challenge for two way communication betn PI and AVR ATmega16 - Raspberry Pi Forums

-

dear friends,

trying 2 way communication between pi , atmega16,

not been able success, please guide if can.

2 way communication atmega16 atmega16 through uart.

same trying pi gpio uart pins , atmega16 not working,

using 8mhz crystal atmega16. required configure start external clock(crystal)

can probable reasons.

uart uart should work.

pi's gpios 3.3v need use voltage divider (pair of resistors) drop arduino tx pin 5v 3.3v pi's rxd pin. other direction should fine.

you'll want disable pi boot messages (which sent uart) , pi login via uart.

hello, im confused uno r3, uploaded code quite few months in uno, working fine. now without having altered of circuits, trying upload code changes,im getting strange error "avrdude: verification error, first mismatch @ byte 0x0000          0x0c != 0x62" i tried research able solve issue,  im running kind of fuse bit being changed or clock speed altered, im pretty sure did not play around these items. any people, please . . thanks taz Arduino Forum > Using Arduino > Installation & Troubleshooting > avrdude: verification error, first mismatch at byte 0x0000 0x0c != 0x62 arduino
