If your m8 has the as-shipped factory default fuse settings, it will be running at 1 MHz. hex file will have been built for an m8 running at 16 MHz. Sorry i forgot to mention that, i chose arduino ng or older with atmega 8, then built it. set the data bits, parity, and stop bitsĬonfig |= 0x80 // select UCSRC register (shared with UBRRH)ĭoes it keep any connection with what i am searching for ? *_ucsra = 1 4095, so switch back to non-u2x mode if the baud rate is too Uint16_t baud_setting = (F_CPU / 4 / baud - 1) / 2 Void HardwareSerial::begin(unsigned long baud, byte config) This is a code snippte from hardwareserial.cpp. Please help find out the possible errors and suggest changes. Is there any problem with wrong baudrate getting set ? I have set the F_CPU to 1 mhz, because im using it for atmega8 running at 1 mhz. Whilst using this code on arduino, i saw values being printed, continuously, but now nothing prints but the scroll bar keeps moving on its own as if blank spaces are being print. Setting to Verbose output during compilation, i got the hex file which i burned on the atmega 8 using command line.īut when i connect the tx pin of the mega8 to the rx pin of the serial to ttl converter and open up my serial monitor in the arduino ide, i see nothing, no values show up but the scrollbar automatically starts moving as if blank spaces are being print. The thing is, i have an atmega 8-8pu, running at default 1 mhz. I have this code nicely working on my arduino Uno. PinMode(IRemitter,OUTPUT) //IRemitter pin set as output Serial.begin(9600) //Enable serial communication Int IRemitter=2 //Pin 2 on the arduino board used the ir emmiter pin Int IRpin=A0 // Analog pin A0 used as an analog input I have a problem, please take a look at this code first.
