AT32_TMR and DMA Update PWM Duty Cycle Dynamically
●This document takes AT32F403A as an example to introduces how to use AT32 TMR and DMA to update PWM duty cycle dynamically.
●This sample code use TMR4 update event to trigger DMA1 to transmit data to TMR4 channel 2 data register (TMRx_C2DT), so that to dynamically output PWM waveforms with different duty cycles in the TMR4 channel 2 (PB7).
