Reading is a bit more difficult because the signal is asynchronous. You can add — 2K ohm resistors if you want to be extra careful. If you have gone into the Arduino IDE preferences and checked show verbose output during upload, the command line for avrdude which attempted to burn the bootloader will be shown to you. Thank you for your fast reply! I have read about adding resistors in series with the serial connection. Arduino IDE. This is a great, detailed tutorial with sharp pictures, details and forgive me for this understandable English. CaptClaude CaptClaude Reply 2 years ago.

    The amateur programmer's first recourse may be to use delays to properly time the output data stream. This has the drawback Posted in classic hacksTagged attiny, serial, uart And then of course setup for the next start bit.

    void setup() { (); } Basically this gives you the advantage of Asyncronous Serial communication, but uses a clock line to time the bits allowing for full duplex operation without the ATTiny having to time out the Serial baud rate .

    This is a little more tricky but can save a lot of processor time and code complexity. I was getting garbage output until I changed the Baud rate from to If I want to disable the reset pin again and get that additional digital pin 5, I would replace the hfuse:w:0xD5:m with hfuse:w:0xm Of course, that means I would need to use the high voltage programmer to unlock it again if I want to use ISP programming with it again.
