  1. Thanks, I see that the C2000 LaunchPads are supported for Windows and Linux. Does this imply that there is a problem with Mac desktop support? Bob Rice
  2. What is the current level of support for the TMS320F-28377S? I saw a core for C2000 LaunchPad XL on GitHub so I went ahead to obtain a board and upgraded to Energia 17. The board is not listed in the menu although the Serial Monitor receives analog data from pre-loaded demo program. Thanks, Bob Rice
  3. There are a couple of bugs in some of the TI Connected LaunchPad SPI pinout documentation. You will be able to figure it out by cross-referencing documents. Bob Rice
  4. Update, I didn't see any replies to my problem so I gave up on the Ethernet connection for awhile, but went back to try again after upgrading to Energia release 14. Unlike release 13, I had no problems upgrading to release 14, no performance problem, but the upgrade didn't seem to fix any bugs for me either. I still have to request a baud rate of 172800 to get 115200 for the LaunchPad. So I decided to try using the EthernetUDP library since that wold be better for my real-time application anyway. Again I came close to getting it working but no cigar! Seems that I can read datagrams OK but I can only write the first one. On each suceeding set of calls to: Udp.beginPacket Udp.write Udp.endPacket the Connected LaunchPad resends the first packet and does not send the new packets. Has anyone else reported this problem? Am I using the library wrong? Thanks, Bob Rice
  5. Hi, I have been using the MSP430LPCDC 1.0.3b for some time but now it has stopped working for me. It was working on 10.10.1 but now is not recognizing either my Launchpad or my Connected Launchpad - no device files are created. Reinstalling it didn't help. It seemed to stop working when I updated my Prolific PL2303 and FTDI device drivers. I don't know how to debug this problem. There is very little documentation on this driver or even how the VCP connections work. Any suggestions? Bob Rice
  6. Hi, I have a Mac desktop app that connects to a Connected Launchpad via USB serial. I decided to try to add ethernet port connection. I got tantalizing close but no cigar! I've been stuck on this for a week now so I need help. I had no problems adding the Ethernet.h library except for something very weird trying to do a conditional import. I have been using directives to compile for either the LaunchPad or the Connected LaunchPad: #ifdef PART_TM4C1294NCPDT // Connected LaunchPad #include "Ethernet.h" #elif defined( PART_LM4F120H5QR ) // LaunchPad #endif This seems to have been working, but it doesn't work for the above code. I have to comment out the #include "Ethernet.h" to compile for the EX-TM4C123GXL, but this is only a minor inconvenience. I set up a Telnet socket and was able to connect to it using the Unix Telnet program. I could connect, disconnect and reconnect, but the server does not recognize the disconnection. The client.connected() function continues to return true so I only get my sign message with the first connection. Still, I thought I was ready to go so I added NSStream to my app. It could connect and exchange a few messages before giving me a Stream Code 54: The operation couldnz6MainEthernet.ino
  7. Will the Energia team be supporting the new Tiva C Series LaunchPad? I understand that TI has already deprecated the Stellaris LaunchPad in favor of the new Tiva C Series. I am trying to upgrade from a PIC
  8. My app currently uses the Digilent "chipKit" Uno32 board and a Mac host. I am trying to port it to a new Tiva C Series LaunchPad that I just received. I get the following errors from the library: /Applications/Energia.app/Contents/Resources/Java/hardware/tools/lm4f/bin/../lib/gcc/arm-none-eabi/4.7.1/../../../../arm-none-eabi/lib/thumb/armv7e-m/fpu/fpv4-sp-d16/libc.a(lib_a-writer.o): In function `_write_r': /Users/rwessels/yagarto/newlib-build/arm-none-eabi/thumb/armv7e-m/fpu/fpv4-sp-d16/newlib/libc/reent/../../../../../../../../../newlib-1.20.0/newlib/libc/reent/writer.c:58: undefined reference to `_write' /Applications/Energia.app/Contents/Resources/Java/hardware/tools/lm4f/bin/../lib/gcc/arm-none-eabi/4.7.1/../../../../arm-none-eabi/lib/thumb/armv7e-m/fpu/fpv4-sp-d16/libc.a(lib_a-closer.o): In function `_close_r': /Users/rwessels/yagarto/newlib-build/arm-none-eabi/thumb/armv7e-m/fpu/fpv4-sp-d16/newlib/libc/reent/../../../../../../../../../newlib-1.20.0/newlib/libc/reent/closer.c:53: undefined reference to `_close' /Applications/Energia.app/Contents/Resources/Java/hardware/tools/lm4f/bin/../lib/gcc/arm-none-eabi/4.7.1/../../../../arm-none-eabi/lib/thumb/armv7e-m/fpu/fpv4-sp-d16/libc.a(lib_a-lseekr.o): In function `_lseek_r': /Users/rwessels/yagarto/newlib-build/arm-none-eabi/thumb/armv7e-m/fpu/fpv4-sp-d16/newlib/libc/reent/../../../../../../../../../newlib-1.20.0/newlib/libc/reent/lseekr.c:58: undefined reference to `_lseek' /Applications/Energia.app/Contents/Resources/Java/hardware/tools/lm4f/bin/../lib/gcc/arm-none-eabi/4.7.1/../../../../arm-none-eabi/lib/thumb/armv7e-m/fpu/fpv4-sp-d16/libc.a(lib_a-readr.o): In function `_read_r': /Users/rwessels/yagarto/newlib-build/arm-none-eabi/thumb/armv7e-m/fpu/fpv4-sp-d16/newlib/libc/reent/../../../../../../../../../newlib-1.20.0/newlib/libc/reent/readr.c:58: undefined reference to `_read' collect2: error: ld returned 1 exit status Will there be a new release of Energia for the Tiva C Series?
