CCS/CC2640R2F: Display_print using %f or float format does not work?

Hi,

When I try to print at uart console a float number example 1.02432 using Display_print() %f. The output is f only. What works is if I use sprintf to store the re-format float value in a char array, then use Display_print.

It has been ages with no news from you, friend.

Did you check this:

Hi Tom,

The level of printf/scanf is already set to full. Seems there is no workaround but to use sprintf first.

I am just around and mostly active at TI BLE Forum due to my work.

From a search I think Display_printf internally uses the XDC tools System_vsnprintf() function. By default XDC tools doesn't support the full range of format strings specified by the C Standard.

To get decimal floating point support try adding "%f" to the System.extendedFormats configuration string.
