This is a video in support of an Element14 road test I performed a little while ago, if your looking into building your own switching power supplies this chip might be for you In the video and the following two I review the TI Simple Switcher Evaluation module to see how it performs under various load conditions..First up is varying the input volts through the 6 to 60V range with a constant 5V 500mA load to see if the output can maintain stability and accuracy over this range. As you will see it did not flinch my conclusion is the chip is able to perform in excess of the evaluation boards specefications Here is ia link to the Element14 Roadtest web site for the board http://www.element14.com/community/roadTests/1373 and the chip data sheet from TI http://www.ti.com/lit/ds/symlink/lm46002.pdf ... https://www.youtube.com/watch?v=rRpGgLNx-UI

In the previous video I showed how to get various displays working on the SAMA5D4 Xplained Ultra development board Now we will look at using the various IO capabilities on the board and also how to hook up to external devices via the I2C bus The image used can be found here: ftp://ftp.linux4sam.org/pub/demo/linux4sam_4.6/ A bunch of useful info I used to compile this video can be found at the following urls http://www.atmel.com/Images/Atmel-11238-32-bit-Cortex-A5-Microcontroller-SAMA5D4_Datasheet.pdf http://www.at91.com/linux4sam/bin/view/Linux4SAM/ http://www.at91.com/linux4sam/bin/view/Linux4SAM/GettingStarted http://www.at91.com/linux4sam/bin/view/Linux4SAM/IioAdcDriver http://www.at91.com/linux4sam/bin/view/Linux4SAM/UsingMaxTouch http://www.pdaatl.com/doc/tm7000.pdf https://projects.drogon.net/raspberry-pi/wiringpi/i2c-library/ http://www.atmel.com/Images/Atmel-44019-Cortex-A5-Microcontroller-Using-Display-Module-TM7000-on-SAMA5D4-Xplained-Ultra-Board_Application-Note.pdf http://www.pdaatl.com/doc/tm7000_sama5d3xpld_qs.pdf http://www.acmesystems.it/i2c http://wiki.erazor-zone.de/wiki:linux:python:smbus:doc http://www.mmnt.net/db/0/0/www.linux4sam.org/pub/Trainings/at91data/ipk ftp://ftp.linux4sam.org/pub/demo/linux4sam_4.6/ http://www.atmel.com/Images/Atmel-44019-Cortex-A5-Microcontroller-Using-Display-Module-TM7000-on-SAMA5D4-Xplained-Ultra-Board_Application-Note.pdf ftp://ftp.linux4sam.org/pub/demo/linux4sam_4.6/linux4sam-poky-sama5d4_xplained_pda7-timesys-demo.zip ftp://ftp.linux4sam.org/pub/demo/linux4sam_4.6/ http://www.atmel.com/Images/Atmel-42328-Using-SAM-BA-for-Linux-on-SAMA5D3-Xplained_Training-Manual_AN8995.pdf http://www.atmel.com/Images/Atmel-44005-32-bit-Cortex-A5-Microcontroller-SAMA5D4-Xplained-Ultra_User-Guide.pdf http://www.atmel.com/Images/Atmel-44019-Cortex-A5-Microcontroller-Using-Display-Module-TM7000-on-SAMA5D4-Xplained-Ultra-Board_Application-Note.pdf http://www.at91.com/linux4sam/bin/view/Linux4SAM/IioAdcDriver ... https://www.youtube.com/watch?v=w_QbB4NwJ-o

Adding the Texas Instruments SHARP96 LCD Boosterpack. Celebrating TI IoT week, I am building an IoT node that will monitor the Temperature and Light Levels of wherever you place it. TI products will be as much as possible the heart being a TI Launchpad CC3200. Temperature sensing has been added and today we add the LCD display, by the end of the week we will have a fully working IoT node that will post the data upto an MQTT server (The Cloud) and provide you with the means to subscribe to that data and present it in a useful way on a Smart device via an HTML5 browser. In this video we will add a 430boost-sharp96 display so that we can see the readings locally bit still keep the power consumption real low. If you want to replicate this project, it should not cost you more than 50-80$ depending on your current parts and options you choose. The launchpad selected for this project is the CC3200. http://www.ti.com/ww/en/launchpad/launchpads-connected-cc3200-launchxl.html#tabs TI Temperature sensor selected for the project is the TMP275 TMP275 http://www.ti.com/lit/ds/symlink/tmp275.pdf The Display is the 430BOOST-SHARP96 http://www.ti.com/lit/ug/slau553/slau553.pdf and purchased from here http://www.ti.com/tool/430boost-sharp96 or other vendors of your choice I would like to thank Texas Instruments for their support and sponsorship with this project Other videos for this series can be found here:- Day 1 https://youtu.be/im-ip8ZAXjY Day 2 https://youtu.be/QfE8kPg5cWk Day 3 https://youtu.be/feak2L_gM_w Day 4 https://youtu.be/AwO9qjMBsiE Day 5 https://youtu.be/5RdPFRs1cAc Day 6 https://youtu.be/f48pHgzB6VE Day 7 https://youtu.be/fpYWajndIOQ ... https://www.youtube.com/watch?v=feak2L_gM_w

In an effort to evaluate simple and accurate display for my various Power projects a little while back including my analogue DC load , I found and bought some panel meters from aliexpress here http://www.aliexpress.com/item/Blue-Red-Dual-LED-Display-4-bit-0-28-Digital-Ammeter-Voltmeter-Car-voltage-current-meter/1505911610.html on initial examination hey seemed to have issues when used for all but the basic systems but...... on receint examination I discovered that they use a seperate differential input ADC chip to read the current that has markings "CA2P" and had shorted the negative input to the 0V rail of the power / Voltage sense input with a zero ohm value resistor negating its differential ability and in the processess limiting its flexability. I will show you here how to Hack it back to a differential input and how I integrated it into a DC Load Now these displays have a whole new lease on life... ... https://www.youtube.com/watch?v=A6VQhDioz_Q
