I wanted to know if I can upload my skecht through a proto shield (via port TX and RX?) without using the usb plug?
I am already powering my board with the 5V and gnd, the board works.Then I tryied to connect the TX and RX pins of my board directly to the usb cable but it didn't work.
So, how can I upload programs without using the usb plug, and possibly through a shield?
I am asking because I have built a casing that includes interfacing (with my kind of plugs) and it's own "wall" usb plug. the arduino board is inside the box
Thanks for your answers
You can upload a sketch without using the arduino on-board USB plug. However that just means you would have to have another USB serial convertor chip installed on the shield board with it's own USB plug. I don't think this is what you have in mind. I have no idea what a 'USB wall connector' is but it just sounds like you need a physical cable connection for the arduino's USB jack and whatever connector type you have installed into your project box?
