PSoC™ 5, 3 & 1 Forum Discussions
Hello,
I'm implementing a design with PSoC3 and I need overvoltage protecion in some of the input stages. More specifically a protection of 100Vdc. Does somebody know whether PSoC3 has any isolation or protection in its input/output pins?
Thank's. Regards.
Show LessHi,
I have been struggling for days, trying to get the UART samples to work on my psoc3 board.
I am now starting to wonder if UART can be used with my CY8CKIT-003 starter kit.
All I am trying to do is, display the accelorometer data (X,Y,orZ) onto my computer via HYPER TERMINAL.
Please help! A sample which works with CY8CKIT-003, would help a lot!
THANKS SOO MUCH!

Show LessHi,
I am trying to preamplify and sample a microphone signal, but I get a lot of noise.
The microphone gives a maximum of about 3mV of signal amplitude. So at the moment I use a single inverting PGA with gain 49 and try to use lowest possible range +/- 256mV of the 16-bit Sigma Delta ADC omitting it's input buffer. The signal to noise ratio of this setup seems to be only about 6 bits.
What is the best method using the internal amplifiers?
Many thanks!

Show LessHello All,
I noticed that the latest ADC requires external bypassing on pin 0[4] or 0[2] to reach its full speed of 700 KSPS (dropped from the earlier advertised 1MSPS?) However, on the -050 DVK, the hardware schematics depict the connection of the decoupling capacitors at pin 0[3] or 3[2]. Cypress support, are you aware of this?

Show LessAll,
Is it possible to implement the bidrectional shift circuit attached with this post in PSoC3 ?. If yes, we will be able to build a component around it in Creator.
This component will faciliate level translating bidrectional signal lines (example I2C SDA and I2C SCL lines) from one voltage level to the other eliminating the need for a level translator chip in the design. (level translation can be acheived by routing the bidrectional lines from one quadrant to the other, quadrants powered at different voltage)

Hi everyone,
If I embed a CY768013A (FX2LP) into my PSoC5 based system purely as an integrated debugger for programming and debugging the PSoC5 (same as on the first touch kits) then presumably the FX2LP device needs some firmware of its own. How do obtain the required firmware, and how do I programm this chip? Do I need to add a header for SWD and use something like the miniprog3 or can a brand new FX2LP be programmed via it's USB interface from scratch? Or have I missed something, and the FX2 comes already suitable and programmed as an integrated debugger/programmer?
Show LessHello All,
With the 2*VDAC Vref sourcing option, can you apply low voltages to the range? For example, with the VDAC, it is theoretically possible to set the range to 8mV (4mv*2). I would assume that this would probably cause a lot of noise, or cause a major reduction in SINAD. It seems that we also have to use external decoupling capacitors too.
If this is the case, what is the lowest range that we can set using the VDAC and still get good results? For example, would setting the VDAC to 0.512V give it a good performance range of 1.024V (0.512V*2)?
Any clarification would be helpful.

Have you ever wanted to add components to a schematic in Creator just to make it clearer to understand? Creator 2.0 now has Annotation components to allow significantly better documentation and readability of your PSoC Creator based schematics.

It seems that PSoC is more convenient for developing data acquistion system. For CY8CKIT-050 PSoC® 5 Development Kit, should I order extra DC or AC adapter to power the board?
Can you give me some examples how to use C to program an application to transfer AD data from PSoC 5 to PC? I also want to control the sampling rate and sampling lengthe and even trigger from PC.
Thanks very much.
