Standalone Atmega8u2 gotchas? - 3rd Party Boards - Arduino Forum
2012年2月18日 · I put an Atmega8u2 on a circuit board together with a crystal and an ICSP, plus power and some peripherals I want to control, including a Atmega328 (this part is similar to an Uno.) I also hooked up an USB connector, with TVS to ground and 22 ohm resistors. And the 1uF capacitor for the USB regulator. And pulling /RESET up to +5V through a 22k resistor. I want to program this through ICSP ...
Diffrence between ATMEGA 16u2 and 8u2 IC. - Arduino Forum
2012年2月13日 · Hi, I purchased an Arduino ADK R3 and was going thru all the pin-out and IC. On the Hardware page of Arduino website it is mentioned that the ADK comes with either 8u2 or 16u2 IC. As far as I know, this IC is used for data communication between the board and USB. I would mainly like to know what are the differences between the 16u2 IC ad the 8u2 IC. Also what are the other uses of it on this ...
Atmega8U2-Is there an Arduino-compatible bootloader for this?
2017年11月5日 · Picked up a bunch of these ATmega8U2's a while back for less than a dollar each. After a few quick searches, all I find is people updating the firmware and boot loader for these when used as a USB bridge, instead of being used as the main microcontroller. Is there an Arduino-compatable bootloader for these, or even a method to write using the Arduino IDE and then ICSP the program into the 8U2 ...
How put ISP program on atmega8u2 - Arduino Forum
2025年2月16日 · Some years ago I made simple PCB for atmega8u2 with USB connector, ISP header and similar header for ISP programming and somehow programmed this as ArduinoISP programmer. When connected to USB it was reported as Atmel Corp. atmega8u2 or something like that. When ISP cable from the second connector was put into clasic Arduino's ISP header, the other Arduino could be programmed via it (with ...

Bootloader un ATmega8U2 - Français - Arduino Forum
2016年6月17日 · Bonjour tout le monde, pour un projet de clone arduino, j'aurais besoin de booloader un ATmega8U2 sans utiliser le mode DFU et le logiciel Flip. J'imagine que c'est possible par ICSP mais j'avoue ne pas trop savoir m'y prendre. Est-il possible de le faire avec un autre arduino en mode ISP a partir du logiciel arduino avec la commande "Graver la séquence d'initialisation" comme on ferait pour ...
