Hello , I'm interested in how to use and make work V-USB on Arduino Atmega328 chip , and connect it to the computer without any bridge ( atmega 8 ) . I would be very greatful , if you give me step by step tutorial or something like this . thank you in advance
as I discovered , AVR chips has it's own internal clock divider , and it divides 8MHz on 8 and it works on 1Mhz ? please , can anyone solve this problem for me ? or just advice what to do ? thank you in advance .
I used crystal and 2 caps and it worked fine . but I want to use this chips with it internal clocks . I am bit confusing BB1.name=Breadboard w/ ATmega328 Internal Oscillator BB1.upload.protocol=arduino BB1.upload.maximum_size=30720 BB1.upload.speed=57600 BB1.bootloader.low_fuses=0xE2 BB1.bootloader.high_fuses=0xDA BB1.bootloader.extended_fuses=0x05 BB1.bootloader.path=atmega BB1.bootloader.file=ATmegaBOOT_168_atmega328_pro_8MHz.hex BB1.bootloader.unlock_bits=0x3F BB1.bootloader.lock_bits=0x0F BB1.build.mcu=atmega328p BB1.build.f_cpu=8000000L BB1.build.core=arduino BB1.build.variant=standard
where should I add this piece of code ? I downloaded atmega328 bootloader and in this text doc , or where ?
Hello , recently , I've bought 2 chips of ATMEGA328P-PU with Arduino Bootloader - Uno . and I want to use this chips on breadboard without any crystal , with internal clock . so saw many tutorials and nothing was done . I used local tutorials but there are errors . first of all , first error was that there was not arduino_pins.h file in specified folder so I found this file (standart) in arduino IDE and copied in specified folder what was in error . then there were no erros but, when I upload ISP on arduino board and connect every pin to another Atmega328 chip RX and TX LEDs blink 2-3 times and that's all . then it says that there is error resp() 0x00;
everything works well when I try to program this external atmega with crystal and removed atmega on board .
All right , I am sorry Grumpy_Mike that I rejected your suggestion but I don't want to buy arduino Leonardo . the examples which are on V-USB have other basis or purposes , and they are very complicated .
I have got an brilliant idea , what happens if I buy simple USB mouse and interface it with arduino . e.g USB mouse would be as a USB interface and use some pins to control cursor ? is It possible. ?
