installing software on electric bike

[mustafa_mobilx]

Hello,
I have a Volta VSM 48V electric bike. speed limit 25 km. I tried to install xpd software with ttl but it didn't work. I made tx, rx, gnd, 5v connections but it doesn't see it. Need help with software. I want to connect an alarm but there is no socket in the engine control unit. I don't know where to connect the outputs. thanks.

I installed something similar. Actually, it’s more like this here



I just fed it positive and negative from my displays 48v source. Turned out, I only needed battery power to have the alarm work. The remote turned the alarm off/on. The alarm was motion sensor. I didn’t connect anything else so, I didn’t have wheel locking or anything fancy. It worked fine. I ultimately took this out because it was draining about .4 volts a day.

Is this two questions (ability to connect and install/modify firmware; connecting an alarm for your ebike)? For firmware, you need to make sure you're using the right protocol, (UART, CANbus). For the alarm, you don't necessarily need to connect it to the controller unless there's some functionality (e.g. lock the motor so you can't roll the bike away) that the controller supports that you want to leverage.

If "xpd" refers to Anpaza's XPD here on ES, it isn't something you can install on the controller.
You have to install it on your computer.

Then, for the specific models of controller it is designed for, you can use it to alter certain specific settings of those controllers.

If your controller is not one of the ones its' designed for, it wont' be able to communicate with it, and it won't work.

If it isn't made for XPD but XPD does communicate and actually write to it, doing this could brick the controller or change settings in ways you won't know the results of, leaving the controller unusable and/or damage or destroy it. .


Most controllers are not programmable in any way. If you want a programmable controller, you should be sure that the one you buy is designed and built to be, and that it comes with the programming software and hardware, and that it can change the specific settings that you want to be able to change, within the ranges that you want to change it to.
