PSoC™ 5, 3 & 1 Forum Discussions
PSoC 1 has the unique capability of 'Dynamic Reconfiguration'. It means that a single resource can be used to perform multiple function. We can consider a cold drink vending machine for example. Majority of the time it has to perform as a vending machine chucking out cans and collecting money. But at night, for some time it has to act as a communication device to send various details such as inventory status, sales data etc. For any other microcontroller seperate resources are required for the two jobs. But in PSoC 1, a single resource can do both the jobs using Dynamic Reconfiguration. This enables the user to use a lower end part having lesser resources thus achieving cost savings. More information can be found in application note AN2104

Show LessI need help designing a power supply for a portable medical research device that uses PSoC 3. My problem is designing a configuration for multiple voltages with pcb size and power efficiency in mind. I need ~3.3 V, ~ +/- 1.5 V, and +/- 20 V.
Below I’ve listed device info and estimated current consumption of both the analog and digital components.
Device Info: My device will be worn by small rodents and used to (1) amplify low-voltage and low frequency (< 15 kHz) analog signals, (2) output 100uA@20V constant current pulses, and (3) communicate with PC via BT. This device will be small (2’x2’ double sided pcb) and light weight. Thus, efficiency and pcb footprint are extremely important. Component cost isn’t much of a concern.
Digital Components:
- PSoC 3: 10 mA @ 3.3 V (Supply Range: 1.7 - 5.0 V )
- RN-42 Bluetooth Module: 15 mA @ 3.3V (Supply Range: 3.0 - 3.6 V, peak current 50mA)
Analog Components: All analog components use dual power supplies (+/-).
- Section A: 1mA @ +/- 1.5 V (<1% duty cycle, Supply Range: 1.0 - 3.3 V)
- Section B: 2mA @ +/- 20.0 V (1% duty cycle)
Battery: I was hoping to use a 3.6 V LiPo battery unless there is a more appropriate battery or source voltage.
Questions: Where and how should I use LDO, switching, or linear regulators together for this application? What’s the best way to get the +/- 20 V? Should I adjust any component supply voltages for higher efficiency? ... etc...? Any help would be tremendously appreciated.

Hi!!
I got a problem with the SmartSense i´m use Proximity Sensor in the chip cy8c21334B-24PVXI, when i near to the cable in the proximity sensor should ligth a LED but this not happen i do know why :S I´m use too the cy8c21345-24sxi and in this chip work perfectly and I use the SmartSense also so if sombody can helpe i´ll be grateful
hi developers,
for one of my applications i need to implement an analog integrator using an On-chip PSoC block. can any of the existing analog modules can be configured in such a way that i can access all the standard op amp pins i.e. the inverting terminal,the non-inverting terminal and the output unhindered by other components.
Show LessHello All
There are a couple of new interesting features in PSoC Designer 5.3 such as
- Auto-Routing
- Upgraded Device Catalog
- Cleaner User Module customization
It also has eight new User Modules.
For details, please refer to the link http://www.cypress.com/?rID=41083
Do download the latest PSoC Designer, use these features and let us know your inputs.
Thanks

Show LessHello,
The use of " User modules" in "Designer" is comfortable. Unfortunately, these modules do not allow to use all the features of the material.
Example 1: "Timer16" does not allow to use the mode "multi-shot".
Example 2: "SwitchCapConfig" does not allow to configure the entry "Analog Modulator Interface ( Mod Bits)"
What is the best way of adding these configuration?
"Custom User Modules" seems planned for it but I do not find documentation or example of use.

So I try to count time using a CY8C24123A
I use an 8bit counter running on 32 khz and make it interrupt at terminal count. Every time it interrupts, I add 1 to an integer, 1 is equal to 0,008s or 8ms.
32000/256=125
1s/125=0,008
But if I try and count 60 seconds, it will count 63 seconds. And the longer I count, the more wrong it will get. 90 will be 94,5
I cant figure out where I can have a problem. The counter is running sync with the processor.
