The filter is a lowpass filter 64 taps (about 5% overshoot)
on the picture we have :
signal3 : 300kHz DMA clock (input and ouput of the filter are DMA)
signal4 : The duration of an ISR program that changes the input value of the filter from -100 to 120 and back, to perform a signed square signal
signal5 : the sign bit of the filter output (bit 7 of HOLDAH register)
CH2 (red analogic curb) : the output of the filter with an offset of 128 ==> 8 bits DAC
We can see that at the end of the rising edge of CH2 (and before descent) the sign bit of the filter is swicthing to negative values generating a bug in the response of the filter.
I want to develop several products based on the FX3, But I can't find any manual reference book on your website. The manual reference book would be one just like the TRM for FX2, which describes suffiiently on every aspects of the chip's usage.
thank you !
Best wish for you all!Show Less
I am new to PSoC and trying to use the EMIF but I cannot find a good documentation for it.
I didn't even found a Component in the Component Catalog to add for EMIF. There is one in the installation folder, called psoc\content\cyprimitives\cyprimitives.cylib\cy_emif_port_v1_0 but it doesn't appear in the Component Catalog.
How do I add this component? Or is there any other way of using EMIF?Show Less
I'm a developer from a small company and I want to get the CYUSB3014 chips and evaluation board to use this super speed controller in the next project. The project is the high speed camera for machine vision application. I've contacted local disti and they've answered that the only large customers could get this prodct. Is there any opportunity to get the things? There are no local Cypress offices available. The coutry is Ruissia.
Thanks in advance!Show Less
We are going to use FX3.0 instead of FX2LP in our design. However, I did not find any sample code for the interrupt endpoint. In our design, we are using an interrupt endpoint to send command to the FX and based on the received command an specific action should take place. For example, configuring an FPGA by using GPIO, ...
I would appreciate it if you could provide me a code sample,
Where can I find CyAPI.lib for borland builder 6.0. In FX3 Programmers Manual: Versions of the .lib file are available for use with Microsoft Visual Studio 2008 and Borland C++ Builder 6.0. But in the CySuiteUSB3 CyAPI.lib for Microsoft Visual Studio only. Can you send me CyAPI.lib for bcb6 by email.Show Less
I try to read a 0 to 2.5V with the ADCINC14, i use the REFMUX for read 8 port, and I use the external ref (P2, P2).
Analog Power : SC On/Ref High
Ref Mux : P2+/-P2
VDD : 5V
P2 : 0V
P2 : to a ref 2.5V
Problem; can't read more than ~15818 counts...
2^14 = 16384
ref 2.5V/16384 = 152.588uV
15818 * 152.588uV = 2.414V <- this is my problem, if the input is 2.5V or greater never read more than this.
Thanks for reading and helping me 🙂Show Less
If I configure the FX3 as 32 bit wide synchronous slave fifo do I still have access to GPIO pins 50 - 57.
Page 33 of the CYUSB3014 data sheet suggests that these pins are assigned to the I2S and UART functions when in 32 bit slave fifo mode. Can these pins be forced to GPIO?
I'm tried to perform a simple bulk transfer with CYconsole, device CY7C68013A.
I did this only with the Cyconsole without any firmware download. It Is correct?
The message from the console is "transfer failed".
When i download bulkloop.hex, after the download, Cyconcole do not detect the "new" device after renumerating; have i to change some drivers or cyusb.sys is correct?
Thanks for the answer.Show Less
