我使用了hid 标准鼠标的范例,范例的内容大致是将0x81 IN端点设置成INT模式,然后通过感应GPIO的按下,模拟鼠标左键的按下,从而让EP IN端点输入了大量的数据(应该是坐标数据)
我希望更改成UART输入,然后通过某一个EP IN端点输出类似这种数据。请问者能够实现吗?此外,我更改下列图片进入打印报告函数的条件,更改恒为1,但是它并没有打印报告出来,这是怎么回事呢?难道是在初始化的时候已经绑定了只有在认定的GPIO引脚触发的时候,才能调用此回调函数,从而打印报告吗?

你好,在示例F:\FX3_SDK_WORK\EZ-USB FX3 SDK\1.3\firmware\slavefifo_examples\slfifoasync5bit中,我将EP15设置为手动模式,但是在创建输出数组的时候Debug遇到了CY_U3P_ERROR_TIMEOUT返回
我应该如何做才能够成功创建输出数组,然后使用CyU3PDmaChannelCommitBuffer()函数将我所需要的数据传输出去?
感谢您的回复
我非常迫切的想知道答案,这已经困扰了我2天了。

CYUSB3314 hub USB2.0 conformance test, I saw online that I need to send a set port feature request, I would like to ask if there is a way to do it? Is it possible to set the registers to realize it, or do I have to use the PID/VID board to do it?

Show LessI would like to ask what would cause this error?
What I have in my code is to create an array of outputs on the INT side of EP0 in the UART callback function, and then push the data from inside the UART out through the IN side of EP0. Now this build output array reports an error

What's going on here? Anyone know?

Show LessIn the code, I observed that endpoint in usb has 15 endpoints and one particular endpoint_0 is bidirectional.
One of the things I'd like to ask is, since endpoint_0 communication in USB requires handshake interaction, is there a document that explicitly states that it requires handshake?
Secondly, I would like to ask if my other endpoints need to push out the received data directly to the host side without handshaking, how should I do that?
Nowadays I am now looking at the example, which is using OUT and IN of the endpoint_1 port for dma experiments, where the data is sent out through the OUT side, and then the data is carried to the other end of the pipe through the internal thread, and then the data is read out from the other end of the pipe again through the transfer data-in in the center tool. Nowadays I don't want to push the data out directly through the center tool. Is there a way to do this?
Or is there a corresponding function in the API library?

Show LessHi support,
I am thinking of configuring the CYUSB3304-68LTXC using an external I2C EEPROM. (MODE_SEL[1:0]=2’b01)
At that time, the polarity of POWER_EN seems to be determined by the EEPROM data, so I am curious about what happens when RESETN=L.
What is the polarity of POWER_EN when RESETN=L?
Best regards,
Koki
Show LessI need to observe the USB 3.2 waveform transmitted from the upstream port. To do this, I would like to put the upstream port into USB compliance test mode.
Can you help me obtain information on how to place this device into compliance test mode?
Show LessHello Support,
Thank you for your usual support.
I have a question of HX3.
If the RESETN input is switched to L/H while the CYUSB3304-68LTXC is powered on, is it possible to control the POWER_EN terminal in conjunction?
For example, when the RESETN input is L, can POWER_EN=L, and when the RESETN input is H, can POWER_EN=H?
Best regards,
Koki
Show LessHello Support,
Thank you for your ususal support.
I have a question of HX3.
If the RESETN input is set to L while the CYUSB3304-68LTXC is powered on, will all USB ports on the DS side be disabled?
Also, do you know how much power it will consume in this case? (Approximate is fine)
best regards,
Koki
Show LessHi everybody,
I am currently searching for the land pattern of the reference CY7C65631-56LTXI. It is a QFN 8x8 with 56 pins. Do you have that? A document or an application note, for example?
Thank you in advance.
