【CW32】cw brushless balancing car

It’s my first time to participate in the Lichuang training camp. The free prostitution coupons are really good, so I must first thank Jialichuang! ! ! ! !

There is also the board that has been used for so long. It’s nice that the fourth tier is free! ! !

The main control uses a cw32 microcontroller. The libraries and routines released on the official website are relatively complete and basically sufficient. The main control board and driver adopt a layered design, mainly because of the fear of insufficient resources, which makes it easy to expand and write programs. Interested friends can also Directly drive the driver board and use other microcontrollers or Linux boards to control it.

The driver IC uses EG2133, and interested students can also choose other models. I won’t talk nonsense about the specific parameters. Friends, you can read the data sheet by yourself.

Physical picture of the main control board:

I didn't solder the crystal oscillator to save money and laziness, and there are currently no such high requirements.

But I can do without it, but I can’t live without it! !

The program only writes a display program, which will be perfected and released later. Because there is no 0.96-inch screen, I used a 0.42-inch one, which is barely visible.

The splicing effect looks pretty good, just a bit high.

Actual picture of driver board:

If you are poor and have no money, your other half will not be able to weld.

There are no functional problems, the waveform display is normal, and other things are still being debugged.

There is something wrong with the specifications of the bootstrap capacitor of the driver board. You should choose 4.7-10uf. The withstand voltage value depends on how many V you supply to the driver chip.

Interested students can also make their own modifications. It is best to send a private message before designing. The bugs I find may not necessarily be updated to this one.

The software part may take a little longer and will be updated after it is written.
