UART Transmitting HEX Data
Up until now, the external UART only transmitted text - whatever the user typed in the Tx field was transmitted to the 8051. Now, a set of 8-bit numbers (written in HEX) can be transmitted. To do so, the user encloses the set in curly braces, each number separated by a comma, as shown in the image opposite. When text is transmitted, it is terminated by 0DH. This is not the case with a set of numbers. In the example shown opposite, the four numbers 56, 3a, 23 and e7 are transmitted, nothing more. If the user wishes to send {56, 3a, 23, e7} as text rather than a set of 8-bit numbers, the text is escaped using the \ character. Therefore, \{56, 3a, 23, e7}in the Tx field would result in {56, 3a, 23, e7} followed by 0DH being transmitted to the 8051.
LCD Module
A simulation of the popular Hitachi HD44780 LCD module has been implemented for the EdSim51 Simulator. The user can toggle between the LED display and the LCD display by clicking on the blue button above the display. And now CGRAM has also been implemented. Find out more.
Zoom
For high resolution monitors, click on the zoom button. The zoom button is located below the red Exit button.
