thomasss posted a topic in GeneralHi Everyone, I have been looking for about an hour online and haven't been able to find the answers to these questions. - Can I use floating point with the msp4302553 ? the watch expression on CCS don't seems to like floating point for sure. - Can I use math.h to do trigonometry calculus on the msp430g2553 ? Let me tell you guys what I am trying to do so that it is more clear: I am scanning a signal with an ADC. I would like to do an atan() on the signal and output the signal with an DAC. Right now I can scan the signal and send it to the DAC. This works well. But I can't get the trigonometric conversion to work. Is it possible to do it? And if yes could I get a little help from you guys ? Thanks in advance for your help. Thomas PS: I saw about these Qmath functions that came out recently but couldn't get it to work either http://www.ti.com/tool/MSP430-iqmathLIB?DCMP=ep-mcu-msp-iqmath-en&HQS=ep-mcu-msp-iqmath-pr-sw2-en
