簡單來說就是可以透過電腦軟體Max/MSP發送訊號加以控制arduino,如使用Max/MSP來編寫一些基本的視訊互動(電腦視覺)、聲音互動以及使用一些midi controler(usb數位琴鍵等)來進行訊號輸入;另一種方式則由arduino上的感應器將訊號傳給電腦做回饋,好比透過接觸開關或是光敏電阻等來回傳訊號給電腦產生聲響或是影像回饋。 如果你...
// Optional reduced SPI frequency for reading TFT #define SPI_READ_FREQUENCY 20000000 // The XPT2046 requires a lower SPI clock rate of 2.5MHz so we define that here: #define SPI_TOUCH_FREQUENCY 2500000 // The ESP32 has 2 free SPI ports i.e. VSPI and HSPI, the VSPI is the defaul...

PWM分辨率设置为256, 正好对应8bit PCM采样输出的第二部分是TIM3产生的定时中断, 中断的频率正好是8KHz, 每次中断都修改一次PWM的占空比通过调节PWM频率可以调节输出音质, PWM频率越高音质越好(谐振频率越远离音频)通过调 High System 晶振 MEMP_NUM_PBUF一般多大...
The maximum allowed PWM frequency is 50 kHz. A 100 kΩ pull-down resistor on the shield makes this pin default low. 10 Motor 2 PWM 12 FAULT Fault output: The internal pull-up on the Arduino pin connected to the FAULT input should be enabled so when the drivers are functioning normally...

continued from #4 (comment) In the past, I had problems with SimpleFOC due to the limited speed of the encoder readings. The Arduino interrupt handling code has a lot of overhead, made worse by the various processor layers. If the code h...
When it is high, the motor is on. The maximum allowed PWM frequency is 50 kHz. 13 Motor 2 PWM 24 Motor 1 DIR Motor direction input: When DIR is low, motor current flows from output A to output B; when DIR is high, current flows from B to A. 25 Motor 2 DIR...
Speaker impedence must be 4Ω or more.The output signal is a 330KHz PWM square wave with a duty cycle proportional to the audio signal. The inductance of the speaker coil serves as a low-pass filter to average out the high-frequency components. Do not try to use this as a pre-...
The MmlMusicPWM library implements a child class using which you can play single voice music through a piezo speaker connected to an output pin. Installation/Usage The current version can be downloaded as an Arduino library using the Sketch|Library menu. Just add the zipfile library and the ...
