: Ensure your project clock frequency matches hardware. Go to Project → Configure → C Compiler → Clock . Set to actual crystal/RC frequency. Default is 4 MHz, which is often wrong for custom boards.
The software supports an extensive range of hardware interfaces, including: Atmel AVR ISP MkII AVRISP and STK500 boards JTAGICE (MkI and MkII) Various parallel and serial port low-cost DIY programmers Chip Configuration and Fuse Bits CodeVision AVR 2.05.0 Professional
CodeWizardAVR provides a graphical user interface where you can simply click checkboxes and select dropdown menus to configure your hardware. With a single click, it generates fully commented, ready-to-compile initialization code. 3. Extensive Built-in Libraries : Ensure your project clock frequency matches hardware
You don’t need external software to flash your compiled hex file onto the target microcontroller. CodeVisionAVR features a built-in ISP programmer that supports a wide array of hardware tools, including the Altera ByteBlaster, AVR Dragon, STK500, and various custom USB ISP programmers. Why Version 2.05.0? Default is 4 MHz, which is often wrong for custom boards
The following example demonstrates the clean, readable code generated by CodeVisionAVR 2.05.0 Professional to toggle an LED on Port B every time Timer 0 overflows.
