In stop mode all GPIO pins will be frozen. Can I change the pin status, after waking up from stop mode by a wake up reset?

 Unlike the LEDs present in CY8CKIT-030 and CY8CKIT-050, in PSoC 4 Pioneer kit , 'zero' has to be written to the LED pins inorder to turn on the LED. In Pioneer kit the positive terminal of the LEDs are connected to ground and the negative terminal is going to the respective pins.

Hi All,

For your information, the Die Temperature component's API in PSoC4 (DieTemp_CountsTo_Celsius()) might return incorrect value in few of our devices. This problem has been rectified in the devices which are currently in production.

If you too experience the same problem, you do have a work-around, where you need to change the statement "offsetReg = (int16)DieTemp_SAR_TEMP_OFFSET_REG; " in DieTemp.c file to "offsetReg=0x65B4;".

Hi everybody,

Another difficult question...

Does the PSOC4 support LIN bus? PSOC Creator does not have the LIN component for the PSOC4 device, but the datasheet states:

When you add a UART object then you can select between IrDA and Smartcard, but there is no LIN either.

PSOC5/PSOC5LP has a very nice LIN component with a packet builder. Will this be implemented for the PSOC4?

Thank you,
Errol.

This is a full-feature UART operating at up to 1 Mbps. It supports automotive single-wire interface (LIN), infrared interface (IrDA), and SmartCard (ISO7816) protocols, all of which are minor variants of the basic UART protocol.

 With this diagram, it is possible to quickly figure out what is possible on the PSoC4 Analog subsystem.

 Hi, 

PSoC4's TCPWM_P4 Timer/Counter component is declared in the datasheet to work with maximum clock frequency 48 MHz. 

In my experiments I am not capable to use the Timer/Counter "clock" at higher frequency that HFCLK/2 which is in my case 20 MHz. My PSoC4 in CY8CKIT-042 runs from External quartz 40 MHz oscillator (TCXO).

The Timer/Counter "count" frequency for proper operation need to be < HFCLK/4. 

Where is my problem? How is defined the 48 MHz limit in the datasheet.

Viktor

 Hi, 

in the artickle "Using Clocks with PSoC 4" http://www.cypress.com/?id=2401 Brad Budlong has described how to convert the PSoC4 clock signal to a data signal. 

My question is "How to simulate the PSoC4 clock with program tools". Using the Control_Reg for this purpose is possible on PSoC 5LP (because the Control_Reg outpus are data) but not on PSoC4. In other words how to convert  "data to clocks" on the PSoC4 platform.

Regards,

Viktor

Hi all

This is my first project for Psoc4 Pioneer Kit and sparkfun Nokia 6100 shield.
