Hi everyone,

Could I use the DMA controller to perform a reading on a MASTER SPI?

Setting the source address of the DMA channel and TD as the pointer to the RX data buffer of the spi, I do a reading of the buffer contents, while I need to perform a new reading.

There is a way to do this ?

Thanks in advance for any suggestion

Hello,

I have a problem with programming CY8C3866AXI-040ES2 on my own pcb board.

When i go to program menu (ctrl + f5), i can see that my device is seen, but ther is also message: "Avaible fo use Unacquired."

When i go with pointer on device name, it shows also massage: "Unable to read memory, Debug anable is not set, Click Port Acquire to to reset the chip and enale debug. When I do it, nothing is happening, still the same error."

And last think, when i double click on device on this programing menu i've got: "Unable to read the silicon revision for target device 'unknown target'. Click Port Acquire to reset the chip."

I have no idea what can I do now.

Please help,

Thanks

Hello:

I have same question about the USB function setting in my project ,and the details are as follow:

1.In my project, i want to use the USB component to communicate between my DVK and WIN7 PC,

    dunring the running time,the DVK sends message to PC,and then PC deals with message, after that

    PC display the result(such as plot point or line) in MS paint!

2.And the attached file describes the problem more detailed, and the project can plot line continually!

3.Thanks for you kindly reply!

When I switch the device from CY8C3866LTI-030ES2 to CY8C3866LTI-030, the creator generates a new warning:

What does this mean and how to fix it? Thanks

Hi,

I'm trying to modify the CY3240 firmware (through PSoC Designer) so that it retains all its bridge functionality but can also use some of the I/O pins on the dev board to read voltages through its internal ADC. Ideally, the dev board would function as normal, routing USB commands to the i2c bus, but would also be able to intercept certain packets that tell it to access an I/O port.

Anyone have experience with this (e.g. sample code)?
