Version 16

v16

FOC angle parameter bug fix

Version 14

High load motor optimization:

• motor_controller() loop removed
• FOC Angle calculation algorithm changed
• Field Weakening Enable/Disable

Version 13

Version 13

• ADC values Right aligned.
• To avoid overrun errors, ADC buffered values no more readed in ebike_app but in pwm-up interrupt (end of conversion)
• Fixed minor bug in main loop timings
• PWM freq decreased to 18KHz (all values parametrized in main.h)
• Power glitch bug fix (race condition between PWM interrupt and Hall GPIO interrupt)
• FOC angle asin_table optimization (thanks to beemac)
• PWM Dead Time increased from 1us to 1.5us (OEM firmware uses a value of 3us!)

TSDZ2-ESP32 STM8 v11

• Use different Hall counter offset for every Hall state
• Updated low pass filter() function

TSDZ2-ESP32 STM8 v10

• New Motor control algorithm:
  • IRQ based Hall detection
  • Hall counter @ 250KHz
  • Hall Calibration (Angular and Time correction)
  • Hall counter correction based on Hall state
  • Phase adjust step by step
• HW triggered ADC conversion (OC4Ref signal)
• Added calibration mode to riding modes

TSDZ2-ESP32 STM8 v7

v7 - Motor Optimizations:

• TIM1 PWM Freq to 19KHz
• Better rotor interpolation:
  • Double TIM1 IRQ rate
  • Hal sensor detection running at 38KHz
• Updated motor svm_table according to TIM1 PWM freqency and to upper bound of TIM1 counter
• Motor ref speed calculated two times every electr. revol.
• Battery current sampled in the middle of PWM duty cycle (counter = 0)
• Max Field Weakening angle calculated based on motor speed
• Higher Power Assist multiplier resolution (2% insted of 10%)
• ADC Freq. = CPU Freq/3

TSDZ2-ESP32 STM8 v6

• Added Field Weakening
• Various code speed optimizations
• Increased PWM frequency to 20KHz
