SPI anomaly :(
Great! you are right! i changed the ISR to this: ISR(SPI_STC_vect) { uint8_t bufferSPI; /* Return data register */ bufferSPI = SPDR; USART_Transmit(bufferSPI); } i've...

addressable nursing call system
Two wire communication? how can? Your distance is about 150m, there will be a lot of noises that causes a poor successful communication, i recommend you to use RS485 protocol or...

HELP!!! i have spoiled 3 atmega8
hi your problem just like mine in the past. In the datasheet it's written that setting CKSEL fusebit would affect osc frequency (ie. ext or internal and so on). It's true that u...

Interfacing atmega16 with Ping sensors
i've used ping sensors using my ATMega8 clocked at 16Mhz. The datasheet itself doesn't provide detailed information. The pulse diagram that drawn in the datasheet is little...

AVR with Radiometrix FM
it seems your environment was too noisy. i've had that kind of problem too few times ago. really frustating, on 20 times transmision it is lucky one data arrived correctly. then i...

More LCD Trouble
no, you dont have to send it back. heheh. You can try to make a virtual ground. try using few divider resistor. on the top most node connect your positive supply, on the bottom...

Need help, strange behaviour on controlling servo motor!
no, i dont use any driver. just connect the servo directly to my atmega8. but i dont get it, i was make the same kind of controller but using AT89S51. i controlled up to 12 servos...
