    The delay() function is part of the official Arduino API. It is implemented with a busy loop, based on the CPU clock. The sleep() function is not part of the official Arduino API. It powers down the CPU, and measures time based on the VLO, which doesn't have a accurately specified frequency to begin with and has much higher temperature and voltage coefficients than other clock sources.

    Below is a guide to get up and running with Energia BLE / Evothings Evothings for controlling your LaunchPad over BLE with a custom app on your mobile device: I have put together an app that allows to control of the RGB LED and Buttons exposed in the BLEInputOutput Sketch running on the MSP432 LaunchPad. At this moment it only runs on an MSP432 LaunchPad. Other LaunchPad's have bot been tested. To run the APP and control the LaunchPad follow the instructions below. You might have to upgrade the BoosterPack’s firmware. The firmware on my BoosterPack was not the right one so yours might not be as well. If you have issues running the app, then refer to updating the BoosterPack section below. Below is a screenshot of the app that I put together using Evothings to control the BLEInputOutput Sketch running on iOS. Running the APP on your mobile device: 1: Seat the CC2650 BoosterPack on the MSP432 LaunchPad 2: You will need the latest BLE library for crucial updates and new example Sketches. Get it from: https://github.com/ti-simplelink/ble_energia 3: Put the BLE folder in your person Energia/libraries directory just as you would install any other library. 4: Run Energia and open the example BLE->BLEInputOutput Sketch. 5: Verify and upload the Sketch 4: On your phone, download the Evothings Viewer from the app store. There is one for iOS and Android. 5: Open the app and then in the “Enter connect key” enter http://energia.nu/ble/bleinputoutput/ 6: Click connect. 7: The Energia BLE app should now open in the viewer. 8: Click he start button and the status should change to “Status: Connected” 9: You can now change the RGB sliders and you should see the LED’s on the LP match 10: Pressing the buttons will change the text for each button from “released” to “pressed”. Upgrading the CC2650 BoosterPack: The firmware on your BoosterPack might not be the right one. If you are experiencing issues with running the app, you might have to upgrade the firmware on your CC2650 BoosterPack. We are working on making this cross platform and to accomplish for Energia users. For now Smart RF Flash Programmer 2 has to be used on a windows PC. 1: Download Smart RF Flash Programmer 2 2: Remove JTAG headers from MSP432 LP (TDI, TDO, TCK, TMS) 3: Remove the BoosterPack from the LaunchPad (you will need a RED MSP432 LaunchPad) 4: Attach 10 pin ARM ribbon cable (included in the BoosterPack box) to XDS110 header on the emulation side of the MSP432 LaunchPad. Attach other end to CC2650 BP. It is keyed so there is only one way to attach it. 5: Get the SNP images from this link: http://software-dl.ti.com/dsps/forms/self_cert_export.html?prod_no=ble_2_02_simple_np_setup.exe&ref_url=http://software-dl.ti.com/lprf/BLE-Simple-Network-Processor-Hex-Files 6: Once installed, find the image simple_np_cc2650bp_uart_pm_xsbl.hex 7: Plug the LP into your computer. 8: Launch Smart RF Flash Programmer 2. 9: The CC2650 should show up in the left pane titled “Connected Devices” 10: Right click the CC2650 and select connect. The status bar should say “Success!” when finished connecting. 11: On the “Main” tab, in the “Flash Image” field select single and then browse to the simple_np_cc2650bp_uart_pm_xsbl.hex image. 12: Still on the main tab, under the header “Actions” check “Erase”, “Program” and “Verify”. 13: Then click the Green Arrow image on the right bottom to program the image. 14: Remove the ribbon cable, replace the JTAG headers and reseat the BoosterPack. You are now good to go to run the Sketch/App.

    Thanks @Clavier for the explanation.To add to this. The VLO is only used if the startup code does not detect an external crystal to source ACLK from. @tapasxplore Note that the MSP430 max VCC is rated @ 3.6. Robert

    Hi Rei, Thank you for letting me know, anyway I have already modified the Adafruit GFX library so it now runs on the CC3200, I will publish it as soon as I finish some last cleanups, During the process, I have learned about some compilation differences between Arduino and Energia which I'd be happy to share if there is any interest Thanks Guy

    Yes - you can use GUI Composer 2 (at http://dev.ti.com/gc) to create a GUI for your MSP430G2553 device. You can either use JSON-formatted strings for communicating with the target over the serial port (see http://dev.ti.com/gallery/search/MSP430G2553_LEDs_and_Temp_Demo), or you can use a target-side monitor and communicate over the serial port with the monitor (see http://dev.ti.com/gallery/search/blinky_for_MSP430G2553 ). Regards, Brian

    So, in case anybody else is curious, I've got the answer to my own question. Rename your bin to "mcuimg.bin" In Uniflash, go to the System Files, find /sys/mcuimg.bin Click the BROWSE button for URL and navigate to your file. Mark Erase, Update, and Verify. Go back to Flash Setup and Control, click Program. Enjoy. I really have to say that this is fantastic.I'm going to see what functions I can duplicate from CCS this way.

    Improved homing cycle has led to (near) perfect registration of solder mask. Layer registration mark, lines are ~0.1mm wide. Part of TSSOP 20 footprint, mask is way past "use before" date so some problems with spots appearing. I have started to apply the Riston film on wet PCBs, dust problem nearly gone - easier to handle.

    Hello. I figured I would share a project I've been working on since I borrowed a lot of code from this forum. It's a small watch using a g2553 and the same OLED display as "The Terminal". Thanks bluehash for the breakout, RobG and gwdeveloper for code, and others.

    Well, it's up and running. All the hardware seems to check out. Display and accelerometer are playing nice on a shared spi bus. The FR5738 RTC is keeping time. LIS3DH initialized and generating interrupts properly. Lots of programming to do now for the interface, calibrations, etc.
