Other Parts Discussed in Thread: EK-TM4C123GXL, LMFLASHPROGRAMMER, CC3200

If you post a question asking for help with something, we almost always need to know which part you are using. So please say which part in the first question and that will save an extra back and forth exchange where we ask you which part.

Second, for many questions we also need to know which tools you are using. So if it is anything related to programming a part flash, or some problem compiling or anything else that might be remotely tool dependent, tell us which tools you are using.

So in summary, if it is not obvious from your question please provide any of the following you think is remotely relevant:

what part/rev
what tools
your own board? eval board?
crystal frequency

Ok!!
what part/rev?
Metering voltage from ADC, in fact AC voltage Vrms
what tools?
Coocox
your own board? eval board?
Stellaris EKI-LM3S6965 Evaluation KIT
crystal frequency?
Not defined yet

Beatiful!!!
So read RMS from what source? Are you another ask to measure directly Line voltage and have no knowledge of how dangerous is?

Eval lboard was provided with default clock crystal...
Not defined yet ---> not possible to answer now...
Lm3S series is NRND so it is no more available and end of life product. (not available, no spare part, not orderable) New series is TIVA supported now.
Example on old stellaris library, still supported but for short time, contain example of how to read ADC, then its your turn to evaluate RMS by math or reading from external RMS converter.
NO DETAIL ----> NO ANSWER TOO!!!
Seems university of somewhere give no knowledge and all came here asking solve what is impossible!!!

Hello Rasim,,

Was a new EK-TM4C123GXL not working or was it working and then stopped.

1. Did you check if 3.3V supply is coming properly and the VDDC pin reads 1.2V/
2. Did you check if the JTAG drivers when invoked in CCS work properly, e.g. using LMFlashProgrammer can you read the USer registers and if not then what error message do you get?

Probably, Does mcu want boot loader?

Amit Ashara over 10 years ago in reply to Rasim KILIÇ

Hello Rasimkilic1985,

No it does not. The ROM Boot Loader is invoked automatically if the flash is empty. If not then the application code in the Flash is invoked.

Hi Amit,

The 3.3 V from power supply is coming properly but I can't read 1.2 V from VDDC pin. What should i do ?

Thanks,
Rasim

Hello Rasimkilic1985,

The VDDC pin comes on a probe via in the LaumchPad. Are you saying that the probe point does not show ~1.2V or you are not able to locate it?

Every thing is ok :D is problem solved.

I changed the MCU.

It is failed, I did not understand that how is it?

Amit Ashara over 10 years ago in reply to Rasim KILIÇ

TI__Guru**** 244380 points

Hello Rasimkilic1985,

Make sure that you document the steps this time so that if the MCU fails we can have the Root Cause

Hello, Why acceleration sensor and temperature sensor board cc3200 launpad inactive, while running the program it results x = 0, y = 0, z = 0 and the temperature sensor to output 2, 45 * C
Please help me!

Board used cc3200 launchers.

Perhaps - just a few lines of your code may assist - don't you think?

Unguided posters - left to their own devices - makes (great) sense indeed!

Hello cb1

Looks, like CC3200 found its way to TM4Cx Forum

Hi Amit,

Indeed - perhaps (more) notable - Ms. Cozart's, "Info to Provide" appears, "Kicked far to the curb!" (although we are graced w/several variable values - surely, "Good that.")

Poster appears to have well searched for this thread - and then (avoided) many of its pleadings - go figure...
