New version released.
Everything should be updated, Android App, ESP32 and Controller.
The files are on Github: https://github.com/TSDZ2-ESP32/TSDZ2-ES ... master/bin
- Android: TSDZ2_ESP32v2.1.10.apk
- ESP32: TSDZ2-ESP32-Mainv1.1.8.zip
- STM8: TSDZ2-v14.zip
This version improves the motor efficiency under high loads.
In particular, the code that calculates the "Advance Angle" (FOC angle) has changed.
The old algorithm gave an underestimated value. Now the algorithm has changed and the value is calculated once every electrical revolution within the fast PWM interrupt.
I did some tests on a reference climb with the motor constantly at 400/450Watt and with the new version the motor warms up much less.
After the update it is necessary to change the motor configuration.
There is a new parameter "FOC angle multipl." which replaces the "motor inductance" parameter.
In the Android app select: "Bike Configuration" -> System and select 36V or 48V according to your motor.
The parameter can also be entered manually in the range 0-50. If you want to experiment you can increase/decrease by 3 or 4 each time to see if you get further improvements.
As you can see from the screenshot I also added the possibility to disable the "Field Weakening"
The update disables the "Torque Offset Fix", and whoever had it enabled will have to enable it again after the update.
