setSoftPWM (GPIO_PIN_9, o, &dataA) if we want to use the 33 pins available: /* USER CODE Three 16-bit timers, each with up to 4 IC/OC/PWM or pulse counter and quadrature (incremental) encoder input 16-bit, motor control PWM timer with dead-time generation and emergency stop 2 watchdog timers (Independent and Window) SysTick timer 24-bit downcounter Up to 9 communication interfaces Up to 2 x I2 C interfaces (SMBus/PMBus) Note: STM32 cube HAL API can be used with an arduino sketch. ino Part 1: Arduino Nano 33 IoT – Complementary Pulse Width Modulation (PWM) pulses with Dead Time. Each channel can The dead time value and clock period prescaler for Dead Time Unit A and Dead Time Unit B can be selected using this register. Timers are hardware modules that assist CPU to not only generate periodically events, but also do several features in which some are very important to work with external peripheral like Pulse Width Modulation, Pulse Capture. This is a great solution for applications with a lot of H-Bridges.

0 A new dead time compensation method for a pulse width modulation (PWM) inverter is proposed. With these signals, consisting of 2-bit digital word, each leg of the converter can have four states as shown in Fig. The nonlinear voltage distortion invokes serious problems such as current waveform distortion and deterioration of the performance.

Thus, for the accurate compensation of the nonlinearity, the effect of the dead time should be analyzed with Dead time necessitates hardware PWM and the new series of TIVA ARM Cortex M4f micro-controllers fortunately provides us all the necessary hardware to accomplish this. It seems that I couldn't use more than 2 MHz for clock frequency when config the PWM. I 'm not sure if you have come across this issue. TIM1 and TIM8 the advanced timers will not drive output pin, no matter how I configure uni Initialize the IO port as multiplexing function output.

In Dead Time Insertion mode, the rising edges in the complementary PWM outputs, line and line_n, are delayed. Now we will see complimentary or group PWM with dead-time. As it has 72MHz clock rate, its PWM output can have a maximum period of about one millisecond. When the counter value reaches 0, maximum or a compare value defined for each channel, the output value of the channel can be changed. The PWM duty cycle and output polarity can be freely changed according to need.
