Hi This question has probably been asked many times but because the site search engine returns 0 results : compiling sprintf(...,"...."...); linker returns : undefined reference to __io_putchar I have checked and small printf no-floats is selected, UART0 - No Thanks in advance |
Thanks - sorted out UART0 must = YES
problem it adds over 4K code and 280bytes data - double my project size.
have to find a simple printf version.
