PSoC4 Smarter Life Challenge - DAS Project: Update Interfacing

bose

I have finalized on the Pinning and port configuration of the DAS project.

As of now I am able to interface the following parts:

1. LCD - Nokia 5110 over SPI (UDB based)

2. SD Card on the Adafruit Logging Shield on SPI (UDB Based)

3. RTC DS1307 on Adafruit Logging Shield on I2C (SCB Based)

4. LDR Sensor using ADC

5. Glass Break Sensor using OpAmp block (This part would be an emulated version as I could not get the actual part)

6. Door Knob CapSense

7. 3 CapSense Buttons using the Existing Slider

8. Tamper Switch

9. GSM Module using Ardunio GSM board on UART (UDB Based)

10. Sounder using the DC-DC converter

11. PIR Sensor using Interrupt/Capture port

12. HOST interface with PSoC5 using UART (SCB Based)

 

Here is a picture of all the external Interfacing parts:

This a rough Paper version, I will update this to a PSoC 4 creator version as soon as I can get the Annotated part of the Pioneer kit.

As you can clearly see nearly all the pins of the PSoC4 Pioneer kit are used. So this presently lacks capacity to handle all the sensors that I had listed initially.

Once the Initial proto works for most of the Sensors and Modules , I go for a full scale PCB to get the Final Proto.

At that time I would be able to have the complete interfacing done with all the necessary sensors and modules.

The software by then would be ready and additional interfaces can be added easily.

Additionally for DATA storage of some hard stuff such as User phone number and Alarm mode,

I would be using the EEPROM emulation component to store it directly to PSoC4 Flash.

 

Please feel free to post your valuable suggestion on how to address the first proto design quickly of any additional features that would be good to have in the Final Proto.

    Yes you are right, I have to carefully consider the software integration for all the features.

    Most of them are passive and non parallel apart from GSM communications. So not much of interrupts or need of special RTOS driven design.

    The problem with the software is that if its compiled in debug mode it would not fit. Possible module by module integration into a separate project in Cypress Creator is better, as suggested by DAB.

    In terms of features actually 90% of them workout but still there are LDR and a PIR sensor I would like to add.

    The reason being additional range and full directional coverage. This also with respect to the location of the system.

    I think for the first proto this is alight. Next when it comes to the PCB stage I can easily add the additional LDR and PIR.

    Plus the real Glass break sensor would be available by then. I am presently simulating it using a 555 chip to generate the required square wave/1-shot.

  • Nice overview. Have you seen how well you can integrate all features in software?

    Regarding integrating additional features: which ones are missing now? The list looks fairly complete

  • Looks like a good start.

    I would recommend adding each feature one at a time.  That way you only have the new stuff to debug, well mostly. image

     

    Have fun,
