The Design and Build
Introduction A few months ago, Element14 and Texas Instruments Challenged us to create a wearable with the MSP432 with the theme of keeping us safe. I proposed to create a wearable jacket that could relay important information and sensor data from the cloud or station to the wearable and vice-versa. My initial proposal and plan are available at Safe & Sound - Safety Jacket for the Tolling Industry ...

d. Some more tasks
With the last week upon us, its time to complete this project and hence the home stretch. In this post, I am going to start by explaining the mutation of my design, the change in design and then the ...
This post is about enclosures and in particular about a case I designed for the Texas Instruments CC1310 that will fit about anything. Since there are no official enclosures out there for the LPs I though I would give it a shot. The difference between this one and a soap case is the ability to use the Launchpad while in the protective housing. The objective here is to keep the launchpad safe and sound and hence this case has the necessary features to do exactly that. The design has no wa ...
Log #8 This week I have been up to no good again and the focus of my experiments have been the BQ25504 and BQ25570. The EVM we received from TI and E14 is that of the BQ25570 Energy Harvesting to Battery charger and has all the necessary components and a little too many jumpers. I connected the EVM to a solar panel as well as a superCap in the hopes of making use of power supply. This is what I came up with.
In the above video, it is clear that the LED which us ...
Introduction I have missed the last week’s post due to a number of reasons and this week I am presenting another facet of the TI Platforms. I have been working with the various components of the kit to understand their working and how the code works. In this instalment, I explain Code Composer Studio and the TIREX or TI Resource Explorer. CCS Cloud Going to https://dev.ti.com/ide/ presents the user with a login form after which Code Composer Studio Cloud is lo ...
Its been two weeks since my last blog posts and my absence has been due to good reason. I am pursuing my PhD. where lab machine time is hard to come-by. Coupled with some health issues, the last two weeks have been the most hectic ever. In this post I continue some basics of protocol design and next week, I will move to finally document the implementation of the project itself. What is TLV? A quick search on google reveals that TLV stands for Type-length-value. In ...
I have been working with industrial control for more than a decade and have come up with my own 'hacks' to create a working system. This is my input for those who want to understand the process of writing a protocol stack.. at least my process anyways. In this two part series, I take a look at implementing a ModBUS like custom protocol in general and in part two, I will implement it using TI RTOS and the MSP432 board and it's UART. The objective will be to talk to a peripheral successfully and t ...
A few words
Beginning Its another friday and this week I am pleased to report the event-free delivery of the kit. The contents have been explained in the past but every box is a new surprise and hence here I present my unboxing video. The Video
https://youtu.be/WHAoN0gPrjs A few words The MSP432 Launchpad features an ARM cortex M4F and has DSP acceleration capabilities. In addition to the Pinout Diagr ...
Getting started with TI RTOS and CC1310
What is an RTOS
The CC1310 sub GHz launchpad
Getting back to TI RTOS
What is POSIX
Getting started with TI RTOS and CC1310 The CC1310 is a sub Ghz single chip solution that run its RF core on a Arm Cortex M0 and the Application processor is an Arm cortex M3 which means it is very flexible in terms of applications. Since things can get very complicated very quickly, TI recommends not developing native applica ...
So with the hardware delayed and my office space being reduced to a small box, I am working with a number of things. I installed the Code Composer Studio Software and it turns out I have some Anaren CC110L Booster packs in my inventory. So I decided to do a simple experiment with it. INTRODUCTION This is a simple prject where I use MSP430G2553 Microcontrollers with the Anaren CC110L Booster Packs to make a simple wireless node system. Nothing fancy and a barebones started project i ...
Yes. I AM running late on this blog post and yes I read the terms and conditions. The delay was due to unforeseen blunders on my part but here we go... Here is my application for the challenge and where I put my foot in my mouth!. A few points to note: 1. Yes you can make fun of my drawing. 2. No I did not use crayons. 3. Yes I have crayons of my own- my wife bought three sets for my son, me and herself. 4. Yes this is a serious project. 5. And yes I will be using paper draw ...
