I'm using crossworks v2, and msp430fg4618 and trying to output a 256 word waveform out of DAC12_1 using dma. I'm triggering the dma transfer using timerA and passing the data directly through to the DAC rather than triggering the dac latch with a timer. i generate an IRQ after the 256 samples have been DMA transferred. This method seems to do what i want with one exception - i can't get the correc...

All, I've just uploaded Butterfly BASIC for the MSP430 to our website--it wasn't doing anybody eny good languishing on my hard disk. Butterfly BASIC is a small BASIC interpreter for the MSP430 which stores its program in FLASH and uses very little RAM. It's released under the GPL, and compiles with CrossWorks for MSP430 and runs on a selection of boards, e.g. the SoftBaugh ES449 and DIr16

The CrossWorks IDE comes with demo code for SoftBaugh board to record/playback audio stored in Flash, using 2 DMA channels - one for ADC, one for DAC. > And is it possible to use DMA for emulating 16-bit I/O registers or a 16-bit UART > (Rx/Tx irq only when two bytes are received/transmitted)?

Hello all! I am trying to include a text file (about 10kB) into a project. I want this file to be as is in the MSP flash and read it out when needed. It contains a lot of special characters that I would need to escape when including as a string. Is there a way to include the file into the project as is? I tried to add it to the project and of course it produced a lot of errors as the

Hello, we're using the F149, programmed in C with Crossworks, communicating=20 via a 115kBd RS232 with the PC. We implemented a very simple "XOR" CRC, which checks the ASCII=20 formatted data and is transmitted at the end of the data string, also=20 ASCII-formatted. I tried to check, if the CRC calculation is correct, maybe, I did it=20 a bit stupid. code (the ASCII formatting is cor...

well im trying to do simple float operations, but i get crazy results...a few examples...i have an accelerometer i want to use as a tiltsensor (2-axis) this simple code calculate the values: float pitch, roll; pitch = 180*asinf(Ax/807); // 807 = 1g roll = 180*asinf(Ay/807); when i do this, i get -23040.000000 when Ax and Ay is close to 0 (+/- 100) whats wrong? according to crossworks

Hi all you CrossWorks 430 users ... What's the fastest way to create a new project that is substantially identical to an existing one? E.g. I have a solution (t40) with one project (t40). I'd like to add another project (t41) to this solution. The Project System Help files talks mainly about File | New | New Project ..., but I don't want to create the t41 project from scratch, as it is sub

Is there a way to re-attach the debugger to the MSP430 without reset? My device is running (JTAG not connected), I connect the JTAG adapter, start crossowrks and connect the FET. I choose the option "Attach debugger". Now it seems connected and I have the options break or stop available, but break has no effect and stop does a reset. Any ideas? Matthias
