The default setting is to have the ports for all the target systems to be inputs (Data Direction bits to be all I s) in their Tri-state mode. 3Ĥ Configuring the Input/Output Ports Select the Ports tab to determine how the I/O ports are to be initialized for the target system. The following window will be displayed: 2ģ The above window opens and, for this example project, we shall select the AT90S8515 microcontroller and set the clock rate to 3.68 MHz since that is the clock on the STK500 starter kit. Creating a New Project In order to create a new project, select the File New menu option or press the toolbar button.
Enter C:\Program Files\Atmel\AVR Studio\AvrStudio.exe and press the OK button.
Codevision avr software generator#
Using the CodeWizardAVR Automatic Program Generator The CodeWizardAVR simplifies the task of writing start-up code for different AVR microcontrollers.
The following dialog window will open: Press Yes to use the CodeWizardAVR Automatic Program Generator. Select the Settings Debugger menu option. In order to be able to invoke the AVR Studio debugger/simulator from within the CodeVisionAVR IDE one final setting must be done. Then press once again the OK button in order to save the Programmer Settings. Then the following window will be displayed Select the c:\program Files\Atmel\AVR Studio\STK500 directory and press the OK button. The following dialog window will open: 1Ģ Select Project and press OK. Then press the STK500.EXE Directory button in order to specify the location of the stk500.exe command line utility supplied with AVR Studio. Make sure to select the Atmel STK500 AVR Chip Programmer Type and the corresponding Communication Port which is used with the STK500 starter kit. Connect one 6 pin ribbon cable between the ISP6PIN and SPROG3 headers. This will allow displaying the state of AT90S8515 s PORTB outputs. Connect one 10 pin ribbon cable between the PORTB and LEDS headers. Also set the OSCSEL jumper between pins 1 and 2. Make sure the power is off and insert the AT90S8515 chip into the appropriate socket marked SCKT3000D3. Setup the starter kit according to the instructions in the STK500 User Guide. The demonstration program to be developed in the next few pages requires an Atmel AT90S8515 microcontroller and the STK500 starter kit. It is assumed that AVR Studio was installed in the default directory: C:\Program Files\Atmel\AVR Studio.
Codevision avr software install#
Install the Atmel AVR Studio debugger by executing the file setup.exe. It is assumed that the program was installed in the default directory: C:\cvavr. Preparation Install the CodeVisionAVR C Compiler by executing the file setup.exe. The example, which is the subject of this application note, is a simple program for the Atmel AT90S8515 microcontroller on the STK500 starter kit. The following dialog window will open: Introduction The purpose of this document is to guide the user through the preparation of an example C program using the CodeVisionAVR C compiler. In order to use this feature, one supplementary setting must be done: Open the CodeVisionAVR IDE and select the Settings Programmer menu option. This will allow CodeVisionAVR to automatically program the AVR chip after a successful compilation. Creating a New Project using the CodeWizardAVR Automatic Program Generator Editing and Compiling the C code Loading the executable code into the target microcontroller on the STK500 starter kit. 1 Getting Started with the CodeVisionAVR C Compiler Features Installing and Configuring CodeVisionAVR to work with the Atmel STK500 starter kit and AVR Studio debugger.
