The MSP432 controller is a low power ARM Cortex M4. TI Marketing Dept. say: low power, high performance. I'm not looking for high performance. Low power is what I'm after at the moment. Rather than just believing the hype, I'd better measure power myself. So here I go, measuring the power consumption with a µCurrent and with EnergyTrace. And I'm comparing the values.   Spoiler warning: measured values match close to the reported ones.     What is EnergyTrace?  ...
The Educational BoosterPack MK II, the Texas Instruments kit with loads of goodies. Who hasn't seen it? I have one. And I have plans with it. I want to turn it into the user interface for a safety features test bed for Hercules micro controllers.    I finished the last blog rather abruptly. I ported the essentials of Rei VILO's LCD_screen Library Suite to Hercules. But it wasn't working. My claim then was that the port was correct but the screen wasn't reacting...     Getti ...
The Educational BoosterPack MK II, the Texas Instruments kit with loads of goodies. Who hasn't seen it? I have one. And I have plans with it. I want to turn it into the user interface for a safety features test bed for Hercules micro controllers.    This time I ported Rei VILO's LCD_screen Library Suite to the Hercules SPI api. I have the essentials ported. The screen is not working though. That's OK. I learn when things aren't working straight away. And I have enough material to p ...
The Educational BoosterPack MK II, the Texas Instruments kit with loads of goodies. Who hasn't seen it? I have one. And I have plans with it. I want to turn it into the user interface for a safety features test bed for Hercules micro controllers.    Today's exercise is to hook up a logic analyzer. I'm going to PWM the LCD backlight as a proof of concept of that setup.     Set Up the Logic Analyzer  I have matched BoosterPack singals with the LaunchPad functions in t ...
The Educational BoosterPack MK II, the Texas Instruments kit with loads of goodies. Who hasn't seen it? I have one. And I have plans with it. I want to turn it into the user interface for a safety features test bed for Hercules micro controllers.    The Hercules family is specialized in safe operation and safe failure. It's used in automotive, industrial and medical applications where reliability and resiliance to mishaps is key. All modules inside the controller - including the ARM ...
