  1. Hello, I am looking for a working Eagle library for the CC1310F64RHBT. I am not experienced with creating .lbr files for Eagle, but after some googling I have produced a rough one which is based on a conversion from the Ultra Librarian .bxl format. If anyone has a working library that they already use, it would be super helpful if they could share it with me. Taking a look at the library attached below which I have produced and confirming that the SMD footprint will work would be super helpful. Thanks, Cameron CC1310F64RHB.lbr
  2. I started learning TIVA C launchPad from past 15 days only . I am watching youtube videos. and refering datasheet. I wrote code in DRM style ,ie. direct register assignment method as shown in videos. I know little only about ADC , timer as I used these modules only. I want to learn API style coding using tivaware. How do I start..? there are many doc and videos that talks about how to install tivaware, CCS or IAR workbench. there is pdf by TI -> ' TivaWare
  3. Hello Guys, Iam starting to learn embedded systems with Tiva C board. I have issue in understanding simple code below this is part of the code input = GPIOPinRead(GPIO_PORTF_BASE, GPIO_PIN_4); GPIOPinWrite(GPIO_PORTF_BASE, GPIO_PIN_1 , input); PIN4 connected to switch and pin connected to led. It shall take the switch value and show it on the led but it doesn't work. Someone suggested to write the same code with the below if condition and it worked but I don't understand why the above code doesn't work. if(GPIOPinRead(GPIO_PORTF_BASE, GPIO_PIN_4 ) == GPIO_PIN_4) { GPIOPinWrite(GPIO_PORTF_BASE, GPIO_PIN_1 , GPIO_PIN_1 ); } else { GPIOPinWrite(GPIO_PORTF_BASE, GPIO_PIN_1 , 0 ); } Appreciate if you can clarify this to me. Thanks
  4. A totally new MSP on the way. I assume a new device rather than just a new LaunchPad, although the video focuses on LaunchPads.
  5. Hello all, I have few concepts which I need to clear! Please provide your important experience and knowledge. I keep on reading different controllers with different ratings of flash memory and SRAM. MSP has FRAM. Queries; 1. Usually flash memory is usually much larger than SRAM, because of cheaper price? 2. I know that prog is stored in flash and variables in SRAM. But the variable can be stored in flash also. right? 3. I know that FRAM is faster, less power consuming, longer life than flash.. Only MSP has this FRAM technology right? I know that most of the ARM controllers today have modified Harvard architecture with separate data and instruction cache and separate data and instruction buses. Data and instructions in the same memory. I want to clear some basic concepts. thanks a lot. Vin255
  6. I guess it'll be a while until someone like TI manufacturers one and sticks it on a Launchpad, but ARM have announced the M7 which will be above the M4 in the microcontroller range. http://arm.com/products/processors/cortex-m/cortex-m7-processor.php
  7. WS2812 driver for Tiva is available here
  8. Hello friends, I just now got the stellaris launchpad to have hands on experience with ARM architecture. I have installed the driverlib and I can blink the LEDs through the APIs. The driverlib makes it easy to program the stellaris but with these APIs we cannot understand how the registers are programmed even when we look at the definitions of the APIs. These APIs are specific to a particular family. Thus, I wont be able to understand the ARM architecture. I request you all to please guide me regarding this problem. It would be great if I could find online training material with examples of stellaris, especially without the APIs so that internal complex architecture of ARM (cortex M4F) can be understood. Thanks & Regards Vin255
  9. Hi all. My name is Dragu Mircea and I am a beginner in ARM processors. I have seen all tutorials on youtube about Tiva C Stellaris posted by Miro Samek and I have an issue about Lesson 5 : Preprocessor and volatile. At minute 7 : 35 Mr. Miro Samek add a header file - #include"lm4f120h5qr.h". When I try to do the same thing this header file is missing (see the the attachments). Thank you. With respect Mircea.
  10. OK, I'm pretty new to the BBB and my background is in programming not electronics. I would really like to setup the BBB as a robotic arm controller. The arm I'm looking at is the Lynxmotion AL5D 4 Degrees of Freedom Robotic Arm. http://www.robotshop.com/en/lynxmotion-al5d-robot-arm-combo-kit-4-dof.html#Multimedia Is the BBB capable of controlling this 4-axis robot? I would assume I need a cape to do this but can't determine if an existing one would work. Any guidance would be appreciated.
  11. Hi, I have recently started to work with ARM. I have read a bit about it but, unfortunately, I have not ever been successful in implementing my code in practice. When I connect my board to the USB port of my PC an error message says: “USB device is not recognized.” Have you ever faced this problem? Do you know how it can be solved? It would be so grateful if you could guide me in this regard. Thank you veryyy much in advance, Hossein Amooie
  12. Hy for all forum members! I want to show you a newly developed ARM device for which we raise funds (for the prototype, and manufacturing) Some words about the AshimaCore : AshimaCore The AshimaCore is designed to be a very flexible, programmable inertial measurement unit - with a whole bunch of onboard computing capability. You don't need any propriety tools to program it - we recommend gcc, gmake, and dfu-util - just plug it in to your labtop via usb and you're ready to hack! This isn't Arduino, it's a far more powerful embedded development tool. We've packaged the board in a tiny footprint, ideal for a range of projects from robotics to avionics, motion logging, and home-made 3D controllers. We've also made the board easily plug-compatible with wifi and radio communications via XBee, and ready to drive a wide variety of motors, servos, or pretty much anything your project needs. The board is "best in class" being built around the powerful 32 bit, 168 MHz ARM Cortex-M4F embedded processor with floating point and the incredible Invensense MPU-9150 IMU. The board has a range of interface options (I2C, SPI, USART, PWM), is XBee / WiFi and GPS-ready, and includes a micro-SD slot. The board is designed for avionics packages, but would make a great choice for a wide range of hobby, school/university, research, and development projects. More about the project : http://www.indiegogo.com/projects/ashimacore-an-embedded-arm-imu-sense-and-control-board Please visit the project,and after share it on social networks , or even can make a donation. Thanks
  13. Hi everyone! I'm waiting for my Stellaris boards to ship, and they won't be here until December at the earliest, so I thought maybe while I'm reading about ARM development I'd also try my hand at something a little more low level. I'm fairly comfortable with AVR development and one of the things I love about it is that you can pop a chip on a bare breadboard, add a power brick, voltage regulator, a few caps, and you've got a running "board" that you put together with your bare hands. Not that there's anything wrong with prefabbed boards like the Ardiuno or Stellaris, but there's a certain satisfaction that you get putting bits and pieces together. So I'm starting to think of possibly putting together an ARM breadboard solution. Stellaris M4 chips seem to be hard to come by so I'm probably going to either use a Stellaris M3 or one of the NXP M3 chips. One of the things the NXP has is a USB bootloader so (it looks like) I can just wire up a USB port and drop my firmware onto the chip right from my desktop with a minimum of work. I'm not sure if the Stellaris family offers something like this, I haven't dug through the datasheets extensively just yet but that's on my list of to-do's. So my question: Has anyone here tried this bare-bones approach before? I know getting a LQFP chip on a breadboard isn't going to be easy, but there are several prototyping options which would let me keep the chip itself off the breadboard and wire up everything I need with cables. I'm still going through datasheets trying to figure out exactly what other components the chip will depend on being present, but it seems to have internal oscillators and such, so I'm thinking this won't be a royal pain to put together. Anyway, apologies in advance if this doesn't belong in the Stellaris section. I'm not 100% sold on using the Stellaris chip yet, but it's in the running. This is really more of a "generic ARM" project since it's more about the hardware than the specific vendor implementation. Cheers!
