  1. Can you please open a terminal and type the following command? kextstat -b com.FTDI.driver.FTDIUSBSerialDriver If it does not show something like the below then the driver was not loaded: Index Refs Address Size Wired Name (Version) UUID <Linked Against> 533 0 0xffffff7f831ad000 0x7000 0x7000 com.FTDI.driver.FTDIUSBSerialDriver (2.3) ECC3AF36-431D-370D-86F2-5237785E9CF8 <110 52 5 4 3 1> In that case try: find /Library/Extensions/ -name *FTDI* This should show something like the below if the driver was installed. If not then reinstall the driver. If it does show something like the below then read on. /Library/Extensions//FTDIUSBSerialDriver.kext /Library/Extensions//FTDIUSBSerialDriver.kext/Contents/MacOS/FTDIUSBSerialDriver If the driver is indeed installed and exists in /Library/Extensions then try to force load it with the following command and check id the Serial port shows up in Energia. sudo kextload -b com.FTDI.driver.FTDIUSBSerialDriver After this you can check if the driver is loaded with the command I listed above.
  2. Can you please provide details on what you see? What does ls /dev/tty.* show?

    Sleep frequency - 999ms vs. 1000ms

    Which version of the msp430 package are you running? I don't have access to a MSP430FR2433 LaunchPad right now so ma not able to reproduce. Could you try replacing the setup loop with jus a pinMode(LED, OUPUT) to test if it you do see a 2 second blink?

    i2c communication not working on msp430fr5969 rev 2.0

    I spaced out on this. Tank you to one of the developers for reminding me. The msp430fr5969 does not have hardware I2C on pins 9/10 and thus no I2C slave on those pins, only software master. It does however have both hardware slave/master on pins 14(SCL)/15(SDA). This module can be activated by calling Wire.setModule(0) before Wire.begin(). Please see Sketch below as an example: #include <Wire.h> void setup() { Wire.setModule(0); Wire.begin(4); // join i2c bus with address #4 Wire.onReceive(receiveEvent); // register event Serial.begin(115200); // start serial for output } void loop() { delay(100); } void receiveEvent(int howMany) { while(1 < Wire.available()) // loop through all but the last { char c = Wire.read(); // receive byte as a character Serial.print(c); // print the character } int x = Wire.read(); // receive byte as an integer Serial.println(x); // print the integer }

    I just ran a test here and I2C slave indeed does have some issues on the FR5969. We will look into it. Robert

    Please provide both the Sketch you run on the Uno and the msp430fr5969 so I can look into it.

    MSP432P401R: example/library for gps

    That library should work with Energia/msp432 from looking at it .

    MSP432 Error compiling to board

    I reproduced the issue. Below is how to work around it. open the folder %LOCALAPPDATA%\Energia15\packages\energia\hardware\msp432e\5.19.0 Open the file platform.txt in a text editor. find the line recipe.hooks.linking.postlink.1.pattern.windows=cmd /c copy "{build.system.path}/energia/energia_pm4fg.rov.xs" "{build.path}" an delete it. You should now be able to compile. Robert

    MSP430 Board Definitions 1.0.5 Breaks Serial

    Which MSP430 board are you using.
  10. Currently we do not have the internal temperature sensor ADC channel exposed but I think it is a good idea to get that enabled. Would you please be so kind to submit a feature request here? https://github.com/energia/msp432r-core/issues Thanks, Robert

    G2553 UART issues

    Couple questions: Was this always the case or did it function correctly at some point? Which version of the Energia IDE and which version of the MSP430 packages do you have installed? Can you post the Sketch you have used to send data? Robert

    MSP432 Black suddenly gone from Energia

    This board is indeed obsoleted. It was replaced by the RED board many years ago. The TI-RTOS version it was based on no longer receives updates. Hence, it was time to retire this. If you still like access to this board then do the following: Open Energia's preferences (File->Preferences or on macOS Energia->Preferences) Located "Additional Boards Manager URLs" and paste the following link into that field: https://energia.nu/packages/package_msp432_black_index.json Go to the board manager and you should see the black board appear again. Good luck with your Robot project. Robert

    i2c communication not working on msp430fr5969 rev 2.0

    I just ran a quick test with the Sketch below. This is using MSP430 core version 1.0.3. Note that as per pinmap I2C lines, by default, are on pins 9 (SCL) and 10 (SDA) http://energia.nu/pinmaps/msp-exp430fr5969/. Also make sure that you have GND connected from the device to the LaunchPad. What type of device are you trying to talk to? #include <Wire.h> void setup() { Wire.begin(); // join i2c bus (address optional for master) Serial.begin(115200); // start serial for output } uint16_t x = 0; void loop() { /* Read from device #2 */ Wire.requestFrom(2, 6); // request 6 bytes from slave device #2 while(Wire.available()) // slave may send less than requested { char c = Wire.read(); // receive a byte as character Serial.print(c); // print the character } Serial.println(); /* Write to device #2 */ Wire.beginTransmission(2); // transmit to device #2 Wire.write("x is "); // sends five bytes Wire.write(x); // sends one byte Wire.endTransmission(); // stop transmitting x++; delay(500); }

    Energia Library in CCS

    You can. Simply #include the library you wish to use in your Sketch. All libraries that are in the Energia library folder can be used. To find out where your Energia libraries are stored, go to the Energia preferences and note the "Sketchbook location" directory. The libraries are stored in the Sketchbook Location folder / libraries. Robert
