Program an Arduino pro-mini 5v 16mhz with a CP2102 USB to TTL without DTR pin (CP2102 with 5 pins)
Well, this is a short tip, mostly for me to remember. Arduino IDE should be configured as bellow.
And connections are so:
CP2101 +5v -> Arduino VCC
CP2101 GND -> Arduino GND
CP2101 RX -> Arduino TX
CP2101 TX -> Arduino RX
CP2101 3v -> Not connected (would be instead of +5v if it were an 3.3v pro-mini, the one with 8mhz)
As this model of CP2102 USB to TTL adapter don`t have an DRT pin, we hold the reset button on Arduino when sending, keep it hold during "compiling", and release as soon "uploading" appear on the IDE. LED`s on the adapter should blink, and the code now lives on your Arduino board.
As you may know, I`m a programmer, I work most in web projects, but not only. This area is a mess! Each day you have to recycle what you know in many ways. The thing is, a knowledge that change so often can`t afford wait to be translated to Portuguese for instance, at that time, the known will be already deprecated. English to me is a functional requirement. I can`t imagine my daily life without it. I have been studding English for serious since 2009. In this section you can see what I`m working on. Have fun as I do.
