Hello Peter,

I am trying to connect a Heart Rate Sensor that I have from another project.

This project used the Raspberry PI and an ADC on a breadboard connected to the Raspberry PI.

I would like to attach this sensor directly to the Starter kit, but can't figure out where to hook the three leads coming from the Heart sensor.

the original project Is on Hackster.io at

https://www.hackster.io/mohamedemam0/windows-10-iot-core-reading-heart-rate-pulses-e3af03

Here is some information about the project from the link.

I did get this working with IoT Core about a year ago and thought it would be a good project to try and connect it to the starter kit.

Heart Rate Sensor

BLACK: Ground
RED: Input: +3V or +5V
PURPLE: Signal

So, we need to connect the signal coming from the sensor to one of the channels in our ADC. To know how to connect the ADC, here's a scheme of our IC to know the function of each leg. (I got it from the datasheet of the IC, you can google it):

Any advice would be really helpful, I am a developer that has a limited knowledge about electronics.

I did not know how to post this request to the group.

Regards

Steve

Will Microsoft or someone else ever release a SDK compatible with Mac?

Thanks Peter

I went through it a second time slowly following your outline below, and all works fine. I do have a question for you. I have added a Mikroe Motion click (MIKROE 1589) in the click #2 position of the Azure Sphere board. I want to get the motion sensor (output on INT pin) to trigger either rely 1 or 2 on click board.

Can you assist with how to modify your project to be able to do that? (I have done it by switching the two mikroe boards motion click in click #1 and relay click in click#2 and jumpering between the two, but that does not work in your configuration.)

Any assist would be appreciated.

Tony

Note the following important update to this Azure Sphere 19.09 OS and SDK blog article:

A really important new feature is the availability of the optional --targeted-scan parameter (abbreviated as -t)

eg. azsphere device wifi add --ssid MyHotSpot --psk 12345678 -t
This will force connection to an SSID even if this not among the SSIDs reported by a Wi-Fi scan, or if located in a crowded wireless network environment

(Make sure to forget instances of the target SSID from list of WiFi networks currently configured, before adding an SSID with the -t targeted-scan parameter)

More detail on this topic is available here: https://docs.microsoft.com/en-us/azure-sphere/network/wifi-including-ble#enable-targeted-scanning

I also found the updated documentation does not state that
azsphere device wifi delete -id 0

has been changed to

azsphere device wifi forget -id 0

Having updated to 19.09, I am now getting "Real Time Core: ERROR" on the screen of the OLED when running the code used in your Advanced Tutorial (and no light readings obviously). I don't think anything else has changed. Do I need to recompile everything, or does the code need to change, following the firmware update?

[edited to change the reference to the code used]
