Hello, I am attempting to externally power a MSP-EXP432P401R (rev 2.1) & CC3100BOOST (rev 3.3) independent of USB connections. I would like to power both off of the 3.3v bus only (via J6 on the MSP432), which sounds like it should be possible based upon the datasheets I have reviewed. I have set J8 on the CC3100 to the bypass LDO setting, and I am using the Energia SimpleWebServerWifi.ino example. What I have discovered is that the CC3100BOOST reports a significantly lower signal strength (-75 dBm) when it is powered up only on 3.3v. If I add in a 5v external supply or change the

Hi, this is my first post on the forum, hope I have put my query in the right forum. OS: Windows 10 IDE: Energia We actually just got started off using the MSP432 and the MKii kit, nearly all the examples work as expected, except the ones with LCD. We do not get any compilations errors, and the program loads fine and also we see the data over serial port after uploading the code. We see several suggestions about removing R9/R10 shunts, but suppose that doesn't pertain to MSP432(?) What are we missing here? In fact when we run the Code composer studio exampl

So, Indeed YELLOW_LED controls the red LED on the board. 8^) But I still can't get serial on my Mac to work reliably. I have set the baud to 115200 (Launchpad and Energia Terminal). I have tried Serial and Serial1. I have tried both usbmodems that show up, I do have USB 3.0, but I have no control over that. I have also tried the macOSX screen command which turns a terminal session into a serial console. The kicker is, one time I *did* get serial output to show up using this method. I was printing to Serial and Serial1 at the time. So I modified it to do one or the other but never again

I was inspired a while back by the simplicity of the FFT application written by Shane Ormond and featured on the 43oh blog. It was easy to duplicate and I've made a few changes, additions, and such that seemed worth documenting. I didn't have a signal generator other than the 1kHz square wave on my oscilloscope and some clunky code that I wrote for a microcontroller so I ordered an inexpensive AD9850 and hooked it up to a FR6989 LP so I could use the LCD to display frequency. I've been pleased with the AD9850 and it is hard to beat it for the price. The sine wave is more than sufficient

The MCP3008 is an easily used 10bit, 8 channel, Serial Peripheral Interface (SPI) Analog to Digital Converter. I created an Energia library that can be found here and used to read any of the eight pins with a single call. Conversion is done for voltages between 0 and 3.3 V, including on the CC3200, and results in a integer reading between 0 and 1023. This library is for single ended operation only and uses hardware SPI. An example is included that demonstrates reading from all 8 channels. Tested with Energia 0101E0016 on the following LaunchPads * CC3200-LAUNCHXL Rev 4.1 (80 MH

pinMode(n, INPUT_PULLDOWN) does not work on MSP432. The pins seem to function as input and the pull-up is always enabled in any input mode.

The SPI.setBitOrder() and SPI.setDataMode() function calls seem not to do anything on the MSP432 LaunchPad. They work fine with TivaC LaunchPad.
