Heard across a street. Highly intelligent. A bike alarm like no other! $210 CAD. Direct from manufacturer: $120 CAD.

Over the past few years, I tried a number of different micro-controllers to design the system with. It started with an Arduino Uno, then went into different sizes and capabilities until it ended up in a different Atmel AVR.

Now, with the project nearing completion, Covid has put a stop to completion of the design. The micro-controller is not in stock, or the price has risen unviably high, or both.

Thus, I’m forced to select a different micro-controller. This is not a trivial exercise, as it requires getting to know the damned thing, finding sources and suppliers, establishing new hardware procedures, building test circuits, finding out how to write code to it, porting all the application code to it, then testing the whole shebang in the hope that it won’t harbour an unforeseen, insurmountable obstacle!

And restarting from scratch is not something which I wanted to do at this late a stage of development! <sigh>

Attempting to talk to the new micro-controller, in the hope of writing a simple program to it.
Hoping to write a test program to it. Does this particular uC have a bootloader? It should!

  1. Sure enough, the bloody thing did not work. It could be anything: the 6-pin to 10-pin mapping which I had to manually do, pin by freaking’ pin; some setting in the Arduino IDE; the programmer’s cable’s connector being interpreted the wrong way round; the particular “core” I used to add support for this particular micro-controller; or just a single wire missing, or loose, somewhere!
    As I said: Not the sort of thing I wanted to dig into, at this late a stage!
