  1. I'm new to micro-controller programming and am seeking some help. I'm using the MSP-EXP430G2553 Launchpad. Following examples from online contributors I have inserted the following as the first line of code: // WDTCTL = WDTPW + WDTHOLD; // Stop WDT However, when this is enabled it prevents serial monitoring and interrupts from working. I don't know if it is relevant but the uart jumpers are set to HW.
  2. Hi there Currently I am using the Serial1 pin to I2C for the LCD. so, I can't use the Serial1 in the CC3200EMT (multitasking).When I see the source code of Board_init.c, there is Board_openUART() function which seems to initiate the PIN. I need to change the pin 3 and 4 to 7 and 8. but even I changed the source code, it wasn't able to apply them. It seems the complier linking the binaries directly. Did you already announce the procedure how to recreate libraries? or Can you suggest other ways? //MAP_PinTypeUART(PIN_03, PIN_MODE_7); MAP_PinTypeUART(PIN_07, PIN_MODE_5); //MAP_PinTypeUART(PIN_04, PIN_MODE_7); MAP_PinTypeUART(PIN_08, PIN_MODE_5);
  3. Can anyone help on this issue please ? On Ubuntu 14.04 64 bit, I am unable to get the serial port to work with Energia 16 and MSP430G2. I have exactly followed the install instructions for Linux : http://energia.nu/guide/guide_linux/ including setting udev rules. The MSP430G2 can be programmed ok however any attempt to open the serial port monitor causes Energia to hang up/freeze. FYI, I also have an Arduino board with the latest Arduino IDE which has no problems with serial output on this same evironment (and setting that up was a breeze). It's a pity that getting Energia to work on Linux is so hard. I have seen previous postings on this issue suggest a custom build of the cdc_acm driver; is that really necessary given Arduino works fine ? Below is the output of dmesg: [42439.494174] usb 1-1.2: new full-speed USB device number 4 using ehci-pci [42439.609479] usb 1-1.2: New USB device found, idVendor=0451, idProduct=f432 [42439.609484] usb 1-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [42439.609487] usb 1-1.2: Product: Texas Instruments MSP-FET430UIF [42439.609489] usb 1-1.2: Manufacturer: Texas Instruments [42439.609491] usb 1-1.2: SerialNumber: E7FF4D53F4181B50 [42449.663054] hid-generic 0003:0451:F432.0004: usb_submit_urb(ctrl) failed: -1 [42449.663078] hid-generic 0003:0451:F432.0004: timeout initializing reports [42449.663362] hid-generic 0003:0451:F432.0004: hiddev0,hidraw3: USB HID v1.01 Device [Texas Instruments Texas Instruments MSP-FET430UIF] on usb-0000:00:1a.0-1.2/input1 [42449.758556] cdc_acm 1-1.2:1.0: This device cannot do calls on its own.

  4. I am trying to upload a sketch but am unable to, as there is no way to set the port, as the Serial Port option is greyed out in the Tools menu. I am running OSX 10.9.5, my device (CC3200 LaunchPad) is being recognised on the USB bus (see details below). USB <-> JTAG/SWD: Product ID: 0xc32a Vendor ID: 0x0451 (Texas Instruments) Version: 5.00 Serial Number: cc3200 Speed: Up to 12 Mb/sec Manufacturer: FTDI Location ID: 0xfa130000 / 6 Current Available (mA): 500 Current Required (mA): 500 I have tried installing the VCP drivers from FTDI. I am using the latest version of Energia. Any other suggestions?
  5. hello i am using TM4c123GXL. i am facing problem to Read the string on the Serial Port. Please give me idea ..how i can get my goal.... the function Serial.Read() return the integer .... i want to get the string ...how is this possible Thank you...
  6. QUESTION: Any pointers as to why the Serial Port is grayed out on 64-bit Centos 6? In the next post, is my detailed installation log (with errors) - but here is a quick summary: I determined that I'm on 64-bit X86 Centos 6. I checked to see if the libusb drivers are installed. I checked to see what version of Java is installed. I checked to see how Java is configured. I downloaded the Energia Linux binary tarball (energia-0101E0009-linux.tgz) I untarred the Energia tarball to create an energia-0101E0009 directory. I ran the energia application. I set the board to msp430g2553 (16MHz) I failed at selecting the serial port because the selection was grayed out. I ran the default "Blink" procedure, which caused the board LEDs to blink. I modified the "Blink" procedure, and tested that it was working. I tried to open the Energia Serial Monitor - but failed. Googling for how to solve this problem, I added a udev file & rebooted. Googling further, I added user1 to the various groups and rebooted. Googling further, I obtained and compiled librxtx-master. I installed the EPEL rxtx using "sudo yum install rxtx". Yet, the serial port is still grayed out! Q: How do I diagnose WHY the MSP430 serial port is grayed out? Note: Searching this forum came up with this - but it doesn't seem to apply as it's on Windows: - serial port grayed out in IDE ver E0009
