PSoC™ 4 Forum Discussions

Hello,

Is the whole FLASH erased  when used programmer to program HEX file into internal FLASH of PSoC 4 ? Or just part of FLASH(the length of HEX file) will be erased? Thanks.

On the component data sheet, under resources, it lists how many Datapath cells, Macrocells, Statuscells, Control cells, DMA Channels, and Interrupts.

I am trying to find where the list of how many of each of the resources are available for a project, so I can decide the best balance or if a project is even possible.  Which document is it listed in, and where please?

I have a very strange problem with a LCD-Display and I need some help.

My setup is a CY8CKIT-049-42xx with PSoC 4, a HD44780-LCD display with 2x16-characters.

I used the bootloadable-example and added the LCD-Component 2.10 (name LCD) and mapped the output to Port P2.0-6, connected to the display as described in the datasheet.

I checked several times all the cables and tried several options but the strange behaviour stayed.

Here is my code in main, with comments what happens on the display:

What puzzles me is the fact, that it prinzipally seems to work. The character 0-F are printed fine.

But neither PrintString nor PutChar or any other functions seem to work.

Can anybody help? Did I forget so set anything?

Thanks

Hi All

I am working in a direction to build a library project in Creator. I have placed a default UART SCB and a Timer component in my schematic of the library project. I want to configure ISR handlers for both. But I do not know how to declare those ISR handlers because the standard "CY_PROTO_ISR (HandlerName);" format gives an error during compilation. Is there any method to declare and define ISR Handlers in a library project?

Thanks in advance.

Because PSOC4 does not have dma. So it is confuse to write I2S?

1, firstly how can i control the write speed?

2, secondely I just want to write right channel, how to realize it?

See the attached project.

I am trying to read 512 bytes of UART data into a buffer with DMA.  The setup works fine without the DMA - manually transferring the data into the buffer using the 'BREAK' as a signal for a packet start, but the DMA does not transfer any data into the buffer. 

Any ideas of what I did wrong?  This is my first DMA project, any help is appreciated.

Thank you,
Tom
