Why was the Atmega16U2 used on the Arduino UNO as a USB to Serial converter?

This is the first time that I realized that extra SMD IC near the USB port of the Arduino UNO is actually a fully fledged microcontroller, I thought that it was just a USB to Serial converter. Further research into this chip left me with more…

ISP with 115200 baud

I have a serial ISP programmer of protocol type "stk500v1" which expects 115200 baud data rate. I have used it successfully with Atmel Studio by calling avrdude manually (custom tool) in the past. This just involves the avrdude option -b…

Is this a USBasp I can use with Arduino?

I bought the following USBasp off of Aliexpress. The Arduino UDE doesn't recognize it. When I try to run avrdude with it, it says: avrdude -cusbasp -Pusb -patmega328p avrdude: error: could not find USB device with vid=0x16c0 pid=0x5dc…

Trying to verify that Arduino Pro Micro ISP is working

I'm trying to program an Arduino Pro Micro with another Arduino Pro Micro. The purpose is to verify that I can use this Pro Micro board reliably as an ISP to program another Arduino device that does not have a USB interface. These are actually Pro…

Changing parameters in Arduino without the IDE

I’m installing Arduino-based well monitors in my local community. Each well is different and has slightly different parameters and several hardware variations. Currently, when I need to make a program change I have to uninstall the Arduino, bring…

ISP - Wrong direction frying ATmega

I tried to flash my ATmega328P-PU not over the Arduino but over a self-made programming board and an USBasp. The problem is, I made the board a while ago and didn't mark which direction the 10-pin connector has to go. My question is, can I fry the…

16u2 programming

How does one go about programming the 16u2 on an Uno? I have the isp header (for the 16u2) hooked up to another Uno programmed as ArduinoISP I'm not talking about DFU or USB->UART, I'm talking about using it like a standalone chip (Like, say, a…
