From: bhaskar on 5 May 2010 13:25 Hi to all, I am the begginer in microblaze. I want to just print the value of the float variable "fpu" (=2.345) on the uart. can you please tell me how to write it in the microblaze (C), Can you tell me right from the include statements, because I not even know what are the header files it usesw to include floating point unit. I have just added FPU in the BSB launcher when the EDK invokes. I dont know what should i do later. Plz help me Thanks Bhaskar --------------------------------------- Posted through http://www.FPGARelated.com

Plz help me Have you tried - does something like this not work? #include <stdio.h> int main(void) { float somefloat=2.345f; printf("%f\n", somefloat); } XPS should sort everything out behind the scenes for this to work.You do have to use "proper" printf() rather than xil_printf() which means your elf file gets pretty big all of a sudden though. Don't try and run it out of internal memory! Cheers, Martin -- martin.j.thompson(a)trw.com TRW Conekt - Consultancy in Engineering, Knowledge and Technology http://www.conekt.net/electronics.html |
