Not able to used 3 protocols(UART, I2C, SPI) Simultaneously on Cy8C4025AZI-S413 Microcontroller

[AsDh_4015406]

Hi All,

Not able to used three Protocols at a time. I got error when used  3 protocol.

Error: mpr.M0143: Too many clocks allocated for SCB components. (App=cydsfit)
Error: mpr.M0014: Resource limit: Maximum number of Serial Communication (SCB) exceeded (max=2, needed=3). (App=cydsfit)
Dependency Generation...
Cleanup...
Error: fit.M0050: The fitter aborted due to errors, please address all errors and rebuild. (App=cydsfit)

In my project,  required three protocol simultaneously.

How can I resolved this error..... Any help will be highly appreciated. 

Thanks & Regards,

AsDh

Hello.

PSoC 4200S family only has 2 SCB blocks (described on front page of datasheet).  So, you can't get 3 SCB blocks out of 4200S device.

PSoC 4200L and 4200M devices have 4 SCB blocks.  They would be better suited to your project.

If you really need to use 4200S device, you could bit-bang a UART function.  You'll have to search for this code or write it yourself.

Good luck with your project.

edit: Here are a couple of references for a software based UART.  You'll need to modify them for your hardware configuration.

There is a software TX UART component in Creator.
There is also an example software RX UART written by Moto.

You'll need to configure these for your hardware design.

Good luck with your project.
