从CY的数据表中,FIFO的总大小是4K,EP2,EP6可以在传输中以4x512FIFO武装起来。
在我的应用中,传感器直接连接到68013。换句话说,传感器的数据被填充到68013的FIFO中,没有
FPGA或SDRAM。
我的配置在68013如下:
Ap2在4x512FIFO自动中的AutoLeNH= 0x02 AutoLeNLL=0x00
我做了很多测试,我发现当PC的XFER不稳定时,数据会被丢弃。
但是,我发现丢弃的大小不是很大。因此,如果68013的FIFO大于2K(例如4K),则会更好。
所以,我想知道“如何在CY7C68013A中扩展FIFO的数量和大小”。

以下为原文
From CY's datasheet, The total size of FIFO is 4K, and EP2,EP6 can be
ARMed with 4x512 FIFO in Bulk-IN transfer
In my applica
tion, Sensor is connected to 68013 directly. In other word, data of sensor is filled into 68013's FIFO without FPGA or SDRAM.
My configuration in 68013 as following:
EP2 IN 4x512 FIFO Auto-In AUTOLENH=0x02 AUTOLENL=0x00
I've make many test, I found the data will be discarded when PC's xfer is not steady
But, I found the size of discarded is not big. So, if the FIFO of 68013 is bigger than 2K(such as 4K), it will be better.
So, I want to know "How To Extend the number and size of FIFO In CY7C68013A"
