Scan Interface Applications - Five Members Win A Target Board And An MSP-FET

Recommended Posts

Contest time!

Five winners get a MSP-TS430PZ100($89) target board along with an MSP-FET($115). Five!

 

This contest is in partnership with TI. They are looking for ideas and applications that could make use of their Extended Scan Interface(pg 744) or ESI. One of the biggest markets of the MSP430 is flow metering which is where this module is widely used.

 

1. Come up with an application using the MSP430FR6989 chip ESI.

2. Write it down below.

3. If you win, you implement your idea with your kit and get featured on TI's MSP430 Blog.

 

Rules:

1. You have to have at-least 5 reputation points.

2. Keep a small project log in the Projects section. This is so that it can be published later on TI's Blog.

 

Dates:

  • Contest begins August 15th, 2014.
  • Contest ends August 30th, 2014.
  • Winners will be announced first week of September.

Wow. That's quite a complicated peripheral - or at least it seems so from the datasheet.

 

I've got a project that includes flow monitoring but it seems a little bit too simple to need ESI. I might write it up anyway. We just enter the idea in this thread now and write up in the projects section later, is that right?

Yes..

If are one of the winners.. you get the board and FET and log it in the Projects section.

My landlord keeps calling me asking why the water usage has increased dramatically- I get that call every 3-4 months. He sets the sprinklers to run at 4 am, but the neighbors somehow have theirs running at 7 pm every day. Thing is, the water supply enters the duplex on my side and splits off from there, so maybe something like this would allow the landlord to discern which of us tenants are using the most water.

 

One flow meter where the water enters the duplex, and another after where it branches to the adjoined dwelling would allow him to figure out who is using the most water.

 

Total water minus the neighbor's water equals my water use.

Mine project would be to monitor coolant flow and temperature for my laser cutter. The quickest way to destroy a laser is to run it without the coolant flowing and overheat the tube. Unfortunately the cheap Chinese 40W CO2 lasers you get on eBay have and entirely separate water pump that you have to remember to switch on manually. Forgetting to switch it on (or if it gets blocked / too hot) and your tube is quickly fried. I know this is well within the capabilities of a simpler MSP430 just counting pulses from a hall effect sensor, but the ESI sounds perfect for the job and would leave the rest of the FR6989 to get on with more interesting stuff - pulsed laser firing or working as a DSP to control the laser (for engraving, etc.).

 

[Edited for a bit more detail]

The ESI would be used for it's primary purpose - "to automatically measure linear or rotational motion with the lowest possible power consumption" - paired up with a simple hall effect liquid flow sensor. It will hardly be stretching the peripheral to it's limit but should cover its basic use. As far as low power goes, it'll be on a mains powered laser so not exactly essential. I'll be monitoring the temperature of the coolant entering and leaving the laser tube. The laser will be disabled if the flow is too low, the exit temperature is too high or the difference between the entry and exit temperatures is too high.

 

It'll have an LCD screen to display the temperature and flow. However I've got a cheap SPI one, so I doubt there will be any reason to use the inbuilt LDC_C controller.

 

Phase 2 may involve measuring the speed of the two axes from either an encoder (better) or the pulses to the steppers (easier). If you know the speed of movement of the laser head then that allows better control of the laser power. Without this you tend to get a dot at the start of the cut as the laser powers on but isn't moving yet.

Here is my idea. It's a bit different.

 

A better fitness monitor, Built into a shoe. The ESI would be used to drive and measure pressure sensor(s) to detect walking/running/standing.

 

This application would also benefit from the MSP's ultralow power. The entire system could potentially be powered from kinetic energy harvesting.
