Introduction Block Diagram Functional Blocks Circuit Diagram Algorithm Flowchart Pros & Cons Future Expansion References 5 › { Algorithm for ADC } Step1: Start Step2: Load ADCON0 with 80H and ADCON1 with 81H for selecting RA0(89H for selecting RA1) as analog input port Step 3: Set A/D conversion status bit, ADGO =1 to start conversion. Step 4: Check if ADGO=0( i.e. A/D Conversion complete), if yes transfer higher 2 bits in ADRESH to a variable and shift it to left 8 times, then OR the contents with lower 8 bits in ADRESL. If no, go to step 4. Step 5: Compare the digital value with a threshold, and transmit it via UART. Step 6: Stop The same procedure is done for the data input at analog channel RA1.

Introduction Block Diagram Functional Blocks Circuit Diagram Algorithm Flowchart Pros & Cons Future Expansion References 5 › { Algorithm for asynchronous transmission } Step 1: Start Step 2: Configure PORT C as output port Step 3: Select asynchronous transmission by clearing SYNC bit. Step 4: Set the transmit enable bit (TXEN) to enable data transmission Step 5: Set BRG bit for high baud rate selection Step 6: Initialize SPBRG= 128 for the baud rate 115200 using the equation Baud rate= fosc/(16*(x+1)) Step 7: Enable serial port by setting Serial port enable bit, SPEN Step 8: Move the character to be sent to the transmit register, TXREG Step 9: Check if transmit shift register status bit, TRMT =1. If yes, transmission completed. If no, go to step 9 Step 10: Stop

Introduction Block Diagram Functional Blocks Circuit Diagram Algorithm Flowchart Pros & Cons Future Expansion References 5 › { Algorithm for Gloves } Step1:Do the basic Initialization –ADC,USART(115200 bps), PULL UP keys etc Step2:Take ADC readings through channel 0 and 1 continuously when PULL UP key(RB2) is pressed Step3: If channel0 (X - axis) value is less than current ADC value send 'L' to USART. If greater then send 'R' Step4:If channel1 (Y - axis) value is less than current ADC value, send 'D' to USART. If greater then send 'U' to USART Step5:If PULL UP key RB1 is pressed send '#' to USART(for right click command) Step6:If interrupt key RB0 is pressed once send '$' to USART(for single click command) And if RB0 is pressed twice send “$ $” to USART(for double click command) Step7:Goto step 2

Introduction Block Diagram Functional Blocks Circuit Diagram Algorithm Flowchart Pros & Cons Future Expansion References 5 › { Algorithm for Mouse Action } Step 1: Start Step 2: Declare library functions (from API Viewer and MSDN) for configuring mouse actions Step 3: Set the properties of MS Comm1 and MSComm2 Step 4: Create a form such that when the port is open display COM1-COM8 for COMM PORT selection Step 5: Get the current cursor position and compare the data in inbuff with L, R, U, D and set the cursor point to that direction by 2 pixels. If the data is $, # or * perform left click, right click or double click. Continue checking the data received at COMM port. Step 6: Stop
