Hi, I'm building a system which requires a DAC. I would like to ask how would you program a DAC using Code Composer Studio and Grace. The DAC I've got is the AD5320, SPI mode. One thing I've noticed on Grace is that it doesn't have the settings for the synchronization signal. Thank you.

Hi, I'm a student working on building a pulse oximeter, making use of a msp430 LaunchPad. I'm trying to implement a LED drive circuit right now, but it doesn't work as expected. I've attached the diagram, which is taken from the TI paper A Single Chip Pulse Oximeter Design Using MSP430. (Unable to link as I'm new here) Connecting a 3V input to the emitter pins of the pnp transistors, I will not be able to get either LED on at all. Removing the voltage at the emitter pins of pnp transistors, and connecting pin 5 of DAC to a voltage of above 3V causes the infra red LED to light up. Red L
