  1. SSD1308 I2C OLED - Stellaris driver API

    hello .... will it work for tm4c123g?
  2. May be it is noise but not external.... cuz if i use internal Pulldown resistor , I am getting the same result. But If I connect it to 3.3V ....I am getting almost constant 4095 value. I have also tried using hardware avg and dither enable. When using hardware avg it is taking avg over the noise and thus giving a value between 10 to 15. But I need 0 output when connected to GND.
  3. I cant compile codes for tm4c123g anymore. My boards suddenly disappeared from board manager. Now when I want to open it, it shows the following error: Error downloading http://www.energia.nu/packages/package_index.json java.lang.RuntimeException: java.lang.Exception: Error downloading http://www.energia.nu/packages/package_index.json at cc.arduino.contributions.packages.ui.ContributionManagerUI.lambda$onUpdatePressed$0(ContributionManagerUI.java:151) at java.lang.Thread.run(Unknown Source) Caused by: java.lang.Exception: Error downloading http://www.energia.nu/packages/package_index.json at cc.arduino.contributions.DownloadableContributionsDownloader.download(DownloadableContributionsDownloader.java:113) at cc.arduino.contributions.packages.ContributionInstaller.download(ContributionInstaller.java:330) at cc.arduino.contributions.packages.ContributionInstaller.downloadIndexAndSignature(ContributionInstaller.java:305) at cc.arduino.contributions.packages.ContributionInstaller.updateIndex(ContributionInstaller.java:283) at cc.arduino.contributions.packages.ui.ContributionManagerUI.lambda$onUpdatePressed$0(ContributionManagerUI.java:147) ... 1 more Caused by: java.io.IOException: Received invalid http status code from server: 416 at cc.arduino.utils.network.FileDownloader.downloadFile(FileDownloader.java:194) at cc.arduino.utils.network.FileDownloader.download(FileDownloader.java:128) at cc.arduino.contributions.DownloadableContributionsDownloader.download(DownloadableContributionsDownloader.java:111) ... 5 more
  4. I am using TM4C123GXL launchpad ....MCU TM4C123GH6PM.... when I am trying to read ADC value using analogRead() it is fluctuating very much....even if I directly connect it to the GND pin it is giving random value between 0 to 50( 50*0.8mV = 40mV).
  5. When using analog read function, ADC never gives 0 value even when it is directly connected to the ground. But when I connect it to 3.3V it gives constant 4095 value. What is the problem?
  6. IR remote library

    Is there any IR remote library for TM4C123G? I cant find one. In energia libraries, there is one IRremote lib for MSP430. Can anyone help me to configure this? I know basics about TM4C123G timers from its datasheet.
  7. I have figured it out. Just Included TM4C123GH6PM.h which has all the register definitions. Now it is easy to create my own frequency counter using the timers. Thanks for the algorithm.
  8. Thanks for the reply. Is there any way to read/write registers directly in energia?
  9. Hello, can anyone help me to configure this library for TM4C123G launchpads ?? they have 80MHz clock speed. I want to measure upto 20MHz frequency( simple square wave with 50% duty cycle).
