PSoC™ 5, 3 & 1 Forum Discussions

I have used sucessfully miniprog3 for I2C data exchange with PC as Master.

BUt when it came to PSOC1 The miniprog3 reads or writes wrong data!

for example :

write 04 01 (addres 4 first byte of 1) is sucessfully acknowledged up to 0B (data) (w 04+ 01+ p) and (w 04+ 0C- p)

write 04 0C up to FF doesn't get acknowledged

speed 100k on both sides, no external pullups resitors(as it was not required with psoc 3)

What is wrong?

I played with P10 and P11 pin configuration from res-pullup to open-drain-low but no success

Because USBFS pins  is behind CY7C68013A-56LFXC CY7C68013A-56LFXC (another chip with hidden firmware)

I guess USBFS functionality cannot be tested on this kit!!!

Am I right?

This is a chapter from latest PSOC Creator Errata:

"11.  CapSense Use of a PRS with the CSD algorithm is not
supported.  PRS configuration should be set to None. This will be corrected in a future release. "

What happened?

Will PRS for CapSENSE be no loner supported?

Hello,

I think that (maybe) there is a bug in the subtraction verilog implementation of 2 variables :     

To visualize the result, simply connect the DA to the outp, and clock the module with a 100kHz, for example…

module bugtest (

);

output [7:0] outp;

input   clk;

//`#start body` -- edit after this line, do not edit this line

reg [7:0] outp;

reg [15:0] offset;

reg [4:0] saw;

always @(posedge clk)

begin

// saw generator

saw <= saw + 1;

// offset

offset <= offset + 1;

// add is OK

outp <= {3'b0, saw} + offset[15:8];

// BUG if sub

// outp <= {3'b0, saw} - offset[15:8];

// corrected sub is OK

// outp <= {3'b0, saw} + ~offset[15:8] + 1;

end

Hi, I'm trying to make an application with visual basic based on USB HID to control my hub. I'm using a CY3271 kit of CYFI. Is it possible? Any help?

Thanks very much
