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

Having runtime variables initialized to a value, not using the EEPROM in any way, minimizing structs and discarding all other instructions needed for the implementation we have today will be the best for programming memory. Again, we actually do not need the EEPROM on the motor controller unless we...

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

Again, this project is to run TSDZ2 with feature rich LCDs like 850C and SW102 Bluetooth. As there are features yet to be implemented that will bring value to users, this will need memory and everything that does not bring value to users of this project, should be removed. Agreed. That what I meant...

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

hm, i still don't get it. The code is already there, why is there a need for another project or somebody to maintain this special scenario? If i get it right, the eeprom is filled with some default variables if the first byte is not "our key". And these variables are loaded at every bootup. As soon...

Re: TongSheng Chainwheel offset - dropped chain

I took the stock adapter, after cutting off the arms, and mated it to a Bafang style offset 42t, the smallest that will fit over the reduction gear housing, by drilling some new holes in the adapter to match the chainring. Is this BBS02 or BBSHD chainring? How big is offset in mm? BBS is 9mm and HD...

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

I noticed ADC torque sensor calibration min value fluctuates +-5 each start.
Is there downside to increase sample count twice, for example, to 32? As I understand each reading is only 10ms.

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

I also start using startup without pedal rotation. Never had problems with safety with bike "running away", only pedals are twitching a bit when resting feet on pedal on traffic lights stop. Startup with only pedal rotation is pretty slow, especially on v0.19.0. I vote not to remove this option. Upd...

Sorry I can't help, but I am looking to purchase some in 175mm. Could you please tell me where you purchased them?
I ordered them from bike-discount or bike24 a while ago. I am from EU, shipping from Germany.

Anyone tried using Shimano Steps FC-E6000 crank arms? I tried 175mm and when I tighten they are not moving freely. Original crank arms fit well. I have 73mm bottom bracket. Thanks.

Re: Tsdz2 firmware open source adapted to vlcd5

Is there a compiled version of this firmware with VLCD6 support ? I’m not a software developer and would like to flash my motor and use the vlcd6. My long term goal is to be able to compile the code myself, but for just now I’d like to download. Thanks. Compiling is just a matter of installing sdcc...

Re: Tsdz2 firmware open source adapted to vlcd5

Hi. I also made fork with VLCD5 / VLCD6 / no display support. Based on OpenSource-EBike-firmware/TSDZ2-Smart-EBike ( casainho , buba , endlesscadence ) and added TSDZ2 VLCD display protocol code ( hurzhurz , marcoq ), no other changes at all. All configs are in config.h . Need to configure manually ...

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

Hi. I dont quite understand how boost works exactly in code or more specifically in what units boost level is measured (should be same factor as assist level?). As I understand assist level is stored x10 value multiplied by pedal power x10 value or pedal torque x10 value (if no cadence rpm) and then...

Re: New "TSDZ2 Torque Sensor Central Motor"

As I understand wiki says there is only 2 different motor versions 36V and 48V. But seller (pswpower) specifically states "Supports up to 54.6V input voltage, can't work on 58.4V input voltage".
Sorry, but just to be sure I can still buy 48V version and flash it to support 52V battery? Thanks.
