WebSTM32F051 has several timers for you to play with including TIM1, TIM2, TIM3, TIM6, TIM14, TIM15, TIM16, and TIM17. Basically, the timer and counter are just different from the input clock signal. For the timer, the clock source is an internal clock that is generated from the external crystal internal RC circuit of the STM32F0 Discovery. Web13 jun. 2024 · 1 I am trying to make my own driver for WS2812 LEDs with a timer generated PWM and a circular DMA buffer for conserving memory. I managed to get the right timings, however, looking at the signal with a logic analyzer, I notice that two main things go wrong: When, for example, 72 bits are supposed to be sent, only 27 bits are sent.
