Mod USB-COM adapter, which will save your nerves when flashing the Arduino Pro Mini and not only
Are you flashing the Arduino Pro Mini? Are you tired of pressing the reset button to fill in your sketch?
Often, the first time it does not always work, and you have to catch that moment, between compiling and loading.
So let's fix it.
Whichever adapter you have, IDE always sends a reset signal when flashing. The question is whether we have a conclusion on the adapter.
')
There are different adapters:
Many already have a controller reset pin - but they are significantly more expensive. Accordingly, they are bought less, which means they are delivered less to our stores, as a result, they are bought less. Straight vicious circle.
Often buy the cheapest adapter:
Cheap adapter never feel sorry to burn - everything happens. You can pick it and experiment, but with a little expensive one, the toad presses, better let it lie in a sideboard, in a box.
Those who know how to solder and understand the essence, they never buy what you can do yourself, because creating yourself is more than pleasant. I think many will agree with me. Yes, there are those cases when time is more expensive and easier to buy ready-made than to waste time on revision - but this is rare.
Therefore, I suggest you improve your Usb-to-Com adapter. And those who are just going to order, count ... For the price of 1 with a reset, you can buy 3 pieces without a reset and redo it.
There is nothing complicated.
On the PL2303 chip, there is a 2nd leg with a DTR signal, to which the IDE program already sends a reset signal when flashing, so why don't we use it.
The Arduino Pro Mini already has a DTR output, but not at all. The DTR signal is connected via a capacitor to the reset pin (reset),
Therefore, if you want to use, for example ATmega 8 or 328, then for auto-reset with firmware you need to install a 0.1 μF capacitor.
