IIC(Inter-Integrated Circuit)总线是一种由PHILIPS公司开发的两线式串行总线,用于连接微控制器及其外围设备。I2C总线产生于在80年代,最初为音频和视频设备开发,如今主要在服务器管理中使用,其中包括单个组件状态的通信。例如管理员可对各个组件进行查询,以管理系统的配置或掌握组件的功能状态,如电源和系统风扇。可随时监...
(3 bits), and the R/W bit which is a logic low is placed onto the bus by the master transmitter. This indicates to the addressed slave receiver that a byte with a word address will follow after it has generated an acknowledge bit during the ninth clock cycle. Therefore the next byte ...

图18.4是初始化的理想时序图,其中CLOCK1为 -210°的系统时钟,CLOCK2为SDRAM的时钟。rCMD为CKE,CS,RAS,CAS还有WE等命令。rA为A0~A12,rBA为BA0~BA1等地址信号。初始化过程如下所示: l T0,满足100us; l T1,发送PR命令,拉高所有rA与rBA。 l T1半周期,SDRAM读取。
My first version runs at 400MHz input clock producing ~195kHz multiphase PWM, and the Verilig version fails at 100Mhz input clock. Did I miss something? I use Cyclon 10 LP family. Thanks for helping. With best regards Gerhard Translate0...
