Need Someone for a Project: Cypress PSoc6 BLE kit +  Honeywell Pressure Sensor Shield

rscasny

I was contacted by a supplier who is interested in giving hardware for free to someone who could do a project for them featuring  Cypress's PSoc6 BLE kit +  Honeywell Pressure Sensor Shield.

 

They would like the person to do the following:

 

Interface the pressure sensors of the Honeywell Sensor Shield with the PSoC 6 analog/digital peripherals and then transmit data via BLE or showcasing it on the E-ink display of the PSoC 6 BLE Kit. The project should have some kind of medical application. For example, measuring pressure in some kind of health/medical application.

 

Just to refresh your mind, here are the parts involved:

Click here for more information on this Honeywell Sensor Shield. I have not roadtested this product.

 

I would like to do this sometime in October. I'd like to get it accomplished in a month--the shorter time period is why I am not offering it as a roadtest.

 

If you are interested, feel free to comment below.

 

thanks.

  • re: breakout boards

     

    I spoke with our sales manager. Doesn't look like the breakout boards are available yet.

     

    I'm placing the sensors part order now. I'll keep a watch out and if they come available, I'll order and send them to you.

    Hi Randall

     

    Well, I found a breakout board that looks good for the project.
    I found one at Adafruit that has the same MPRLS sensor and voltage regulator as well as a level shifter for the data signals on board.
    I would use this as "hello world".
    Because a voltage regulator and level shifter are included, it is easier to use than Honeywell's breakout board.

    Is this a problem to can get one as a sample kit? If not, no problem.

     

    At the Attachment there you can find the schematic and PCB for Eagle CAD.

    I thought as well for the others whether they need this.

     

    Best Regards

    Gerald

    Gerald,

    thank you for the effort. Frankly, me I have found this kind of breakout boards but - IMHO - what I dislike is the "mania" of Sparkfun to create breakout boards that are not really breakout as always includes minimal discrete components (and not only) to make the board compatible with some else, in this case, for example, I see what seems a current regulator for Arduino powering, or supporting a range of 3-5 V.

     

    The point, in my opinion, is we should operate as much "clean" as possible: this kind of project lies between prototyping, the study of the component features, the features of the producer kit and the need to underlying eventual problems with the components as they are sold so - but maybe I am totally wrong - the last thing we need is a working solution, different than the testing. Maybe I always chose the most difficult path... Maybe image

    Hello Enrico,

     

    I usually go the same way.

    Prototyping with the original parts and sizes to get as close as possible to the final product.
    I only thought of the module so that you could quickly say "hello world".

    However the costs are not everything for me. More important for me is the quality of the laboratory manufactured parts.
    I also equip a breadboard board as well as possible with "high" quality.
    But I would rather not use such a board because there are too many uncertainties in the background, e.g. RF issues, bypass capacitors, filters, etc.

     

    The voltage regulator is a 3V3 LDO fixed voltage regulator from Microchip (MICREL).
    This module is designed for I2C, so level shifters are included in the data lines.
    Thus one is tolerant 3 to 5V.

     

    The RESET input pin is protected with the 1N4148 diode, because RES is low-active the signal goes through,

    but higher voltages above 3V3 can not damage the sensor.

    I think this is very important to spend a bit more parts around the sensor.

    So if you work with your system on 3V3, you can bridge to the sensor these wires.

     

    I also posted the Eagle-CAD file, so you can easily customize everything.
    The module is very small, contrary to Honeywell's Breakout Board, that was actually my key decision.

    Here you do not have to solder the sensor by hand, it is better for the sensor, because then it was not overheated, hopefully.
