PSoC™ 5, 3 & 1 Forum Discussions

Hi,

 What is now the official version of silicon availability of PSoC5?

I know there is a few of them on evaluation kits, but the question is about the IC available to the masses.

I was promised samples about 6 months ago and nothing happened (had to use smth. else for the project)

The contest is a good way to make PSoC5 popular by showing what you can do with it, but if there is no silicon

what is the point of it?

Regards

My project is to use a microcontroller in a device which can be controlled by the PC(windows) through usb, so the first requirement is to select a microcontroller which supports usb and based on 8051 core (PSoC-3). Also I have to write the .exe file (on PC) which will communicate with the microcontroller,recommended to use c++ or c as the programming language. So my question if you can help me with a ready made driver that can be used on the pc or integrated in the software to support communication with PSoC-3.I need also application notes on how to configure the PSoC-3 USB driver to be connected to the PC.
Thanks in advance

 

Hey guys,

 I'm master's student and would like to join in contest, however I've few questions:

1. Until what time do I need to have design assets ready? or is it that I can submit it anytime until May?

2. Can I work in team with one of my friend?

3. Any general getting started you think is helpful

Thanks

Hi,

I may be interested in participating in the challenge, but need some clarification on the resources.

If one makes it to the stage to receive a dev kit, what chip will it be, how much GPIO will the dev kit provide?

The design I anticpate may require up to 24 digital I/O pins, plus 8 Analog input pins, a couple of DAC outputs, and maybe a couple of event timer input pins. Maybe even another 13 I/O for a graphics LCD display. Will the dev kit be adequate to fulfill this?

Thanks,

Tony

 Hi all,

I am trying to read the analog value output from a LM35 temperature sensor. I am reading the value received with the ADC, but I constantly get an offset of almost 1mV. This is problematic for me, since I am evaluating the PSoC devices for use in future products.

I am using a single ended delta sigma ADC with the following settings:

Conversion mode: Multi sample

Resolution: 16 bits

Conversion rate: 10 000 SPS

Input range: Vssa to Vdda (even though changing the range didn't do anything to my faulty reading)

Buffer gain: 1

Buffer mode: Rail to Rail

Reference: 3.2910V (As measured at Vdda)

I saw a demo where they got uV precision. Is it possible to get this kind of precision with this dev kit? How can I ensure precision when I produce my own PCBs?

Your help is appreciated.

 Hi,

I've been experimenting with a PSoC 3 'FirstTouch' eval kit. So far I am very pleased with it.

I am beginning to think about a serious application for a PSoC 3 chip, and thought I would circulate a few ideas here and see what the rest of the community think of it.

I'd like to build a universal IR (Infrared) receiver and decoder. One which can decode just about any common infra red remote control signal. The front end would be Vishay or Sharp Infrared receivers which demodulate the 36/38KHz signal.

I think I'd connect the output of the IR Receiver to a digital input pin.

So what would be best next? Can I implement an IR Signal decoder in hardware? Or should I simply generate an interrupt on the falling edge of the signal, then decode it all in software?

I've already done this several times in various projects, but using traditional micro-processors and doing it all in software. Mainly I just count deltas (the time the signal stays hi or low) and compare against a look up table, with a certain amount of jitter built in. 

However in this new approach I wonder if it's possible to actually decode the IR signal and extract the control codes - preferably in hardware, or a combination of hardware/software.  Any thoughts?

I already understand how to decode IR signals such as RC-5, RC-6 and so on, so I don't need references to 'understanding ir' - I'm more looking for any insight on the best approach to take to doing this on PSoC.

What would be best? A simple digital Input Pin, and ISR and software counters? Or some kind of digital input connected to a timer and shift register? How would that handle the preamble, and how could I detect different encoding schemes?
