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, 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?

I am now trying to start the Touch screen on the TFT display. it has two analog input and two drive output to the touch screen The analog input is connected to the PORTB(PB4:XL,PB5:YD) Drive A = P
Hello! The most difficult about giving you advice here is that we don't know what you are planning to do. From my point of view, MSP430 is a low power device and it has been designed to drive a whole system from a single chip. Therefore, if you need external memory, probably you should use another device, possibly stellaris if you want to sti
Hello! I use ARM processors, and the first board I bought was a TI board with a stellaris MCU. About 70$. The advantage is that you don't need an emulator, the emulator is on board, so you just have to plug the board with a USB cable and you're on! Probably other makers also have boards with integrated emulator, so you should consider this issue i

Hello! If STM32 is not an absolute requirement, you may consider buying a stellaris board (or another maker that provides on-board debug tools). In this case, there is an on-board emulation tool, you just need an USB cable. I just bought one for about 60 USD with a tiny OLED display (I have started a project requiring ethernet so the display
The stellaris M3 JTAG inputs have pull-ups with a specified resistance range TDO is a 2mA drive strength output. It don't see a problem with 27 ohm series resistors it also doesn't change the signal speed much as the output impedance will be considerably higher.
Hello colleagues, I'm using TI's stellaris LM3S1621 MCU. Tell me please if it is possible to start DMA transaction from external interrupt (triggered from any GPIO)? For example I'd like to take one byte from PORTA and save it in external SDRAM. Besides this frequency of starting pulses is very big so interrupt mechanism is not applicable. Thank
