Why are taxiway and runway centerline lights off center? Normally the terminal window is shown by default when you simulate the circuit but if you don't see it you can click on Virtual Terminal in the Debug menu. Thanks for contributing an answer to Electrical Engineering Stack Exchange! Can someone tell me where I am wrong. "fuses" are simply special flash locations that use individual bits to control various settings of the micro, such as the source of its system clock (internal or external) 7 for the internal clock source its frequency. Save the new configurations and rebuild the project. How could a mega128 ever run at 16MHz without some kind of external clock circuitry. Use this frequency as per your code. So, let's get. I used STM32F103C6, Proteus 8.11, STM32CubeMX and HAL Library to initiate the project. To learn more, see our tips on writing great answers. The crystal uses 8MHz .

Instead of RFID reader i am using Virtual Terminal for sending or scanning RFID, here in my case I am Typing ID in . even for that case the virtual terminal in proteus stops taking chars after a certain length. It's important to understand that there was never any problem with the virtual terminal; the virtual terminal was never not working! I cannot explain this. JavaScript is disabled. Am using Atmel Studio7 as the IDE and proteus for simulation. I think the problem is with clocking the MCU and once i manage to do that all will run as expected. Please take note of the following; Having the code doesn't necessarily mean that it'll work - You need to configure your project and Proteus simulation accordingly; Below am going to walk you through the necessary configurations To add the files to your project, go to the menu View Solution Explorer right clicking on the project and choosing Add -> Existing Item then select the files, NOTE that the micro-controller CSKEL Fuses have to be set to [1111] and also specify the frequency under clock frequency as 16000000 as shown in the photo above, Follow the same procedures as the terminal (Double click the terminal component and set its baud rate to 19200) refer to the photo below.

For those who have similar issues or would like to try it out just follow the link I provided and download the source code, then include the files UART_routines.c and UART_routines.h in your project (am using Atmel Studio 7.0). Going from engineer to entrepreneur takes more than just good code (Ep. The datasheet just tells you the permissible clock rates - it knows nothing about the actual clock in your particular circuit! That's good. Again, the virtual terminal was showing normal output all the time - for the data it was receiving. I also thought that the problem was baud rate but I can't seem to get the correct baud rate, I keep changing the f_cpu none of them seems to output the correct data. Now make the connection between two virtual terminals boxes as shown here. Now in the search box type " COMPIM " , when you search this a result will show up as shown in the below figure: After Selecting this, click OK to add this component in the database.
