PSoC™ 4 Forum Discussions

PSoC4a will  be coming in 28pin SSOP!

Will it be available in 28pin dip to upgrade my DIP CY8C29466 designs?

How to enable PSoC4 in Creator 2.2?

For PSoC 4, we do not have a Vref Component. So you cannot directly connect any internal voltage as a comparator input. But an internal IDAC is available. This can be routed to LPCOMP via AMUXBUS. For this IDAC has to be connected to a pin with a resistor to ground. (IDAC connected to AMUXBUS, AMUXBUS connected to LPCOMP).

A very interesting feature for PSOC4, just wondering what application could be used beside the UART that's being mentioned.

 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.
