Demonstrates the floating number the script (AVR ) AVR, floating-point _AVR,float
Friday, November 20th, 2009 at 17:44 | No commentsCategories: Embedded systemShort Content: If the write program processes the floating number, that is the matter which has a headache very much. Fortunately, each kind of C language develops the platform to have the ready-made floating number processing function, moreover CodeVisionAVR also provided the floating number to transform the string of character form the function, let look like me such “the small colza” to be crisp: )! This article is a demonstration floating number script which writes with CodeVisionAVR, but also involved ... -

In AVR-GCC defines API_GCC, AVR, API
Friday, November 13th, 2009 at 16:22 | No commentsCategories: Embedded systemShort Content: The embedded programming's code may divide into two parts simply; first, has nothing to do with the algorithm part with the hardware, has not distinguished to its programming and the ordinary C programming; Second, with hardware related register/port operation part. Different MCU realizes the method to have the difference respectively. Solves in AVR-GCC through a series of API. Certainly, the user may also define own API. In this introduces API which simply in present AVR-GCC defines, as well ... -
