Using Arduinos with the CH340G chipset...
#1

It took just a few days for my boards to travel from Portugal to the UK, so I'm now getting together the small parts - capacitors, resistors and so on - and will be putting components on the Tx board first. Before I do though, a question. I think I know the answer but I want to check... Blush

I've bought a couple of Arduino Nanos for this project, all have the CH340G chipset. I know that a resistor needs to be replaced with a capacitor on the Rx board, I think that's in order to overcome a problem of the Nano resetting itself when it is connected to a computer. As the Tx board won't be connected, I'm guessing there's no need to substitute components on that board?? (Apologies if this question has already been covered elsewhere, I couldn't find anything though!)

You are absolutely right! We don't need to be concerned with the auto-reset on the TX board, we only connect it to PC when programming or upgrading software.

Thanks for confirming that, Werk_AG. I know nothing about the Arduino so I'm having to learn from the beginning... Rolleyes

A new world is opening to youSmile
You just have to download the Arduino IDE (1.5.8 or newer), add the required libraries, always supplied in the WeatherDuino Pro 2 software packages, check and edit some user configurable options clearly identified on the code, upload to the Arduino, and that's it.

Just to add to Werk's post above.
In the IDE options you need to set the board type to Nano and the correct com port (as shown in the device manager).

Ooops, sorry, I thought I posted this reply yesterday but it's not showing... Huh

Yes, it is a whole new world to me, I just need to find the map for it Big Grin

I've already downloaded the software, connected a Nano to the computer and I think, successfully programmed it. Just starting to put some of the components on the Tx board so hopefully I'll be able to test it fairly soon!!

Thanks for the good news. Programing the Arduino is really easy. Before upload the code, always check the user options (very few on the TX software) . Any doubt, we are here.

Just a hint. When you start to test your TX board, try to have it powered from the 12V connector and not just by the 5V from USB.
