Re: New "TSDZ2 Torque Sensor Central Motor"

When it comes to magnetic brake sensors i haven't found any at PSW. Could you link to something? ... In connection to this does anyone have any tips regarding the walk assist - when holding "i" - not working? Can it be anything else than the button on the handlebar itself? As i mentioned i have use...

Re: TSDZ2 mid drive -- Flexible OpenSource firmware for TongSheng TSDZ2 mid drive motor

I learned a lesson the hard way today. Could not get newly flashed LCD3 displays to initialize. They just powered up with all crystals on. After trying everything I could think of over about 3 hours time I discovered that the display will not complete its initialization with a brake sensor circuit c...

Re: TSDZ2 mid drive -- Flexible OpenSource firmware for TongSheng TSDZ2 mid drive motor

Hey Gals, I faced some hurdles programming the open source software to the motor. LCD was flawless following the instructions on the wiki. But flashing the motor shows several errors and only with every like 10th try I was able to read the option bytes. I use a ST-LINK clone and short wires. The so...

Re: TSDZ2 mid drive -- Flexible OpenSource firmware for TongSheng TSDZ2 mid drive motor

850C LCD I am happy, although I did burn a 850C LCD and an USB port of my computer. I was blocked on this firmware because I was missing communication packages and the display data was hanging/blocking but now it is now more. I had to rewrite a lot of things to get it working. There is still more p...

Will this firmware work with TSDZ2 coaster brake version ?
and if will this need any specific configuration ?
Not yet. However, this is being addressed. There is a lot of resistance pedaling backward in the current version that hopefully will be fixed soon. Watch this forum for updates.

If I were to connect the stlink v2 directly to the tsdz2 motor wires (8 wire version), which colors do I need to match up?

Ok, we tested the coaster brake in assist level 0. It had heavy resistance pedaling backward similar to the other assist levels. I do not have the bike in the shop but will have it tomorrow and will run more tests for PWM and torque sensor readings pedaling backward. Let me know if you need me to t...

Re: Wayne’s Dengfu Carbon Fibre FS 27.5” with Bafang M600 (throttle also)

I got some info on programming the M600. It did not come from Las Vega, but China sales. Apparently, Bafang has moved on from the UART protocol used on the BBSxx and Ultra drives. Like all European mid-drive motor manufacturers, they have now standardized on CAN Bus. It uses a broadcast, multi-node ...

I noticed there are CDB adapters, would any 50t CDN work and can the belt be reused?
I believe the Gates goes on a 130BCD spyder. Get one of those for the TSDZ2 and it might just all work with the same belt and cog. If you do it, keep us posted. Looks pretty sweet!
