UPDATED August 24, 2018 at the bottom of the post with parametric data at different voltages and gains   I have a project in mind that will require op amps and have been testing the Texas Instruments MSP430FR23xx microcontrollers with built in op amps. Yesterday I did initial tests with the MSP430FR2355 LaunchPad and looked at how gain can be set from inside the microcontroller.  The input voltage of 32.7 mV was very close to the lower rail  (the rails are GND and 3V3) with gain ...
As noted yesterday I have a project in mind that would use operational amplifiers.  Several manufacturers have microcontrollers with built in op amps and yesterday I took a quick look at the MSP430FR2311 from Texas Instruments.  Today will be a quick look at the larger and more powerful MSP430FR2355 which can be obtained on a LaunchPad.  This is a relatively new product and I bought my sample from the Texas Instruments store as it is not yet available from Newark / Element14.  ...
I have a project in mind that requires operational amplifiers.  Recently Texas Instruments has released several microcontrollers that have low power precision op amps built in.  I have two in hand now that I will be testing - the MSP430FR2311 that is in this post and the larger MSP430FR2355 that I may end up using in my project.  I won't describe the parts in detail today but instead will fire the FR2311 up in a kind of hello world for op amps.   The FR2311 microcontroller h ...
The Element14 community was kind enough to award me a prize in the Open Arduino contest and with the award I purchased one of the official displays for a Raspberry Pi.  I have wanted a portable marine traffic monitor for some time and this is what I came up with: It turned out quite nice, went together easily, and can be put together at a reasonable cost.  The project is a good demonstration of how powerful the Raspberry Pi is.   Components: Raspberry Pi 3 Model B Raspberry ...
