  Hi Stephen, I'm not familiar with these files/functions, but they may be related to the printf() or sprintf() functions. However, if you search the forum, you'll find that this isn't recommended for a MCU. There are other novel ways to get around floats…

• RE: CCS/MSP430FR6047: Use LEA for division or reciprocal

  Hello, Are you using the MSP-IQMATHLIB division with LEA? That's probably the most efficient way to perform division outside of implementing everything in assembly. I would recommend that you look for ways to eliminate or reduce the number of divisions…

  Hello Hyosung, Okay so I had some issues with the project and worked out most of them but the linking of files isn't the cleanest, so you'll have to deal with that a little. The project is attached here: TRF7970ABP_G2ET_FRL_Reader.zip To get it…

  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…
