Forum Post: RE: Generating Sine Wave Signal from MSP430
Hi Brian, I applied first order low pass filter at the output of Msp430. Before filter I generated 100 Hz pure PWM but after filter using I am looking sawtooth on the Dewesoft screen. I used R=47 k ohm...

BTW, there are some MCUs on the market (at least some Cortex M and MCP PICs I know of) which can output a MCO signal ("Master Clock Out" a fraction of the core clock, usually up to 1/2). While this has...

As shown in the MSP430 Hardware Tools User's Guide figures 2-1 through 2-3, JTAG pin 2 should be connected if the FET tool is supplying power to the system or pin 4 if a local target power supply is...

Hi Justin, My first suggestion would be to combine everything into one big loop, that way there aren't two separate files. I think where you are running into trouble is in the if, else if, and else...
View ArticleForum Post: RE: Generating Sine Wave Signal from MSP430
Betul, You are on the right track. Couple of things - you really need a 3rd-order filter to get close to a sine-wave. The db/decade roll off of a 1st order filter is very slow and allows the...

I did exactly what you said using SPI with block-to-fixed DMA transfer and it worked beautifully! The memory savings of being able to transmit all of the data across a single pin at a much faster rate...

Hi Billy, The MSPDS tools page states that the MSP Debug Stack is officially supported on Windows 8/10 for 32- and 64-bit, and it has been tested and confirmed as such. But I understand the confusion...
View ArticleForum Post: DMA with SPI relative clock speeds
Out of curiosity, when using DMA over SPI, shouldn't the UCA/B CLK be going 4x as fast as MCLK in order to transfer the full byte in only 2 MCLK cycles? If so, how do you set the USCI clock to be 4x...

Hi Hayeon, To power the device with an external supply, remove jumper J6. The MSP432P401R has an operating range of 1.62V to 3.7V. You do not necessarily have to power the device externally in order to...
