  • No, Cypress CapSense solutions are much superior. There debugging and tunning tools are excellent to work with.

  • Does everyone understand this venn diagram?

  • Just get the I2C bridge for PSoC microcontrollers and don’t waste your time with an Arduino approach. The PSoC are the best and most versatile MCUs on the market. The Arduinos are kids toys compared to these. The I2C bridge is a very powerful debug tool and its all ready to go out of the box. $30 for a programmer is nothing in the world embedded development. You can analyze any variables or parameters in your code and output them on the I2C protocol and store/graph all day.

  • This book is a great buy. I read this several years and it was a great resource for Timer and OpAmp projects. I still reference it every once and awhile today. I really recommend this book over the others in the series.

  • The PSoC MiniProg CY3217 is the best for programming it ($30 on digikey). I use these all the time for work, i love the 21x34 series as they have a built in hardware capacitance sensing module. I also use Cypress I2C-USB Bridge Kit for software debugging. It is a fairly easy device to use and it has some neat charting and datalogging features.

  • Good article, it worked on my sensor interface. I have done something similar to this with AC line. I used 3 high valued resistors to reduce current and then clamp the voltage to logic levels via internal clamp diodes. With three resistors, one capacitor, and a microcontroller I made a basic touch interface.

  • Have you had any issues with pads or traces being pulled up? To be honest this doesn’t seem like the best approach. You can remove components just as easily with solder and wick if you know what you are doing.

  • You could try piezoresistive sensors instead of IR. Then you could adjust for tone of the sound as well. Or another thought would be setup a capacitance touch circuit using the stairs and measure that. With some handy coding you could detect walking up the stairs.

  • Why do you replace the IR with piezoresistive sensors instead? You would be able to add tone the sound being played.

  • If you have the PSoC Designer suite, then you would open it up and click on the help menu and then on documentation. The datasheet for Cypress PSoCs come with their software. You can either reference the datasheet on the Device (or its Family) or the Technical Reference Manual (TRM) for all the information on using the processor (Registors, Interrupts, Memory, etc..)

No public wish lists :(
