您好,
想請問如何設置CC2530(Z-SATCK) Set SPI speed,我在Z-stack sample code 看到如下所示:
/* Set SPI speed to 1 MHz (the values assume system clk of 32MHz)
* Confirm on board that this results in 1MHz spi clk.
*/
baud_exponent = 15;
baud_mantissa = 0;
假設我想要設置更快的spi速度,baud_exponent 和 baud_mantissa 值要怎麼去做設置,有計算的方式或參數嗎? 感謝您
