Re: [avr-gcc-list] sprintf problem
Hello all,The problem I posted here has been rectified by using a dummy malloc, allocating about 10 bytes. This is for information only.

I have also checked the Stack Pointer by sending its content to serial port. It appears to be OK (not unduly decreasing/increasing). Any suggestions to locate the bug please???

Re: [avr-gcc-list] sprintf problem
Hello all,The problem resurfaced after little more code is added to my program. Optimisation is set to s. Sprintf behaves funny with %f. I am giving below sample code and the outputunsigned char buffer[100];sprintf (buffer,"Hello %f hello\n\r", 34.56);send_2_serial (buffer);the output for the first two times is correctHello 34.56 helloBefore every output some other reasonably large calculations are carried Hello 34.56 helloHello hello The float converted string is missing.Could anybody throw some light on why this is happening?

[avr-gcc-list] sprintf problem
Hello all, In one of my projects (ATMega128 based) I am using floating point numbers and sprintf to write a formatted record to a buffer. Tthe buffer contents is then sent to a mini printer. The first two records print properly and thereafter I am getting garbage from sprintf!! The optimisation was set to 0. When I change the optimisation to s, then correct data is being printed!! Moreover there is a difference in the way _delay_loop_2 and _delay_loop_1 delays are generated with different optimisations. I would like to know the reason why this is happening (specially with sprintf) to avoid any pitfalls in my coding. Thanks in advance.Nayani P Yahoo!
