![]() Opening Atmel Studio 7 Project SettingsĬlick Toolchain in the page at the left of the project properties page and then General under the AVR/GNU Linker item as shown in the image below. The image below shows the menu in Atmel Studio 7 for a project named print_float_mega_2560. to bring up the properties page for the currently open project. In Atmel Studio 7 on the top menu, click Project → Properties. Sprintf(out_str, "flt_num = %f\r\n", flt_num) Ĭhanging Linker Settings to Print Floating Point Numbers in Atmel Studio 7 The test code used is shown in the following listing.Ĭhar out_str = // string to print to and transmitįloat flt_num = 31.8394 // float number to print to string Where 1) above is before changing linker settings to enable printing of floating point numbers (output printed to string is: flt_num = ?) and 2) is after changing the linker options as described below (output printed to string is: flt_num = 31.8394). AVR Memory UsageĪfter building a simple C program in Atmel Studio 7 that uses sprintf() to print a floating point number to a string and send it out of the serial port (USART0) of an ATmega2560 microcontroller, the following memory usage was recorded. ![]() The solution to this problem is to change some linker settings so that the floating point number is printed as expected. Computer that has a 1.The reason that floating point numbers are not printed is because the default settings in Atmel Studio disable them for sprintf / printf type functions to save microcontroller memory.Windows Server 2012 and Windows Server 2012 R2.Windows Server 2008 R2 Service Pack 1 or higher.How to install Official and Professional IDE for Arduino/ATmega328p?.How to install Old Version of Atmel Studio?.How to install Atmel Studio in Windows 10?.I still recommend the old Atmel Studio 7.0 released by Atmel as it stable and works great out of the box.
