary: the direct download for the EV3 sensor block for the HiTechnic Color Sensor V2 is here: https://www.hitechnic.com/upload/545-HiTechnicEV3Color.zip The zip archive includes three files: (1) instructions (HTColorREADME.txt) (2) the control block (HTColor.ev3b) (3) a sample file demonstrating use ...

The easiest way for me, is using SPACE key. Press down and hold SPACE while dragging the programming canvas, the canvas should move with your cursor.
