Hi all, I am somewhat new to embedded design and have a few questions. I'm want to be able to read/write to a USB thumbdrive from the Xilinx ML-403 board (with a Cypress CY7C67300 USB Chip). Will I need to write up the device driver for the ML-403 or is the protocol already on there. I guess the main thing I'm trying to figure out is the best way to begin to go about this problem. Any tak...

I wrote a multi-processor serial bus protocol. It was to connect several F340 as slaves to one Cypress FX2LP as master. The master sent out a command byte with the ninth bit set which alerted the slaves to what was happening next. Interested slaves then participated in various ways (but only one sending, of course). It was unreliable. Stripped down to one master and one slave, it ...

I've purchased one already made by "Cypress Semiconductor" but it doesn't work. The VID is 04b4 and the PID is 5500. Can anyone suggest a USB to RS232 adapter that does its job perfectly 100% of the time under Microsoft Windows, i.e. it trully behaves exactly just like any other serial port?

As far as I can tell from the specification, the Maxim MAX3100 can lose bytes if the FIFO overflows and the softwarae cannot detect that this has happened. Of course, the software should be quick enough, but real life is full of nasty surprises. The CRC should detect it, but see earlier remark. I have to hook a PIC16F876 to a Cypress 8051 using the debug ports (so no CTS or RTS wires)...

Hi ! I have some mysterious problems with cypress fx2. Sometimes if I make small changes in our firmware things go wrong (mostly the enumeration process failes).

Perhaps anybody has some experience with this kind of problem...

Wanted to try some simple stuff with a PSoC and I've got the large kit from the 2006 World tour, the one with four experiment circuits on there. Looking for schematics the closest I found was CY3209 which is very similar but not 100%, and all part designators are numbered differently. Possibly the "old" kit from 2006 was CY3121 but not sure, there is no info on the board itself. There i...

Hi, I'm trying to read data from I/O port C on the FX2 development board into my computer and then immediately write the received data back onto port E using the CyAPI library. I'd like to be able to run this cycle of data transfer (IOC-> BulkInEndPt-> PC console application-> BulkOutEndPt-> IOE) at a few kHz, but so far I've had no luck. I'm using two 512 byte 4x buffered bulk endpoints. My TD_Pol

Hello all, I working on a Cypress FX2 dev board thats Bulk-Only Mass Storage Compliant. I've looked at the CY4611 example in detail, but it is more limited than I need. I need to implement SCSI protocol at the firmware level, because there is no SCSI compliant device behind it.

I am not sure this is the best group, but it might be close enough. In our current project we use PSoC controllers from Cypress and we access our application by reading and writing variables (by address). To do so we parse the map file on the host to figure out the address of a variable and then send the address to the PSoC. Over time our host code (in Python) became more complex and w...

Are there any cheaper alternatives? Or maybe some software emulators I've overlooked? Could I somehow use the P...
