How to do this in Labview ( pushing a button)

[Blokk]

No need to say sorry. 🙂 It is just extremely difficult to say anything when I see photos of some unknown printed circuits 🙂

Some advice: try to find someone who has some knowledge about basic electronics at least, and who could give you some help to figure out whether it is possible to access the button wirings in this piece of electronics.

Warning! Make it 100% sure that there is not high voltages involved! Do not connect the device to the wall plug when you temper with it. Please ask for help from a qualified personal (electrician, etc) before you do any further work on this.

I had a second look at the photos. It is a pity this product is not hacked yet, I see there is a serial port connector (COM 6). Though, I have no idea what is that port for, so it will not help...

I guess the physical buttons are on the other side? I have no idea about the structure of this PCB board, so I cannot really tell if it is easy or not to access the buttons. Maybe you can figure out from the button side, but you might do permanent damage...

Edit: and if I was you, I would also consider the legal aspects of what you are doing. I am pretty sure that the manufacturer does not give permission for such hacking or reverse engineering of their product. So I advice you to think about these things as well before getting into trouble (i am not a lawyer, and this advice is general in nature and not to be taken as personal professional advice 😉 )...

Thank you. I feel so dumb lol SCIFIT is refusing to give us the schematic of the board or sny info. I'll take a look at the button and how they connected today. Thank you again 🙂

Good luck, and see my edit in my previous post!

Well  USB, COM, I2C, MODBUS and a JTAG 🙂   (Oh, missed the sound 😉 )

Seems to be made for communicaion 😄

Have a look if you have a Hackerspace or MakerFab around.

If you just want to control the break force:

I assume that there is some sort of elektromechanical /or magnetic  break in the bike and that you are able to identify  the cable to the cotroller board to it.

Get the datasheet of that break and monitor the wires.

 J25 looks like the connector from the foil buttons. Be carefull with this plastic cable, they are hard to repair 😉 BTDT
