Hi Im wanting to have a box that shows what the leds are showing how would i do this using project 2?

And I have two ports i believe, one /dev/cu.usbmodem1421 and the other /dev/tty.usbmodem1421 What do i do with these?

So i open the file with python loader and i get this.
Garretts-MacBook-Air:~ GarrettLeffue$ cd '/Users/GarrettLeffue/Documents/' && '/usr/bin/pythonw' '/Users/GarrettLeffue/Documents/stm32loader.py' && echo Exit status: $? && exit 1
Traceback (most recent call last):
File "/Users/GarrettLeffue/Documents/stm32loader.py", line 29, in

import serial

ImportError: No module named serial

How do i solve this?

I knew how to do this on windows but its the mac part i dont understand since I'm fairly new, can you actually talk through each step? I dont understand the myserialport or the python stuff. Can you talk through each of those steps in the most simplest way?

I have done everything in the how to on flashing the board. But i get to the part

Download the stm32loader.py Python script from https://github.com/espruino/Espruino/blob/master/scripts/stm32loader.py
Run python stm32loader.py -p MySerialPort -evw espruino_for_your_device.bin
For Espruino Boards add -k to the command-line. This will make flashing more reliable.

On Mac OS, MySerialPort will probably look a lot like /dev/tty.usbserial### where ### is a number. You can use the 'Tab' key to autocomplete once you have typed /dev/tty.usbserial

And i have no idea what it is meaning for me to do. and the link for more information isn't working. Any better tutorials?

Hello , i was trying to mess around and i found a code online https://gist.github.com/dsample/9126456 and it worked fine, now when i tried to go back to http://www.espruino.com/Project+2 and send this one i get random flashing and it wont stay on it, iv tried reset(); but that doesnt seem to help any ideas?

because whenever i try to change it, i get errors.

back to before is that the only line i need to change

What pin would i connect a battery to? Id rather not use the usbs and would rather solder, the power from the battery will be 5v? What pin do i connect to

this one? and change it to 120*3

var rgb = new Uint8Array(50*3);

Isnt in the code? does it look like 50 * 3

Where the function that changes the amount of leds? i have 120 leds and i cant seem to figure it out.

actually i believe the red and green are backwards on the slider and boxes.

Thank you so much :) Can you help me with the code now? iv pasted the code from the website but i have all the color boxes set as red but the leds are green?

i have roughtly 57, okay but they are 5v leds? would i just hook the green wire up and then the two wire that are seperate power supply? or would i hook the 3 up and the two?

I have he ws2811 leds hooked up the 3 that are in the connector go to with and grnd then red and 5v and then green pb15.

I actually have the thing saved on it correctly now, and all the touch works but when i hook up the leds, the screen goes away? any ideas?

And i did update it.
