Tinkering TI MSP430F5529

Posted on January 29, 2020 by Shawon Shahryiar 24 comments

In my past tutorials on MSP430s, I demonstrated how to get started with MSP430 general purpose microcontrollers from Texas Instruments (TI). Those tutorials covered most aspects of low and mid-end MSP430G2xxx series microcontrollers. For those tutorials, TI’s official software suite – Code Composer Studio (CCS) – an Eclipse-based IDE and GRACE – a graphical peripheral initialization and configuration tool similar to STM32CubeMX were used. To me, those low and mid-end TIs chips are cool and offer best resources one can expect at affordable prices and small physical form-factors. I also briefly discussed about advanced MSP430 microcontrollers and the software resources

Introducing TI MSP430 Microcontrollers

Posted on August 25, 2017 by Shawon Shahryiar 14 comments

Texas Instruments (TI) is a well-known US-based semiconductor manufacturer. TI is perhaps best known to many as the manufacturer of some of the fanciest scientific calculators in the market. Of the long list of electronic devices produced by TI, microcontrollers are on the top. TI manufactures some of the coolest and advanced microcontrollers of the market today. There are several categories of micros from TI. These include general purpose low power MCUs which mainly comprise of MSP430s, ARMs like TM4Cs, MSP432s, etc, micros for wireless communications like CC2xxx series, ARM + DSP micros, DSP-specialized micros like the TMS32xxx series and

PIC24F Blood pressure monitor

Digital blood pressure monitors come in handy for checking and monitoring blood pressure at home or in a hospital. This reference design from Microchip provide tips to build a low-cost, low-power, handheld or portable blood pressure meter with user interface using the system-on-a-chip PIC24FJ128GC010 MCU. The meter is used with an inflatable cuff for restricting blood flow and a pump to inflate the cuff, and measures both systolic and diastolic pressures, as well as the heart rate of the patient.

Filter optimization for A/D conversion

Posted on October 12, 2016 by R-B Leave a comment

Filters are necessary to eliminate unwanted noise or distortion in a signal prior to any A/D conversion process. Designing a filter to pass the desired frequencies is easy, but it introduces signal loss, or insertion loss. Check out this application note from TI for some useful tips to optimize the filter design to minimize the losses. One of the first steps of filter optimization is the selection of the center frequency and the bandwidth of the filter. Once this step has been completed the task becomes one of putting the filter elements on the printed circuit board (PCB). PCB design is critical to
