Replacing the firmware
Posted: Mon Dec 14, 2020 7:42 pm
Hi to all.
I assembled a Geiger Counter and successfully log it through the serial.
I was thinking of replacing the stock firmware with a version that would not report once per second as now, but send a message on each click. So no accumulation or computation would be made on the microcontroller, just send something on each led blink. All the accumulation, averaging, etc, would be done on the host. Or the micro could send a timestamp, and then this could be used as a hardware random number generator, for example.
I see there are the sources, and it would be easy to modify from them, but Is there a tutorial on flashing the ATtiny2313? Never flashed one of those, only some old Microchip stuff (PIC16, PIC18) and "powerful" stuff like Cortex-M or ESP32s.
