首先_spiSettings是配置 _spiSettings(LORA_DEFAULT_SPI_FREQUENCY, MSBFIRST, SPI_MODE0), 默认的SPI频率为: #define LORA_DEFAULT_SPI_FREQUENCY 8E6 // 2278 第二个参数MSBFIRST表示dataOrder,只有两种选项,另一种是LSBFIRST,分别是Most Significant Bit(ADDR[31:0]),和Lest Significant Bit(ADDR[0:31]) ...
// OPTION 1 (recommended) is to use the HARDWARE SPI pins, which are unique // to each board and not reassignable. For Arduino Uno: MOSI = pin 11 and // SCLK = pin 13. This is the fastest mode of operation and is required if ...
艾尔赛Arduino FOC无刷电机驱动板采用3个分立的高低边栅极驱动器和6个NMOS管组成1路BLDC驱动电路,兼容国外开源项目Simple FOC Shield V2.0.4,可直接插入到Arduino NNO开发板作为一个Shiled来使用,并支持多种传感器接口,用户可以使用Arduino环境下的Simple FOC库来控制BLDC无刷电机平稳高精度运行。
Its simulation is lightweight, modeling the Uno’s ATmega328P chip with enough fidelity to catch logic errors, though it skips advanced protocols like I2C or SPI. I’ve used it to debug state machines, like a traffic light controller, when I needed results fast without graphical fluff. Avail...
SPI clock rate of 2.5MHz so we define that here:#defineSPI_TOUCH_FREQUENCY 2500000//The ESP32 has 2 free SPI ports i.e. VSPI and HSPI, the VSPI is the default.//If the VSPI port is in use and pins are not accessible (e.g. TTGO T-Beam)//then uncomment the following line:/...
