  1. Here is a video of the music player in action: The code has the following functionality: Initilise the FAT16 filesystem from an SD card in a single command - ThinFAT_Init(); Open Files on an SD card and allow you to test each filename with a callback Index Files by useing the same command as to open them with a callback returns data on if the filestream is active returns data on how far the file has been read through callback for when end of the file is reached Open Folders on an SD card - Untested and limitations: uses 54 bytes of ram approx dosen't support fragmented files reads file end

    Ethernet Booster Pack

    [EDIT] The newest version of this BP is here [EDIT] This project is finished Available in the 43oh Store. This is still in it's early phase, so I need your input. Here are some specs so far: 1. WIZnet's W5200 Ethernet controller chip (W5100 or W5300 is an option.) 2. MagJack 3. LDO + power header 4. Opto isolators (2 or more) + output header 5. Input/output header for switches/keypad/display 6. DIP or SMD MSP430G I have decided to use W5200 because... "W5200 chip is a Hardwired TCP/IP embedded Ethernet controller that enables easier internet connection for embedded systems using SPI (S

  3. Just a small thing I've been playing with, has six microswitches and a pushbutton to latch in the instructions. Four microswitches are connected to the lower nibble of port 2, one on bit7 of port 2, one on bit 4 of port 1, and the pushbutton is on bit 6 of port 2. Available instructions are (CMD bit high): [*:204z8i3q]0x0 (NIBBLE = x)Toggle backlight [*:204z8i3q]0x9 (NIBBLE = 1) Move the addr pointer back one char [*:204z8i3q]0x9 (NIBBLE = 0) Backspace [*:204z8i3q]0xA (NIBBLE = 1) Secondary font set (rearranged ASCII) - to be used with my external PS/2 keyboard controller [*:204z

  4. I'd most certainly as well be interested in byte to byte write support. Let us know what you find out! Regarding memory space, the new launchpads ship with the G2553 which has 16KB of flash memory space. Considering this is becoming a very common value line chip I wouldn't worry too much about the 2kb msp430s. Overall, i'd just be nice to get something to work =)

  9. I got the DHT11 sensors from SunTek today and wrote some C code to read it. This uses TimerA for accurate time measurement, and polling to allow use on any pin. The internal pullup resistor is used, so an external one is not needed. A six byte array passed to read_dht() will be filled with the start bit, 4 data bytes, and the checksum. Return is 0 for success, or a negative value for failure. This code can run at 1 MHz or higher. The DHT11 seems to need about 300 ms between readings, less time will result in the sensor sometimes being non-responsive. The fractional bytes are always 0 for the
