GPIF II Designer 支持CY7C68013A-56pin, FX2LP Back To Back 16bit datebus数据通讯吗?

(1)我修改了官网提供的demo,WORDWIDE = 1

EP2FIFOCFG = 0x00; // allow core to see zero to one transition of auto out bit
SYNCDELAY;
// EP2FIFOCFG = 0x10; // auto out mode, 8 bit data bus
EP2FIFOCFG = 0x11; // auto out mode, 16 bit data bus
SYNCDELAY;
//EP6FIFOCFG = 0x08; // auto in mode, 8 bit data bus
EP6FIFOCFG = 0x09; // auto in mode, 16 bit data bus
SYNCDELAY;

(2)发现主从收发数据不一致,从设备发给主设备512字节,主设备收到两个512字节数据。

GPIF II desgner是FX3用的,CY7C68013需要用GPIF designer。你修改FIFOCFG肯定要修改对应的GPIF状态机
