using a CY8C28413-24

I have 1 uart added

Want to make P1.5 RX pin, P1.7 TX pin.

Designer version 5.4 does not want to make this connection..so why not?

Hello, I am interfacing with a 16-port GPIO expander using SPI on the PSOC5. I am using a Master SPI and am able to program the GPIO expander using the Write function of the SPI module. But know I would like to read some of the registers in the GPIO expander. I need some help with the programming for the SPI Master read. Is anyone has some examples on doing a read please share them with me.

Thank you very much,

Joe

HI all,

In 059 kit have only one uart?

12.6 and 12.7 ?

Is there any another pin is assigned for Rx Tx ?

Hi,

I was running into performance issues on one of my slower ISRs (1ms).  I started commenting out some of the newer status checks and I noticed that when the DieTemp block was disabled, my problems disappeared.

All I did was call

// read out temperature in Celsius

temp = DieTemp_Query(&device.MCU_temp);

if(temp == CYRET_SUCCESS)

{

    DieTemp_GetTemp(&device.MCU_temp);

}

else if(temp != CYRET_STARTED)

{

    DieTemp_Start();

}

for reference "device" is a data structure for telemetry and "MCU_temp" is a uint16 within that structure.

That block of code was taking on average about 1.8ms.  Why is this so slow and is there an efficient way to non-block poll the Die Temperature in real time? 

Let me know if I did something silly as always...

Please see attached the File.

About resources of UDB, when using Counter.

Before using Counter, the UDB resources looks like enough resource.

But adding counter, there happend Error that looked like coused by UDB resource shortage.

The Error Message is below.

-----

Error: plm.M0046: E2071: Unable to pack the design into 24 UDBs. See the Digital Placement section of the report file

for details. For additional assistance, see the Mapper, Placer, Router section in the PSoC Creator help.

Error: plm.M0046: E2055: An error occurred during placement of the design.

Error: plm.M0046: "C:¥Program Files (x86)¥Cypress¥PSoC Creator¥4.2¥PSoC Creator¥bin/sjplacer.exe" failed

------

It seems that resources can still afford to add resources (data sheets) used for counters, but they will run out.
Why is that?
