In this section we will see how to use 8085 to write a program in 8085 kit. We will also see how to debug the program and check the result after successful execution. Let us see a typical keypad structure of 8085 kit. (This keyboard pattern may vary indifferent kits of different manufacturers)The following table will show the functionalities of different control keys. There are 16alphanumeric keys (0-9, A-F) to provide data and address −KeysFunctionalitiesRESETReset the systemVCT INTVector Interrupt.

The ftp_nb_put() function uploads a file to the FTP server.Syntaxftp_nb_put(con,remote_file,local_file,transfer_mode,beg_pos);Parameterscon − The FTP connectionremote_file − The file to upload tolocal_file − The local file path to uploadtransfer_mode − This is the transfer mode. The following are the possible values:- FTP_ASCII, or- FTP_BINARYbeg_pos − The position to begin the downloadingReturnThe ftp_nb_put() function returns any of the following values −FTP_FAILED − send/receive failedFTP_FINISHED − send/receive completedFTP_MOREDATA − send/receive in progressExampleThe following is an example −
The method pathCompinent() is used to remove the file information from a filename and return only its path component. This method requires a single parameter i.e. the file name and it returns the path component only of the file name.A program that demonstrates this is given as follows −Example Live Demoimport java.io.File; public class Demo { public static String pathComponent(String fname) { int pos = fname.lastIndexOf(File.separator); if (pos > -1) return fname.substring(0, pos); else return fname; } public static void main(String[] ...

Firstly, create a Formatter and a Calendar object.Formatter f = new Formatter(); Calendar c = Calendar.getInstance();To display hour using Formatter class, use the ‘l’ conversion a character −f = new Formatter(); System.out.println(f.format("Hour: %tl", c));To display minute using Formatter class, use the ‘M’ conversion character −f = new Formatter(); System.out.println(f.format("Minute: %1$tM", c));The following is an example −Example Live Demoimport java.util.Calendar; import java.util.Formatter; public class Demo { public static void main(String args[]) { Formatter f = new Formatter(); Calendar c = Calendar.getInstance(); ...

In this program we will see how to divide a 16-bit number by an 8-bit numberProblem StatementWrite 8085 Assembly language program to divide a 16-bit number by an 8-bit number.DiscussionIn this program we are taking the 16-bit number from 8000H and 8001H. The 8000H is holding the lower order byte and 8001H is holding higher order byte. The8002H is holding the 8-bit numerator. After dividing the number the16-bit quotient is stored at location 8050H and 8051H. The remainderis stored at 8052H.InputAddressData......80002B8001CA800253......Flow DiagramProgramAddressHEX CodesLabelsMnemonicsCommentsF00021, 00, 80LXI H, 8000HPoint 8000HaddressF0037EMOV A, MStore the lower order byteF00423INX H Increase the HL pair to ...

An element can be removed from a stack using the java.util.Stack.pop() method. This method requires no parameters and it removes the element at the top of the stack. It returns the element that was removed.A program that demonstrates this is given as follows −Example Live Demoimport java.util.Stack; public class Demo { public static void main (String args[]) { Stack stack = new Stack(); stack.push("Apple"); stack.push("Mango"); stack.push("Guava"); stack.push("Pear"); ...

The microcomputer system basically consists of three blocksThe microprocessorThe memories of microprocessor like EPROM and RAM andThe I/O ports by which they are connected.The possible data transfers are indicated below.Between the memory and microprocessor data transfer occurs by using the LDA and STA instructions.Between microprocessor and I/O ports also data transfer occurs by the help of two instructions IN and OUT.Through DMA data transfer, data is transferred between the Input Output ports and the memory.If the data transfer which is used for reading from the memory location is 3456H and then writing to output port number is 50H which takes ...
