EDSIM51 USER GUIDE PDF

The user can set the number of instructions executed between updates to the simulator GUI by selecting a value from the Update Freq. menu. Certain update. Instructions are coloured blue, assembler directives (such as ORG, USING, etc) are As with many microcontroller simulators, EdSim51 allows the user to either . User Manual.

Edsim51 Examples

By default the keypad mode is set to Standard. The 4 X 3 keypad is interfaced in a standard format, as can be seen in the logic diagram extract above.

The first bytes of code memory are displayed. In other words, the next instruction to be executed will be the breakpoint instruction. This allowed the programmer to observe changes in the hardware and registers for each executed instruction.

EdSim51 – User’s Guide

When the motor’s shaft lines up with the sensor, the sensor changes from black to red, as shown in the image on the right. F5H must be written as 0F5H. Also, if you let the mouse tuide hover over one of the bits momentarily, the bit’s description is displayed, as shown below:.

The user can select from a list of standard Baud rates, as shown above. By default, data memory is displayed. For more information on the serial port and on adding a parity bit, click Beginner’s Guide to the – Serial Port. Acceptable values are in the range 0. Notice the sensor depicted by a vertical line at the top of the motor is black. Clicking on the button at this point clears the Tx window. But it can be expanded. The example on page 42 is for a 1-line display, but it nonetheless explains clearly how to initialise and communicate with the module in 4-bit mode.

The keys can also be set to simulate switch bouncing – more info.

The PSW is bit-addressable, therefore the background of each bit is white and the user can change any of the bits directly. The keypad can be implemented using the external interrupt 1 line see keypadbut not while also multiplexing the 7-segment displays. Up until now, the external UART only transmitted text – whatever the user typed in the Tx field was transmitted to the The selection of which of the four displays is enabled guid done via P3.

As can be seen in the logic diagram extract above, ugide lines are also connected to the external UART. Binary values are entered by appending B usdr the number as shown in the image below. So the user knows a switch is bouncing, its colour alternates between red switch open and dark red switch closed.

In the example shown opposite, the four numbers 56, 3a, 23 and e7 are transmitted, nothing more. Those that are grey cannot. If H is used, the number cannot begin with a letter example: The analogue output for this data will be displayed on the scope until the next time WR is taken high and a new value is placed in the internal register. A simple assembly program is shown in the assembly code panel to the left.

Now the user can choose from a list of Baud fdsim51. When the background of the assembly code text area is white is guiide editable.

For the entered number to take effect, the user must hit Enter on the computer keyboard. The analogue input that is applied to the ADC is also applied to the non-inverting pin of the comparator, as can be seen above in this extract, since the ADC is disabled, the analogue voltage connection to the ADC is omitted.

Fuide label can only be one character in length. The truth table for the bridge and its effect on the motor is:. Either way, the program will first be assembled. However, it should be noted that this will result in the machine code and the assembly program being different. However, the programmer is still expected to write the code that sets the module in this mode. This is because the TMOD register is not bit-addressable – the user cannot alter these bits directly.

Therefore, the user can now enter a number use than select a value from the list.

The programmer can write code directly here, or can load a program from file using the Load button dealt with in the next section. The simulator was designed so that everything is visible on the screen at the same time suer the internal registers, the source code, the peripherals, etc.

These images shows what is connected to each of the 32 port pins. If the mode is not ecsim51 correctly, an error message stating such is displayed, as shown here.

You can select code in the assembly text area and copy it to the system clipboard using the Copy evsim51, the same as you do in your word processing package. Radio – in radio mode only one key at a time can be closed.
