I´m trying to use floating point on FreeRtos / LPC2368 / newlib environment !
Yes I know, float and small uC w/o hw-math is not the best, but is good enough to quickly start some tests.
I’m able to run math functions like sin, cos, …, but the system fails on sprintf( " … %f ").
I dig the network and I get confused about newlib and reentrancy!
At this time I don’t need functions like write_r …, to interface printf to UART, I’d like to get a formatted string.
Is anyone using sprintf with float data?
my gcc env:
