ADC internal voltage reference accuracy?
Testing the Tiny13V internal Vref 1,1 (datasheet will tell you that it is 1,0 - 1,2V) I have found that the tolerance is really near 10%.

Setting high a bit on PORTE only rises level to Vcc/2
What is the type of your measuring instrument? Voltmeter, oscilloscope? Take a look at the pin using an oscilloscope. If you have a type of pulse there, then using a voltmeer...

ATmega88 USART Receive problem
Oh, I see. I will try all those, this afternoon. Althought, I have used the UART debuging the mega16 (via JTAG interface) in the past and I had no problem. I also tried those you...

ATmega88 USART Receive problem
Yes, I have check it. At 0x0012 there is the rjmp instructions that send the cursor at the Receive complete ISR. But, this is not the problem. The program gets in the ISR but the...

ATmega88 USART Receive problem
All the electrical connections seem to be well. I have checked the data on the RXD pin with the oscilloscope and it is really the 0x55 (at 9600bps as I expect) with one stop bit....
