PSoC™ 5, 3 & 1 Forum Discussions
I'm trying to implement a VME interface using a PSoC devices, but there are some things I would know.
- How a status and controll register are accessed from uC ?
- For example, If I use two 8bit status registers for reading a 16bit data bus, using the cortex-M3, the reading will be performed contemporarily or it needs two or more clock intervals?
- How they are mapped on PSoC?
- What type of internal bus they use?
- Could I associate the same variable at two or more status or controll registers?
- There is a way to choose to use the FIFO registers contained in the UDBs or it is the IDE that assign the internal resources?
Thanks in advance
Show LessHello
Im doing big project on my psoc 3 and I'm wondering wher can I find size of free space of PLD matrix in Psoc Creator.
Is thare option to check it anyway?
Thanks
New to PSoC3?
If you have not looked at PSoC 3 before, take a look at AN54181 Getting Started with PSoC3 Design Project. It will get you started quickly on a very simple project. And it will also link you to other documentation if you are looking for more information.
Are you wondering if is it possible to interface temperature sensors like thermocouple, RTD, Thermistor with PSoC3? Are you wondering how to go about it and about the accuracy and effort required. The answer to these questions is explained very well in the following article:
Cypress will be bringing out a kit to evaluate all the above mentioned temperature sensor. It will be available in Q2, 2011. The following App Notes describe temperature measurement usign diode and Thermistor respectively:
AN60590 - PSoC® 3 / PSoC 5 - Temperature Measurement Using Diode
PSoC® 3 and PSoC 5 Temperature Measurement with Thermistor - AN66477

Show LessMy I2C communications need to be pulled up to 3.3V, but I don't know what size pull up resistor I should be using. I've read other forum posts that suggest 2.7k ohm or 4.7k ohm, but that only seem to allow the high to be at 3.3V and the low to be at 3.0V. Is that normal? I'm using a CY8C27443 PSoC1 and the bus capacitance is 30pF if that helps at all.
If I could get an answer ASAP it would be greatly appreciated.

Show LessI was trying to use the shift register of PSOC creator 1.0 and I wanted to know what is the easiest possible way of knowing by hardware when the parallel value loaded in the shift register has been shifted out completely.
Thank You
Show LessI'm a newbie in PSoC and c programming. Currently I'm using the CY3210-PSoC1Eval to develop a simple system which requires to store some values from ADC into the SD card, probably to be saved in .txt file. What I know is the PSoC Designer has already taken out the SD module and the alternative solution is to use the SPI module, but I'm stuck here...
Is there any example or tutorial available for this application? Thank you very much!
Show LessGreetings,
I would like to use the a Timer in Psoc creator to determine the period of a signal and to deduce from it its frequency. I know I can use a frequency counter with a PWM but I do not want to use this technique. I would like to have a very fast update on my frequency measurement in order to be implemented in a control law.
I have attached a very simple project where I try to make sense of the Timer function. I have tried to read the signal Period using the ReadPeriod() function but it always display 0xFFFF no matter what. I have tried most of the other functions and I cannot make much sense of them, I have read the documentation and I thought this ReadPeriod() was the way to go. Can somebody help me seting up the Timer correctly and tell me how to read the period of the signal?
Thanks a lot,
Ben
Show LessHi,
I just cannot seem to understand how the Counter component works. It seems simple, and yet my design doesn't work.
I have an input pin connected to a signal which is low most of the time, but occasionally sees high pulses lasting a few tens of milliseconds. These occur at random intervals.
What I would like is to keep a count of the total high time of this signal, and generate an interrupt when it passes some threshold.
I have attached an image of my schematic. The counter is configured as a UDB down counter, period 200, interrupt on TC.
Please set me straight.
