This is my first self written HET program that actually works. You can define a number of timers and let them create an interrupt when they expire. I've created 8 independent 1µs resolution timers in this example. Many more are possible*1. All previous posts were to train myself for this. While porting a LoRa example from MBED to Hercules, I tried to create timers with interrupts on the Hercules just by winging it. That never worked. Frustration . By blogging about all the previous ex ...
A very simple HET example: Project1 - generate 2 PWM signals and simulate them with Synapticad Wave Viewer. In the previous posts I reviewed a HET application note called HET Getting Started. This time I use another application note called HET Getting Started. That one is for the TI TMS470 family but works perfectly with the TMS570/RMxx too. It's simpler, using a few lines to generate two PWMs with same frequency and different duty cycle. Ideal to show a simulation with Synapticad's WaveVie ...
A very simple HET example: Project0 - generate a PWM signal with a fixed duty cycle. The previous posts were a showcase: let the timer module do some calculations while generating and and measuring signals. In this much simpler post let's take a step back. The TI Application Note NHET Get Started*1 shows the core specialty of the HET module: counting   In order to create a fixed frequency pulse with a fixed duty cycle, only two lines of PWM code are needed:   L00: CNT{next = L01, ...
This project uses the timers of a TI Hercules microcontroller to generate complex digital signals and to measure digital signals.   In this post: measure the the duty cycle of the previous post and take actions when it's about a certain range. The actions are: put a pin high as long as the duty cycle stays outside the accepted range (error output) throw an interrupt to the host microcontroller     This project is based on TI's application note spna178: Monitoring PWM Using ...
This project uses the timers of a TI Hercules microcontroller to generate complex digital signals and to measure digital signals.   In this post: create a triangle wave by modulating the duty cycle of a fixed frequency pulse wave.     This project is based on TI's application note spna178: Monitoring PWM Using N2HET. That note explains the functionality and has a link to a Code Composer Studio project . I'm using these as the source for the blog series.   Triangle si ...
This project uses the timers of a TI Hercules microcontroller to generate complex digital signals and to measure digital signals.   The TI Hercules microcontroller has interesting timers. They call them high-end timers, HET. They are autonomous programmable subcontrollers. HET modules are specialised to run logic in a deterministic time. Whatever happens in the outside world. a HET block will grind through the steps, clock steady. It's a tough module to program for, though. All the abstr ...
The Lighting Market for Automotive is projected to grow at a CAGR of 6.80% from 2017 to 2022 and is expected to reach USD 29.97 billion by 2022. Increasing vehicle production and lighting applications are the key factors driving the demand for lighting in the automotive industry. With the increase in sales of electric and hybrid vehicles, the demand for lighting with low energy consumption is growing. Objectives of the Automotive Lighting Market Study: To define and segment the automotive lighti ...
The Hercules microcontroller family has a programmable timer coprocessor. In this post, I'm making it simulate an extra SCI / UART channel. With read and write interrupts. I did this exercise for a fellow member on the TI e2e forum, Praveen. He got most of it working, except the interrupts.It's 100% based on the application note UART Implementation Using the N2HET, but ported to one of the smallest controllers in the Hercules family - the TMS570LS04x -  that has a single SCI / UART con ...
This may be my slowest blog series ever - previous post was October '17.   I'm trying out basic CAN communication on a Hercules microcontroller. In this part I have my driver boards working.   I designed a tiny CAN driver PCB more than a year ago, for the Microchip CAN Bus Analyser Tool Road Test. At the time, it didn't work. Road Test stress and work and life prevented me from getting to the bottom of the issue. You can see some of my trials in the comments of part 3c: Design ...
China is becoming serious about leading the electrified future; they are looking for reducing its dependence on imported oil and decreasing the smog level in its cities while growing their Electric Vehicle (EV) market: near 375,000 EVs were manufactured by Chinese OEMs in 2016 (43% of EV production worldwide).   The Chinese government is giving an ultimatum to all automakers operating in the country: a sizable portion of their production or imports must be green in 2019, with escalating go ...
The transformation of the idle transportation industry will innovate during this year as transit systems not only move people and goods between places but mitigate time and distance —bringing us closer together. Some of the Transportation Technologies Driving 2019 are:   Will autonomous cars and trucks finally be around? There is no doubt that self-driving vehicles are becoming a commercial reality: almost all major automotive companies are (in-house or in partnership) developing an ...
As 2016 ignited the automotive revolution with significant announcements and concepts, 2017 completely paved the road for future mobility, and 2018 brought us semi-autonomous embedded features with safety technologies, 2019 will drive us (even more) forward on self-driving than ever before.   Several companies (like Waymo, Argo, Uber, Aurora, or Ford) together with joint ventures (like Google and Volvo or Renault-Nissan, or Amazon and Audi) and disruptive startups are focusing this year on ...

For automotive application, we presented latest products and technologies for CASE domains (connected cars, autonomous driving, sharing and services, and electric vehicles).   Part of our exhibition is now online, please have a look at our website. --> Alps in CEATEC 2018    Exhibited products and technology for automotive - Bluetooth(R) 5 Module (Low energy) - LTE/5G Data Communication Module - Magnetic Steering Angle Sensor ...
Smart Transportation systems are mixing embedded technologies, data processing capabilities, and telematics breakthroughs to develop a robust network of solutions that are changing the way everyone (users, organizations, and governments) are not only relating with vehicles, drivers and passengers, but pedestrians, roads, regulations, and more.   Carmakers are developing more secure and safer vehicles, more automated and connected to the outside environment than ever before.  Consequen ...
Vehicles are quickly evolving from being a simple way of transport to become a highly-computerized mobile hub. Modern cars and trucks are gradually turning into computers-on-wheels by plugging-in to the Internet to offer efficiency, comfort, and convenience, together with security and safety.   The Securing Connected and Autonomous Cars for a Smarter World report from the global business consulting firm Frost & Sullivan estimated new vehicles have about 100 Electronic Control Units (EC ...
