ATtiny IC’s

All of the ATtiny’s are basically the same apart from the number of actual IO pins and a few specific features. ATtiny24 / ATtiny44 / ATtiny84 14pinInternal osc +-10% without user calibration (ATtiny841 is drop in replacement with better accuracy) ATtiny85 8 pin ATtiny441 / ATtiny841 14 pinInternal osc +-2% without user calibration UART pins […]

ATtiny – Programming

Bootloader vs Programmer The ICSP programmer is needed when writing the bootloader or if you want to save program flash space and only program your ATtiny using the ICSP. When programming the ATTiny using the bootloader you use the TX/RX serial port (the ATTiny should be connected to your USB-serial adapter). The ICSP programmer doesn’t […]
