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…
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…
Part Number: EVM430-F6736 Other Parts Discussed in Thread: MSP-IQMATHLIB
Dear Sirs,
We try to develop a single phase electricity meter.
We started the design based on EVM430-F6736 and Energy Measurement Design Centre, with the idea to replace communication…
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…
If you don't mind, can you carry out this project yourself?
You only need to download the next two things. :

Hello,
I'm not very familiar with half precision floating points, but I found an older TI document talking about them. Here it is for your reference.

In general, I would not recommend using…
Hello Imran,
Sure, we have the MSP432 line of devices which are Cortex M4F 32 bit controllers. You can find the parametric search for these devices below. These devices do not offer a 20 bit ADC though.

Hello Neeraj,
As explained by Mike in this e2e post , the MSPMATHLIB and MSP-IQMATHLIB are two different libraries. The MSP-IQMATHLIB can be downloaded from the library's web-page and is compatible with all of the MSP430 flash and FRAM devices. It's purpose…
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…
