PSoC™ 5, 3 & 1 Forum Discussions

Did you know that you could program a PSoC without using a MiniProg? 

Programming a PSoC device is done using a protocol which is very similar to I2C communication. It is very much possible to use any MCU that can act as an I2C master to implement this protocol and make it program any PSoC 1 device.

More details on how you can do this can be found here - http://www.cypress.com/?rID=2906

good article.

Very Good Article.

PSoC digital blocks can operate as 8-bit pulse width modulators (PWM). Due to the special design of the PSoC, these modules do not incorporate glitch-free hardware logic but instead logic must be considered in software.

As seen from the image below, the problem lies in the absense of hysterisis in the comparisons taking place to generate the digital output.

A workaround to this is presented in the following document: http://www.cypress.com/?rID=2801

interesting app note.

Mechanical keypads are commonly available in two forms – matrix and common bus (depending on how individual switches are inter connected) :

There are multiple ways in which you can use a PSoC 1 to read mechanical keypads.

Appnote AN2034 shows you how to read matrix and common bus keypads, in both polled and interrupt modes.
