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

Can you elaborate a bit more if you have the time? I would like to know the correct settings for a 36v motor (and 48v battery). I hope you understand on the comments and variable names: void calc_foc_angle (void) { uint16_t ui16_temp; uint32_t ui32_temp; uint16_t ui16_e_phase_voltage; uint32_t ui32...

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

@casainho: I've just created a PR for you which fixes the makefile for Windows. Yes, I've started developing :D Mainly for changing some configuration for now. Btw: what's the difference (in configuration) between the 36v and 48v hex files? I can't seem to really find this in the source... Has some...

Re: New "TSDZ2 Torque Sensor Central Motor"

I've decided to go all-in and install the opensource firmware and LCD3, wow! I've just finished my test ride using this firmware. Changed the configuration a bit to prevent an accidental run away because I'm not using ebrakes. Left all other settings default. Compiled the firmware. After the program...

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

@casainho Nice work! I can't wait to try it... I don't have the Tongsheng brakes nor the hidden brake wire (whatever it is called) can I use the opensource firmware? Or do you advice against it? I'm prepared to experiment but I wouldn't like the bike to run away from me :D The firmware can now be c...

Re: New "TSDZ2 Torque Sensor Central Motor"

Alright, I've tried almost all your suggestions and it's not helping unfortunately. I've also reconnected the connectors in the motor, amongst them the Hall sensor cable. Could it be that programming the data memory (changing values) of the 36v controller to 48v simply doesn't work at all? Like some...

Yes Opensource displays the cadence and no the amps does not work on the original display.
My friend was able to make a cadence meter use an old speedo and mounting the magnet to his cranks
Thanks. I do have a Garmin device with cadence sensor. Will install and try this tonight if I find the time.

Re: New "TSDZ2 Torque Sensor Central Motor"

I believe it does work. Currently I don't have a cadence sensor mounted but will do that soon. Does the opensource firmware display cadence as well? It feels like the motor assists easily up to around 90-100 RPM, will get back to this with real figures soon. You could be right in that I experience s...

Re: New "TSDZ2 Torque Sensor Central Motor"

What do you exactly mean with overvolting from 36v to 48v? if you are running a higher voltage it can cut-off the motor. so maybe try to drain you battery a little bit more and see if it works? I'm using a 48v battery with a 36v motor to get assist while having higher cadence. Because I'm usually a...

Re: New "TSDZ2 Torque Sensor Central Motor"

Thanks guys. Where is this board located? I didn't open up the casing yet. When the hall sensor is failing, how can it be that it works perfect in the first two assist levels? Also, overvolting from 36V to 48V isn't causing this issue is it? I have programmed the data memory accordingly.

Re: New "TSDZ2 Torque Sensor Central Motor"

Thanks! That could be the case, but the display says that the battery is 100% full and the LED indicators on the battery casing indicates that the battery is around 75%? Don't know if those measurements can be trusted... I didn't fully charge the battery yet since I've received it.

Re: New "TSDZ2 Torque Sensor Central Motor"

Yesterday I've quickly mounted (sort of :P ) all the parts to my bike. The good news is that the 36V motor works with the 48V battery, the bad news is that the speed sensor reading is all over the place and often just shows 99.9 km/h. I'm certain that I wasn't flying :D. Should I increase the dista...

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

Hi guys, I'm an avid cyclist and a fellow software developer myself. Last week I've received my TSDZ2 and the LCD3 as well. I didn't mount the motor yet, have received the battery only yesterday and am still missing the battery connectors. However, I've made the programming cable and have updated th...
