OK - I found a version of the ArduinoISP sketch that supports a slow-speed option for the SPI programming: https://github.com/adafruit/ArduinoISP/blob/master/ ArduinoISP.ino. By defining the LOW_SPEED macro I was able to reprogram the  ...
ATtiny13A's timer appears to be very inaccurate, is it normal? [closed]
https://electronics.stackexchange.com/questions/33 ...
Oct 19, 2017 ... I wrote this blink program for my ATtiny13A and tried to measure the accuracy with an Arduino Uno but the timer seems to be quite inaccurate. On the ATtiny I am running on the internal 128KHz clock and using timers to make ...
