PSoC™ 5, 3 & 1 Forum Discussions

Hello,

I am currently developing a spectrometer for gamma radiation using the CY8C28433 for this project. I want to start the SAR10 ADC upon an external event (pulse detected by comparator).  The SAR10 datasheet mentiones that the ADC may be started in autotrigger mode by  a comparator output, i can´t find however a hardware trigger input on the SAR10. How do I trigger the SAR10 by hardware instead of software and how is the source connected ?

Best regards

hello everyone!

I have some problems when I try to implement a project with amplifiers. the PSoC is CY8C29466, the input is a dc voltage from 0 to 15mv from a sensor, I want to achieve an output in the range 0 to 5V. 

 I selected a 3 op-amps and set the gain. however when I want to add a PGA after the INSAMP I find it seems impossible, can anybody tell me how to do that? btw, if i use a 2 op-amps it's possible...

the second problem is about the AGND, as is showed in the data sheet, the AGND is Vdd/2, and also can be set by the parameter ref mux in the global resource. since my interest signal is alwasy positive, so I tried to set Vss as  reference voltage for 2 op-amp INSAMP and PGA, but the noise is quite big and  I even can't observe the output signal...what's more, this method is impossible for 3 op-amp INSAMP. so I want to know may I set the "ref mux" p2[4]+/-p2[6] then connect p24 to GND and p26 to VSS?
 
thank you for your help!

 Capacitive sensors(like Humidity sensor) can be interfaced with PSoC and capacitance of sensor can be measured using various methods namely

1. Configuring analog block as relaxation oscillator

2. Using the Capsense architecture  itself which saves extra analog block and pins used in relaxation oscillator scheme.

So if you are using Capsense in your design u can also add capacitive sensors just as buttons.

hello,

When ibuild my project  in  PSoC 5 I am facing Two  ERROR

1) ""arm-none-eabi-gcc.exe"" failed with exit code '1',

2) few arguments to function "ADC_IsEndConversion"

I am Sending a pic related to this error

Please help me out of this.

Hello!
I have a simple question. Is it possible with a PSoC 5 First Touch into sleep mode to come? My PSoC 5 will not go into  the ILO 1 kHz clock mode.In sleep mode, my board has a current of I = 40mA. What's the problem?

Can you help me with this problem?
