Author: ajoyraman

Creation date:

Evaluation Type: Independent Products

Did you receive all parts the manufacturer stated would be included in the package?: True

What other parts do you consider comparable to this product?: Considered low power micro-controlles from Microchip

What were the biggest problems encountered?: Integrating the ADC of ADS7042 along with the pFatFs library in LPM3.5 mode so that ADC and SD-Card write could function simultaneously in the active period and be inactive during sleep in LPM3.5. and achieving the lowest power consumption.

Detailed Review:

It was a privilege and pleasure to conduct this RoadTest. I decided to build a practical application in order to exhaustively check out the features of the combination of the MSP-EXP430FR4133 LaunchPad development kit and the ADS7042 Ultra-Low Power Data Acquisition BoosterPack.


The full development details are available at: Full Development Details


1.  Project title: Anemometer and Wind-Vane Wind-Speed and Direction Logger


2. Project brief: A stand-alone unit operating from three AA batteries which is capable of measuring and logging wind-speed and wind-direction on a SD-card for a period of one year at intervals of 5 minutes or less with simultaneous display of interval-count, speed and direction on the LCD.


Using DIY hardware wind-speed is sensed by a cup-anemometer driving a small dc-motor acting as a dc-generator with output is in the range 0 to 300 mV. Wind-direction is sensed by a wind-vane which drives a one-wire potentiometer with a resistance range 0 to 24 kilo Ohm.


After signal-conditioning wind-speed is A/D converted by the ADS7042 and the wind-direction is A/D converted by one of the ADC channels of the MSP430FR4133. To achieve the lowest standby current the MSP430FR4133 is operated in LPM3.5 mode and the circuitry required for signal-conditioning, A/D conversion and writing to SD-card are switched ON only during the desired measurement interval.


An ‘Anemometer Booster Pack’ incorporating all additional circuitry and SD-card is specially designed and integrated below the MSP430FR4133 LaunchPad development kit while the ADS7042 BoosterPack with minor modifications is fixed above.


3.  Observations:


3.1. The OutOfBox_MSP430FR4133 example software compiled and ran without difficulty on CCS Cloud in ‘c’.

3.2. Following the Ti instructions and imported the BOOST-ADS7042_Firmware.ino file into CCS Cloud. It compiled and ran without any difficulty using Energia.

3.3. Three different methods for programming the MSP430FR4133 worked successfully:

3.3.1. Using FET-Pro430-Lite-3v41

3.3.2. Using the command line Flasher MSPFlasher.exe

3.3.3. Using the Cloud Based Flasher 'UniFlash'

3.4. After working with CCS-Cloud, CCS-6 and Energia-18 application development was continued in Energia-18 primarily because of ease in incorporating the Petit FatFS SD Card Library

3.5. Three modifications were carried out on the ADS7042 booster pack:

3.5.1. First the 3.3V line to the power LED (Green) before R34 was cut in order to reduce the card current drain of the LED.

3.5.2. Second the 3.3V line from the 3.3V tag to the SMD fuse F1 was cut and an additional wire connected at the input end of F1. This permits switching power to the booster pack as required.

3.5.3. An additional wire was connected at JP1 pin 2 for feeding the signal to be A/D converted instead of using the SMA connector for input.


3.6. Software development was carried out in stages. There was no difficulty in checking the LCD, ADC of MSP430FR4133, ADC of ADS7042 and the SD-card functions individually. Inconstancy was noticed when the ADS7042 and the SD-card functions were used together in LPM 3.5 mode.

The Energia-18 compiler gave inconsistent results when the SPI function from the example program for ADS7042 and the pfatfs functions were used together. Apparently the SPI function defined in pfatfs affects the SPI code defined for the ADS7042.

This problem was overcome by calling the ADS7042 ADC function during the period when pfatfs was open. However the combination of the ADC result MSB and LSB had to be modified to get the correct value.


3.7. A switching scheme was devised whereby the supply 3.3V to the booster pack and the ground to the SD-card could be selected by software control. In      LPM 3.5 mode the standby current measured was 0.01mA and the maximum current drawn was ~30mA during SD-card write.


As the Vref on ADS7042 booster pack has been chosen as 3.0V the supply required is 3.3V. This required three AA batteries and an external 3.3V regulator. The very low quiescent LDO Ti LM2936 was chosen for this.


With this LDO supplying 3.3V to the integrated set-up from an input of 4.5V the detailed current profile was measured to be 0.03mA when in sleep during LPM 3.5 and 38 for 0.5 sec during SD-card write, 22mA for .2 sec during SD-card close and another 1.5 mA for 1.7 sec during the active period.  This totals to 25.95 mAsec for the active period of 2.4 sec.


Considering a write interval of 5 min the estimate of power drawn for 1 year would be: (25.95 mAsec (active) + 8.93 mAsec (sleep)) x 12 x 24 x 365 = 3666585.6 mAsec or 1018.496 mAH. Alkaline AA batteries with 1.2AH capacity should theoretically meet the one year requirement.

5.    Project Details:

      5.1. DIY Anemometer and Vane

The Anemometer was built from repurposed parts. This includes a novel method of creating a one-wire potentiometer using a commutator-brush assembly from an old universal-motor and a DC motor from an old CD-ROM drive.


The wind-direction sensor is based on the commutator which is removed from the old motor assembly. With a hole drilled through the shaft and then 24 1kOhm resistors soldered between commutator segments and one end connected to the shaft. This creates a 24kOhm variable resistor between the brush and grounded shaft which can be used to determine angular position of the wind-direction.


The cup- anemometer is built using plastic balls which have been cut in half and fixed to a central hub using tapped aluminum rods cut from an old clothes-hanger. A small DC motor is driven by the rotating cup-assembly by a thin shaft which passes through the commutator shaft.


This creates a novel concentric assembly integrating anemometer wind-speed measurement using a dc-motor as a generator and commutator variable-resistance as a wind-direction sensor.


Using a simple method the anemometer was calibrated against wind-speed by fixing the assembly on a motor-cycle and noting the values of DC-voltage generated by the small-motor against speed measured on the motor-cycle speedometer.

7.  Summary


It was an great learning experience to carry out this RoadTest. I was able to work with all the IDE tools provided by TI including the CCS Cloud and CCS6 downloaded to my PC. The example and demo programs formed an excellent starting point for software development. The low power modes were fully exploited and it was impressive to see only 100uA in LPM3.5 which increased to only 300uA when the low quiescent current LDO was added. The major current contributor in the active period within LPM 3.5 is the SD-Card which needs 30mA for write operations.Integrating the SD-Card pFatFs library was a major challenge and some interaction was noticed with the SPI c-code of the ADS7042.   A work around was found for this. I worked mostly in the Energia-18 work-space as I found it easy to integrate the library functions of Energia with the other c-routines which needed to be added. The hardware provide has been very stable over several programming cycles.


Finally I must acknowledge TI and Element-14 for giving me an opportunity to carry out this RoadTest.

  • Ajoy,


    Your review left me speechless!


    You even custom designed an ‘Anemometer Booster pack’ ...."designed and fabricated so as to integrate with the the MSP-EXP430FR4133 LaunchPad development kit and the ADS7042 Ultra-Low Power Data Acquisition BoosterPack."


    I really enjoyed reading this. Your great writing skills really helped my understanding. It's always hard for me to select the best RoadTest reviews because our RoadTester community as a whole does a slam-dunk job. But this review has moved to the top of my list.


    A great job! Thanks.
