    CC3200 parameter !

    thanks abecedarian , how I can determine my line is XCC3101GZ or XCC3200HZ ?

    CC3200 parameter !

    If you are using pre-production CC3200 Launch Pad with XCC3101GZ or XCC3200HZ, the device must not get formatted as secured I have read the above line in Uniflash userguide, but I do not know what is XCC3101GZ and XCC3200HZ? Plz help me to explain 02 notations. Thanks!

    Uart trouble in Tiva C 2.0 lib

    How I can understand about '16000000' value in below code: UARTStdioConfig(0, 115200, 16000000); Pls give me an explanation as detail as possible.

    Set Reference Voltage for ADC module

    As Datasheet tm4cg123h6pm, "The ADC operates from both the 3.3-V analog and 1.2-V digital power supplies" How to choose one of them with ADC module, If I do not choose, which voltage is default ? Thanks in advance!

    can not debug

    Thanks @@Lyon for your recommend, in my case, Board have worked, I can toggle two LEDs on pin PB0 and PB1, But when I config for pin PC4, it can not control, I also to test PC5 (close to PC4), it work perfectly. Please give me a explanation, my TM4CGH6PM was shipped from Ti's sample (free). I was doubted about this sample, can I trust in all TI's sample ?

    can not debug

    I measure voltage of VCC=3.3, VDDC =1.21 (V), I try to set digital output on pin PC4 and measure V_PC4=0.91 volt, But when I use TIva LaunchPad V_PC4=3.3 V. I hope someone explain for my issue. Thanks everyone!

    encoder interface

    So what is the best way to convert 5v to 3v3 for reading encoder purpose ? I want to read encoder exactly as possible at 3v3. Can I find a IC which can convert 5v analog to 3v3 analog? Please give me some solution! Thanks in advanced!

    encoder interface

    Hi everyone, I have a motor, its encoder's output 5VDC, I want to convert it to 3v3 VDC to interface with MCU. and I know that schmitt trigger will help eliminate noises of encoder, so I want to design a board have both functions above. Please give me the way to do this. Thanks everyone!

    can not debug

    I have done, but I can not set HIGH digital output at pin PC4, (GH6PMI), other pin is still good, where is my fail? Thanks spirilis

    can not debug

    HHi everyone, I have made a board with MCU TM4CGH6MPI (TI's sample), with 16 Mhz crystal SMD. I have connected Jtag of TIva LaunchPad and board as below: TCK -TCK TMS-TMS TDO-TDO TDI-TDI GND-GND PA0-PA0 PA1-PA1 The next time, I debugged code but It do not allow, and notify some thing 'Error connecting to the target', 'Error connecting to the target out of freqency'. Can I solve my problem? I have spend a large amount of money for this board, please help me! Thanks everyone!

    using ADC tivalaunchpad

    I'm going to use TMP101Q for reading temperature, but the document fair complex, I also can not figure out the source code to implement my project. Can you give me some solution to use this sensor? Thanks

    using ADC tivalaunchpad

    I want to read battery votage of Motobike. and measure ambient temperature, can I use any sample from Ti to make it ? How to get a accurate offset in ADC formula? Thanks @L!

    using ADC tivalaunchpad

    Hi everyone, I want to use TivaLaunchpad's ADC to read Battery voltage and tempurature with the highest accuracy possible, Please give me solutions. Thanks everyone.

    Compare TM4C123GH6PM and TM4C1233H6PMI

    yep, I wan to alternate GH6PM but I only have 3H6PM sample from Ti, is it possible? Thanks Igor!
