Hi, I'm trying to use an old stellaris launchpad board as a datalogger to an SD card for logging data from an accelerometer. I've already built such a project on the arduino hardware but best I can do is one reading per 2ms and I want to get it logging faster... at least 1 reading every 500us. So I thought I would port it onto the the launchpad boards I had kicking around. Straight up the SD card didn't work trying to use SPI(3) as the underlying SPI bus and I have downloaded and tried about 6 different sd card libraries but got nowhere. What I then did was go back to first princip

This is a very simple enc28j60 library created by Renato Aloi for atmega modifed by me for MSP430G2553 and MSP430F5529 Please, check my latest master fork from Renato Aloi newMods branch or download directly v0.4.2: EtherEncLib-0.4.2.zip fix CS, fix examples, disable debug from tcpstack EtherEncLib-0.4.zip only harware SPI version (MSP430G2553 and MSP430F5529 tested) EtherEncLib_v03.zip - hard/soft spi version EtherEncLib_v2.zip - hardware spi version EtherEncLib_v01.zip - softspi version v03: selectable hardware/software spi all definitions moved to EtherEncLib.h lines 1

Hello, im barely new in ARM programming. What i want to do is to run four independent PWM channels to manage my things. I wrote some code and as i supposed it didint work. In debug process i checked registers and it seems to be ok. Load and match values are corerct so i think error is somewhere in timers configuration. Can someone help me out ? Thanks in advance for reply. Here is my code that i ran on my launchpad. #define PART_LM4F120H5QR 1 #include <inc/hw_types.h> #include <inc/hw_memmap.h> #include <driverlib/sysctl.h> #include <driverlib/gpio.h> #include &l

Hi, guys. I am a beginner in Stellaris microcontroller programming. I try to generate a delay of 1 sec (1 sec - led ON, 1 sec - led OFF). I have selected the timer0A - 16 bits. Delay - 1sec. Frequency = 4 MHz T = 1 / 4Mhz = 250 nsec. So, to generate a delay of 1 sec : 1.000.000.000 nsec / 250 nsec = 4.000.000 4.000.000 = 62.500 * 64; But i think in my code i must set another bit, i dont know if it is correct, his name "main interrupt". Here is my code :

Hi! Is there a reference design for board using LM4F120H5QR in case I want to create a custom board based on this chip? (Stellaris Launchpad is quite big for my project). Ideally in Eagle format. Or at least is there a library that contains LM4F120H5QR part so I can create such reference design?
