PSoC™ 5, 3 & 1 Forum Discussions

Hi,
I'm new here and new to cypress. I have measured the variable resistor on board with the multimeter and find that it ranges from 0.27V to 3.23V. And when i connect the variable resistor to the Delta Sigma ADC and print it on the LCD, it print out the digital value in Hex. I tried using a formula, to get back the input analog value for checking in this form, ADCResult/Total ADC bits resolution * max input voltage. I convert the ADC Hex value output into a int variable to do the calculation and realize i do not get back the same value as the analog input. Also i observe that the output of the ADC printed on the LCD does not seem to scale with the variable resistor when i was turning it. Can anyone tell me what's wrong?

I am beginner with PSoC 5 and I started with a simple project.

I want to toggle a diode (Pin_2 on the schematics) with a push-button (Pin_1 on the schematics). In order to do that I am using GlitchFilter to debounce the push button.

Everything works just fine when I step through the program with a debugger, but as soon as I run the program, it stops working. It enters the interrupt just once and then stops working. It looks like interrupt routine do not respond. And there is no difference if interrupt is triggered as "rising edge" or "derived", it does the some thing.

I hope that some of you can see what the problem is.

Here are design, and code for main.c and isr_1.c (interrupt routine).

Thanx in advance.

Does psoc5 chips support in system programing via usb using device firmware upgrade protocol?

can everything be programmed using isp or a programmer is needed for some things?

I hava a neetbook with linux ubuntu ,what development tools can i use?

I'm curious as to whether I could use two iDAC to create a constant current biphasic pulse to stimulate biological tissue. I don't completely understand the iDAC compliance voltage and how it would relate to my project. I would like to produce a 100 microAmp pulse with a total duration of 1 ms, and the load will be 0.5-1.0 MegaOhms.

Cound someone comment on the iDAC compliance voltage, and if my load and current requirements would be possible using the iDAC.
