6 | 19 | ## Quickstart |
7 | | -### Use Arduino Micropython IDE |
8 | | -- Download release https://github.com/arduino/lab-micropython-editor/releases |
9 | | - + For mac, linux or windows just download the appropriate package and unzip |
10 | | -- Then open Micropython IDE and click 'Connect' |
11 | | - + assuming your JEM is plugged into computer and turned ON |
12 | | -- You should see list of files / directories on your JEM |
13 | | -- REPL terminal also available |
14 | | -- You can edit a file and click the 'Save' button to flash the code to JEM |
| 20 | +### Update your JEM2 with latest code over serial |
| 21 | +- In Google Chrome Browser (must be chrome) go to: https://jem-dev.onrender.com/ |
| 22 | +- Connect your JEM2 to your computer via micro usb |
| 23 | +- Turn on the JEM2 with the side power switch |
| 24 | +- Click on **Serial Connect** button and select the JEM port |
| 25 | + + Mac / Linux: **usbserial-DP04I8FJ (Example)** |
| 26 | + + Windows: **COM3 (Example)** |
| 27 | + |
| 28 | +- Wait about 5 seconds |
| 29 | +- Below, click the **Load All** button next to the **Official KitLab Kits** section |
| 30 | +- Select the **JEM2 Demo Kit** Sync button (may take 10 seconds to sync) |
| 31 | + |
| 32 | + |
| 33 | +- After selecting, navigate to the **Edit** tab (near lower right hand corner) |
| 34 | +- You should now see the **JEM2 Demo Kit** project in the File Explorer to your right |
| 35 | + + If it's says something else like **MicropythonBoard** just click on that and you should see the Demo Kit option |
| 36 | +- Now click the **FLASH TO JEM** button and wait for prompt to reconnect to JEM2 after upload |
| 37 | + + This can take anywhere from 15 seconds to a couple minutes depending on big the update is |
