Hi, I work already for almost a year with the Cypress EZ-USB FX2 chip and I'm having problems to find out features from the GPIF. GPIF is an internal master for the FIFO's, it can control a peripheral, generate wave signals and also respond to externals. As it has some types of configurations, they should be described on the datasheet but there is mostly found examples and specific configurations. I already had success doing Single Byte Read/Writes and also FIFO Read with and without the transaction counter. The problem is that it makes no sense to use the DP(Decision Point) with the transaction counter. I wanna receive a stream of data, which I don't know exactly how long it is. I configured the machine then to wait for a pin to go down and then to stop. To do so I've seen that I can't simply use the AUTOIN option, because with it, it sends always the same ammount of data. As I found difficult to have information about these details on the datasheet, I would like to ask you if anyone have information about it or even experience. I'm not beeing able to solve all these problems alone... Thanks, Raul
