Hi
We bought a treadmill around two years ago, we hadn't used it much (either too lazy or too busy) so usage was around 6-10 times a year. Anyway the wife decided to go on it but it beeps now when starting up, flashes a date of manufacture on the led display followed by a E01 code.
I called the company that made the thing with no response so I emailed them and got an email back a few days later, basically I would need to purchase a new board at $270. I took the board to a component store and they couldn't 'fix it'.
The board has few components on them the main one is a chip "stc89c54rd 40c pdip40"
All the leds are working, the other capacitors must be working else there wouldn't be any leds lights on.
I was thinking about getting a bunch of these mcu from china as there only 0.43$ each and then copying the mcu software onto a blank one. But if the chip is encrypted, I wouldn't know what to do.
Do you think I should just buy the board (what if that goes dolally in two years as well!) or
attempt to clone it onto another chip?
I'm a newbie at electronics so I wouldn't know what to purchase to clone it if I went down that route. Do you have any recommendations on software or hardware (that can also copy encrypted chips, if it is)?
thanks and sorry for the long post.
