Upload this sketch to your Arduino via the menu File, Upload Using Programmer.
Whenever it is restarted, it pulses pin 2 low for a few microseconds. It does almost nothing, just shows you a blinking LED so you can tell the Arduino works. pulses a pin low for a few microseconds in the setup functionÄigitalWrite(2, HIGH) // pulse to send reset.does nothing at all with the serial port.You can use the USB to serial adapter which is built into your Arduino without modifying the hardware, cutting traces, adding parts, nor removing chips. What I need is a similar code, a kind of relay that forwards serial data between the PC and the AVR on the breadboard preloaded with a boot-loader, which uses just three of the Arduino Uno pins, like this: Arduino Uno-Target AVR I need something like ArduinoISP (which is a driver) that once loaded into Arduino Uno is able to take a hex file from the PC and burn it into a target AVR on the breadboard using four wires.Īrduino Uno as ISP: Arduino Uno-Target AVR Yes the piece of software I was asking for is a driver by all possible definitions.
#Eton Usb To Serial Adapter Driver how to
I do not know why the moderators of this forum have this mania of teaching you how to do hardware tricks on Arduino when much elegant solutions, like a driver, are possible. If I had followed such advises I would have destroyed my Arduino Uno by now. I was suggested in the past to do all kind of changes for various projects. I do not like to make any hardware modifications to my Arduino Uno R3.
