Re: New "TSDZ2 Torque Sensor Central Motor"

If it doesn't damage the motor, I can still try it out as a training tool... hi, I finally ordered a 36V TSDZ2 and it should arrive later this week or early next week. The battery however will arrive later. Can I still install the motor and ride without a battery with the motor off? Or will this da...

Re: New "TSDZ2 Torque Sensor Central Motor"

On the other hand, purely functionally, the stock firmware is quite good. Don't expect the open source firmware to give a radically better riding experience or to dramatically extend battery life. Thank you tomtom50 for this. I've actually customized the stock firmware and I also like it as it is. ...

How do you use tour mobile phone? Do you prefer to use it as a LCD or you just keep it at your pocket while you pedal?
I use it as an LCD on the handlebar. It works in the background with switched off screen as well, so you can put in pocket too.

Re: New "TSDZ2 Torque Sensor Central Motor"

fyi, a graph created by data sent from my VOAMCA firmware. This firmware is actually the same as factory default, I just enabled to send voltage, ampere and cadence values to display and a firm assist level set possibility. It contains data from a 40Km route. https://raw.githubusercontent.com/wptm/v...

Re: New "TSDZ2 Torque Sensor Central Motor"

What is your plan?? My Arduino and SPI TFT setup is a proof of concept only. A mobile phone connected to TSDZ2 via bluetooth is the best display imho.

Re: Improving original firmware - TongSheng TSDZ2 mid drive motor

I did a quick test with the XH18LCD and its ST7735S: After UTFT() the LCD is still white and after UTFT_InitLCD() it switches to a random noise picture (or the last displayed image if still in the memory of the LCD). I have the same experience (white and then random noise/last image) with KMR-1.8 S...

I've started to investigate the code. I use a Mac, so I started to figure out how to compile it on macOS. I've found SDCC - Small Device C Compiler http://sdcc.sourceforge.net which works under macOS as well. I've made the following script to compile it with SDCC: https://github.com/wptm/TSDZ2/blob/...

I have a persistent annoying thing with my TSDZ2: a drag when I try to use it without assist. It's there since I bought it, 600 Km before.
