Bus Connections in PROTEUS Simulation

Bus Connections in PROTEUS Simulation

When using PROTEUS for simulation, the pins of each component can be connected directly with wires, labeled connections, or using a “bus”. In the PROTEUS component library, some components have pins that are connected in a “bus” format, such as the 8031, 8155, 8255, etc. Therefore, for these components, the connections must be made using … Read more

Getting Started with Proteus: AVR Microcontroller Simulation Example

Getting Started with Proteus: AVR Microcontroller Simulation Example

Before starting, prepare the simulation file, which is the debugging or download file generated by the compiler. Different compilers produce files in different formats, such as ICC produces COF, IAR produces D90, and GCC produces COF and ELF. Proteus 6.7sp3 supports COF, D90, HEX, etc., but does not currently support ELF. This example uses: lcd_C.hex … Read more
