I have been working on this project for almost 4 weeks now. I havent had any issues with Arduino Leonardo. I recieved the Core last week and I was playing with it and now I am running into few issues.
I tried to powerup the core with 3v3 and Gnd, which ended up me fully flashing the device. Now it works fine with no issues. From this day onwards I have been powering it up via Vin [Resolved i believe]
I introduced PS2 barcode to Core and I ran into few problems, which I am trying to solve with the help of ScruffR. I am getting weird characters [In progress]
Here is the new challenge I came across and I need your help to resolve it. Setup is provided below.
a. The barcode reader requires 5V so we powered up the barcode
b. Both arduino boards are powered by USB
c. After doing all these, I am not able to upload/flash code to the Core via Web IDE
d. I am getting Error 500 or its blinking Cyan
I assumed the problem was with network and then tried it at a different place and the problem persisted. I flashed the device using DFU mode and things were back to normal.
I tried to do something with an SD card which requires 5V. I took the similiar approach to this project. I connected the Arduino Leonardo for 5V. I got the same problem as before. I couldnt flash the the code through Web IDE. I then flashed the particle core using CLI and things were back to normal.
Can anyone let me know what I am doing wrong here? I am thinking of trying the following option:
a. Use voltage booster on 3V3 to boost 5v
I am open to suggestions at the moment. I would really appreciate any feedbacks or leads on this matter.
