USB low-full-high speed peripherals Forum Discussions
I'm trying to use FX3 as programator for FPGA. First of all, code (AN84868) for project is not available on Infineon web page: Link .
Second when I try program FX3 with FPGA Configuration Utility and pre build FX3 code "ConfigFpgaSlaveFifoSync" with Debug version all works fine. Code is normally uploaded of FX3 device. With FPGA Configuration Utility I can select bitstream. The problem happen if I try to build FX3 code in EZ Suite (no code change). Build is successfully. But when I upload build image (debug or release) with FPGA Configuration Utility on FX3 device I lose connection with device.
FPGA Configuration Utility after programming:
I'm using Ztex 2.18 board with CYUSB3035-BZXI.
Does anyone have any idea what is problem?
I would be gratefully thankful for any advice. Kind regards.Show Less
Is the power domain of the two pins "USBDP" and "USBDM" VCCIO?
Vih and Vil are defined with reference to Vccio. Can USBDP/DM follow these specifications?
I would like to know if it is possible to input up to 3.6V, which is the USB2.0 full speed standard. And I also would like to know if Vih and Vil do not change even if 3.3V is applied to VCC.
we are Infineon colleagues and searching for a USB 2.0 to microcontroller UART converter.
Because we want to use it for a customer design board.
At the moment we are using FTDI TTL-234X-5V-WE. We would prefer to use an Infineon equivalent.
Can you help us out and propose a device?
Maybe a small explanation about the different devices Infineon provides? (Product Selection Guide style...)
Hello. I'm using the CY7C65211 in our design as a USB to SPI bridge. I have two questions about the operation of this device...
- What is the difference between programming a configuration into the flash of the CY7C65211, versus calling CySetSpiConfig in the software API? For settings to take effect, do the settings need to be applied to the flash config? or via the software API? Or both? Does one override the other?
- What is the proper way to generate a SPI transaction that consists of 24 bits (4 words of 6 bits each)? How should the data buffer passed to CySpiReadWrite be organized? Do the words need to be byte aligned in any particular way? Do I simply pack the 24 bits into 3 bytes and set the transaction length to 3 bytes in the write buffer?
Thank youShow Less
We have some question on X-ray result. Why are they had different image? Are they normal? Please see attached photo.
I am trying to commit packets using inpktend .
Is there anything in particular that I need to take care of apart from FIFOADR[1:0] pins select. I want to further transfer the received packets to the host.
I have an external device which has two signals , one is start of frame and , which I use as an interrupt to the FX2lp and a data enable signal which i want to write to fx2lp using SLWR pin. Basically i use fx2lp in slave FIFO mode. Now my target is that when I receive a falling edge interrupt and the SLWR goes low at the same time , I must start reading the data. I use EP2 buffer to get the data.
I observe that i cant get any data after connecting the device and fx2lp.
I am attaching the code below.
I am using a manual in transfer method using INPKTEND register to transfer the data and have a 16 bit data stream.
I am following this example thread for some clues Interfacing FX2LP™ with Image Sensor – KBA95736 - Infineon Developer Community
kindly help me with this issue. Do i miss something here?Show Less
1.使用USB-Serial Configuration Utility配置参数，显示program succed，但是使用TEST Utility时，读写测试数据，显示“write fail”和“read fail”，驱动已配置，device也被配置为I2C，请问可能是哪些问题？
