Contact me for Embedded Product Design and programming I am an Embedded Engineer. I have worked with 8051, PIC, AVR, PIC24, dsPIC, PIC32, STM32, Tiva, stellaris Microcontrollers. I design embedded circuits and write programs for it in C language. If anybody needs projects to be done or needs an embedded product to be designed then you can con
Hi for all, I use EasyMx Pro for stellaris board with LM4F232 (Cortex M4) mcu, I need to read temp from 18B20, but on TFT I only have 000.0625 C, sensor in connected on PD4 port the code is // TFT module connections char TFT_DataPort at GPIO_PORTJ_DATA; sbit TFT_RST at GPIO_PORTH_DATA5_bit; sbit TFT_RS at GPIO_PORTG_DATA7_bit; sbit
hello i am using a stellaris launchpad XL package from stellarisLaunchPad_Fred library. and i am getting these dimension error while routing around the board .although the board only has the header footprints on the layer itself and the border or the dimensions are floating above the wires on top layer. 1.what does this error mean. 2.would it
Hi, I'm trying to understand TI JTAG programming protocol. I've a stellaris LM3S2965 board and I'd like to create my own programmer but I don't know what JTAG instructions (and when) I have to send. Someone told me it's documented but I don't find anything on the web. Do someone know where I can find it? Thanks.
Hi, I have an Altera board with a Cyclone 4 FPGA and a stellaris LM3S2965 Evaluation Board. I want the FPGA to know when the computer is sending data to the microcontroller to program it. I was trying to detect a transition on tck on the JTAG port of the stellaris board but it seems there are transitions even when nothing is happening. Can someone
Hi guys, I am new on this forum. About programming ARM stellaris LM4F120H5QR in assembling, knows someone tutorials or example project ? Thank you.
I am trying to interface MQ7 (CO) with TI stellaris launchpad (operating voltage is 3.3V) but according to datasheet MQ7 requires Vh= 5v and Vl=1.4v. So, how to interface MQ gas sensors with 3.3v microcontroller????
I would like to attempt to create something like the XIM3 but with just a stellaris. For those who don't know what the XIM3 is: it is bassically a device that sits between your xbox controller en the xbox 360, letting the security signals pass trough freely whilst altering the other data signals (input signals). I have attempted to find out h
Hi all, can anyone help me in making pic16f877a communicate with a PC via the LAN switch ? any one worked on "stellaris? Serial-to-Ethernet Reference Design Kit" can help me ?
Hello all, I am making Autonomous Quad. I am programming my IMU using ADXL335 -3 Axis analog Accelerometer & L3G4200D 3-axis digital Gyro. I am using ARM Cortex M4F based TI's stellaris launchpad LM4F120XL. I've a problem while implementing IMU. Here is my algorithm of IMU... By ADC I am getting reading of accelerometer in Dx, Dy & Dz.
HI, I am in need of very tiny RGB led, the same one seen on a stellaris launchpad. Can any one give me the link from which I could purchase the same led... Searched a lot in alibaba but couldn;t find the exact one...
Hello, I am trying to interface MMA8451Q Accelerometer with My stellaris launchpad LM4F120H5QR, it uses I2C interfacing. My code is correct because it works with the other sensor which uses the I2C interfacing. But that same code is not working with MMa8451Q. Is there anyone who has an experience to work with MMA8451Q ?? ( www.nex-r

Hello friends,,,, I am using ARM Cortex stellaris Board,it is running perfectly in the morning,but after some time when i am going to do programming,then my device LM3s9b95 is not detected in the microbootloader. my reset switch is wrking perfectly but my device is not detected in the bootloader. then i use programming u
Hello, i'm using Texas stellaris LM3S9B96. First I am designing the board, so I have to do all the wires between all components and the microcontroller, so when software will be developed everything will be ok. I would like to use a SDRAM and a CPLD at the same time. The idea is to use address/data bus for both these components, in order to save
Hello everyone, I am using stellaris lm4f120 launchpad in my project. That board has USB B Type Device port. I want to convert that port into Host port. Is there any way to do it?? I know about the conversion circuit of USB B to USB A for connecting the devices but I've no knowledge to convert the Device port into the Host port ! :( I wa
I wish to use TI's TPS63020 as the voltage regulator in a portable circuit powered by a LIPO battery (single cell 2.5V-4.2V) to power up the LM4F120H5QR (ARM M4) . (I assume the fuly charged LIPO has 4.2 and tolarable discharge is 2.5V) At voltages above the 3.4 the this IC works in Bu
Hello Everyone, I've a question that can I program ARM Cortex M4F processor based controller using MATLAB?? If YES then how? (why I want to program it with MATLAB is not important, I just want to know it because I am curious to know it whether it is possible or not?) I am using stellaris Launchpad LM4F120 Series
Today i installed the Keil IDE for stellaris EK-LM4F120XL Launch Pad, But i couldn't get it running due to some linking problems. I couldn't link the library from stellarisWare folder required for the launchpad. somebody please suggest something
I want to create a PCB using my stellaris LM3S3748 . I jurst want a PCB breakput board board diagram in eagle, Altium or some stranded design suite so i can program it using a JTAG and use its pins for a purpose since they are taken out. Is there anyone who has done this before so i can have the Break out PCB board files? Im willing to gi
