integrating accelerometer with Psoc development kit

[calvinlyp]

hi all,

i am relatively new to Psoc development pardon my ignorance.
i am currently working on integrating accelerometer with the development kit.

i found an article on
http://www.cypress.com/?docID=19786

after consulting an expert, he noted to me that the application note i had referred is for connecting an Accelerometer to PSoC1 devices which have SAR and ADCINC incremental ADCs. PSoC3 does not have a SAR8 user module. Instead i can use the ideas proposed in the application note but substitute the ADC with the Deltasigma ADC from PSoC.

my doubts was the figure 3 of the block diagram of accelerometer with PSoC. the control software block does it co response to PSoC3's control register? same goes to the I2C block can it be replace by the component using the PSoC creator IDE?
as there is not a direct info on how i can edit the value of the blocks, i hope to get some kind expertise's advice on how about i can cont to work on this article.

any help will be greatly appreciated.

Having a SAR vs. a Del-Sig ADC for this example shouldn't be too big of a change (as long as the Del-Sig meets your sampling rate). A much bigger change is moving from PSoC Designer's design methodology to PSoC Creator.

Our PSoC 3 FirstTouch Starter Kit has an accelerometer on it, and we have some example projects in that kit that use the accelerometer. You might find it useful to download those example projects and look at how the interface was created. You can find the example projects at http://www.cypress.com/go/cy8ckit-003.

If you install the kit software, it will install the example projects into PSoC Creator.

Hi Bobby,

thanks for the information.
i did notice that PSoC 3 FirstTouch Starter Kit has an accelerometer on it, however i had already bought the PSoC development kit, thus have no choice but to use the kit.

ya i am having quite a problem as i do not understand the differences in of the two.
is there some reference i can look into to so call "convert" the methodology use in the article (http://www.cypress.com/?docID=19786 ) to used in the PSoC creator and PSoC development kit?

thanks.
