  Hello Sivanathi, Yes, floating point numbers are challenging to manipulate efficiently using microcontrollers. Two recommendations would be to scale up your floating point number into an integer (e.g. 0.12345 into 0x3039) before sending it over RF communication…

  Hi, 1. LEA is mostly used in signal processing. To calculate a RMS, using MPY32 Peripheral is better. 2. You need to use our IQmathlab. You can find functions to compute the square root and multiplication. 3. You don't need to care about how to control the…

  Hi Alexey We can do mag=real^2+img^2 refer to the MSP DSP Library : software-dl.ti.com/.../group__dsplib__transform__real.html and the sqrt you can do it with the QMATH library:: http://www.ti.com/tool/MSP-IQMATHLIB
