Hi Both stellaris and LPC1xxx are equipped with Cortex M3 I can advice you to work with STM32 (also Cortex M3 ) because he have more application note and you can find more project and source code on the net And this is a good step to start with All the best Bobi The microcontroller specialist [/
stellaris bootloader in application I am using stellaris LM3S600 on keil uv4. I want to impliment bootloader in my application. the starting address of the application is 800. but how to insert the bootloader code in my application and which part to be include. Thanx, Embed_v
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
Just ordered the stellaris ARM LM4f eval. board from TI. While it wont arrives im interested to know about the arquitecture and programming of the refered mcu. My knowledge in mcu's resumes to pic and picbasic. Basic knowledge in C programming but not in arm / mcu enviroment. Googled the subject triyng to find codes and projects already built i

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

Hi, if you can program a TMS 320, an ARM7 should be easy! The LPC2000 and other ARM7/ARM9 are very easy to program via JTAG using something like e.g. J-Link from Segger. Which tool chain are you looking for, free tools, low cost tools oder professional (higher cost) tools? lists so
The power consumption of the LM3s is higher then the STM 32 since it use the 250nm process and the STM32 use 90nm process where did you get your information of ST using a 90 nm Flash process? Too much science fiction! In deed ST is using a smaller process than Luminary but the difference is only 1 generat
If you want to build something that makes future extensions easy and you get it at a very reasonable price, you should look at the ARM Cortex-M3 devices from different suppliers such as ST, TI, NXP Some information can be found here: check out the LPC1768 and here:
Hi friends i was doing a research about stellaris LM3S9B96 this is a very good device to use in my new project here. But there is alot of compilers and jtag debuggers. Any has and advice about jtag debuggers if any very good than other. And about compilers too. I made this generic, i am open to any compiler include GCC that i don´t know if it is
check stellaris micro. now texas instruments, hope helps, //a
The pdf of your schematic is too coarse to be readable - what I figured out is a mux and an adc controlled by the PP. The stellaris? Family of ARM? Cortex™-M3 - LM3S2608 from TI supports 8 PWM; Freescale Semiconductor MAC7101 supports 16, STMicroelectronics STM32F103RC but these are all ARM devices. Infineon has a 8051 device - C509-L but I'
hi, i am using the board EK-LM3S9B92-B. I was using it with the demos and all was fine. I made my own proyect with a realtime tick of 1ms. All works well. I begun to learn about FREE-RTOS. I download it. Read about it. And i comment from the example all about a display because it was for other board and micro. Well i made one task to test it. I
hiiii i want to calculate the prescaler value for the following 16-bit timers to generate a 1us tick and the controller is running at 50mhz. i am using LM3S811 stellaris uc. in the datasheet it explain like this ... but i dnt understand how the Mx time to be calculated.... All values assume a 50-MHz clock with Tc=20 ns (cloc
I read safe RTOS user guide. SafeRTOS is inbuilt in stellaris MCU by TI. I have three task which should work sequential .After i finished my first task ,i want to give signal to second task to start and then second task give signal to third. .I dont know how can i use queue concept to just communicate signal. Can any one give me some information

We need some clarifications in IAR IDE 6.21 (lm3s9b96), 1)How to enable the option for Profiling as we could not see any plugins in Project options (But this option is available in version 5.41) 2)We are facing issues when we try to compile the given example applications (C:\Program Files\IAR Systems\Embedded Workbench 6.0 Evaluation\arm\exam
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! 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
Hi I am using codesourcery for TI stellaris Cortex-M3. I need all my hex files generated by the linker to be 64K size regardless of the original size. in other words I need the compiler/linker to pad the generated file to 64K with 0xFF Is this possible?

I have not worked on porting the lwip to a controller, but i have worked on lwip with stellaris line of controllers. You will need all the relevant source files for lwip. You need to include them in your project and then see if the build is successful. To configure the lwip specifically to your needs, you will need to change the lwipopts.h file,
If you've previously used Microchip PICs, you could use the PIC32. Although it's not based on the ARM architecture, I wouldn't call it weak. This might be an easier approach for you. However, if all is new to you, I would suggest you go with the ARM controllers. I haven't used the ARM controllers myself, so I can't recommend any. However, besides
Which microcontroller are you talking about? Version 7.10 has the "PICOLO" DSP and the stellaris microcontroller. Labcenter Electronics - Proteus VSM - SPICE Simulator/Debugger for ARM Cortex M3 Labcenter Electronics - Latest Release Hope this help
You should first decide which family you are going to use. For this you can choose depending on what you can find available and reading online about the features, advantages, disadvantages, etc of the families. As I personally do not use or program ARM controllers, I can not comment on this, but here are a few you can look at:
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

If you have a board with that processor on (or almost any other uC), you will need separate hardware like a JTAG or ISP programmer to download your code to the uC or flashmem or to debug your programming. Something like this for example: You can also get a development / evaluation board which already contain
