Is float point permited in interrups ? Were I can find recomendations on float point in interrupts for RV compiler and lpc21xx target ?
There are no limitiations in using Floating arithmetic in interrupts.
But what about
__irq Enables a C or C++ function to be used as an interrupt routine called by the IRQ or FIQ vectors. All corrupted registers except floating-point registers are preserved, not only those that are normally preserved under the AAPCS. The default AAPCS mode must be used.
Wow, now I know, I know: There are no limitiations in using Floating arithmetic in interrupts. ...Exept default stack configuration for Interrupt mode 0x0000 0080
Happy New Year and Merry Christmas to you!
