My driver works fine in Windows XP, but fails in Win7. Window shows "This device cannot start.(code 10)".

I use CY7C68013-128AC. My computer has 2 system XP and Win7 ( 32-bit ).

Driver outputs the below result.  After the driver sends SET CONFIGURATION, return from IoCallDriver

USBD is  wrong (c0000001).

Firmware is very simple.

 {           ...............;

        case usb_SET_CONFIGURATION:           

             Configuration =  Xbyte[aSETUPDAT+2];           

             break;       

            EP0CS |= bm7

}

I would really appreciate some hints about this issue. Thanks!

I went through the driver resell process for cyusb3 for win10, and it appears to be installing and working.  Excellent, thank you.   However, the modified driver package that I submitted only included our company's USB devices (VID/PIDs).   I would like to also add a default Cypress VID/PID to our INF so that we can easily program new/blank boards we receive.  From the CyUSB.pdf this seems perfectly fine ?   I wanted to check before submitting another modified package on the microsoft hw dashboard.

Specific questions:

1. Are third parties allowed to add Cypress VID/PIDs to their driver package for resell ?

2. If I can add Cypress VID/PIDs  (or if I need to add our own new VID/PID), do I need to submit this new INF to cypress  or can I just upload another modified driver package to the dashboard (same as initial one)?

2.a.  If I need to submit an INF to cypress first, how would I go about doing that now that technical cases are gone ?

Thanks,

Erik

Hi,

I have an Bulk IN endpoint with Auto-IN enabled that is constantly filled with data from the external master.

After a pause in data transfer I might want to discard the presumably old content of the endpoint buffers before I continue with the new transfer.

What do I have to write in which registers to declare the input buffers empty so that they can accept new data from the external master?

I assume this is an easy and silly question, but I have worked overnight on my previous problem and my brains feel like two soaked loafs of old bread.

Many thanks for any help!

Hello,

Maximum 18 mA is specified as the total power consumption of Vcc and Vccio in the data sheet of CY8C65213.

I want to know the power consumption Vcc and Vccio separately.

Please teach me the power consumption each power-pin.

Thanks,

Hi,

I tried to activate GPIO pins on PortA but to no avail.

My minimalistic firmware is this:

IFCONFIG = 0x03;

SYNCDELAY;

REVCTL = 0x03;

SYNCDELAY;

EP6CFG = 0xE0;

SYNCDELAY;

FIFORESET = 0x80;

SYNCDELAY;

FIFORESET = 0x86;

SYNCDELAY;

FIFORESET = 0x00;

SYNCDELAY;

EP6FIFOCFG = 0x0C;

SYNCDELAY;

PINFLAGSAB = 0x00;

SYNCDELAY;

while (1) {}

Now I want to activate PA1 and PA3 as GPIO outputs and inserted this before the while (1) {}:

OEA=0x0A;

SYNCDELAY;

CLR IOA.1

SYNCDELAY;

CLR IOA.3

SYNCDELAY;

I know, syncdelay is not really required here, but it should not do any harm.

The PA1 and PA3 pins are pulled to VCC by 22kOhm resistors and they stay high despite the GPIO pins being enabled as outputs (0x0A to OEA at SFR 0xB2) and cleared by the CLR commands.

Even if I write 0x00 to 0xB0, which should also set the output pins low, they stay at 3.3V.

What am I doing wrong?

API for the GPIO (CyGetGpioValue()/CySetGpioValue()) does not allow us to change the direction/drive of the GPIO pins on CY7C65211. In our system we may have a number of this USB-I2C bridge device and we want to be able to configure the GPIO direction/configuration individually on each of these bridge devices at least at system initialization. Is it possible achieve this with CY7C65211?

I see that you recommend to use the configuration utility to do so; in other posts. Do you have a Linux utility to do so? Even if there is one, it will be difficult to call it form our application. Can you please add APIs for this purpose?

Hi,

From this discussion FLAGC set to not empty after TD_Init , using the same firmware.

I have a problem with this firmware, reading from EP6 (from external master), greater than 1024 cause the last buffer data to be zero.

Let's say, I need 1050 number of data to read, the first 1024 is okay, but the next data is zero.

Please be inform that external master sends PKTEND.

Thank you for your support.

Best regards,

Livie

Hi,

I tried to build the Streamer example application from the USB Suite 3.4.7 with VS 2017 Community, but I get a lot of errors.

It does not recognize the System::Windows namespaces, expects or misses tons of declarations and so on.

Can anyone point me to a walk through guide for building these examples with VS 2017 Community?

I don't know if they are buildable with any other VS version, because I only have that one.

Thanks in advance

I only use  CY7C63813，didn't  have  SPI chip.Move the track ball.Light pulses into the CY7C63813 by IO pin.

The direction of the motion is calculated by different pulses.The  difficult is  how to calculate the distance???
