Communication

Utilising 2 mirko bus at the same time on easy v7 development board.

I would like to have a code that can run 2 hall current clicks at the same time on the same board and be able to display it on the 2x16 LCD. Below is the code I have written but have been stuck since. Please correct or guide me into the right coding.

//Lcd module connections
sbit LCD_RS at LATB4_bit;
sbit LCD_EN at LATB5_bit;
sbit LCD_D4 at LATB0_bit;
sbit LCD_D5 at LATB1_bit;
sbit LCD_D6 at LATB2_bit;
sbit LCD_D7 at LATB3_bit;

sbit LCD_RS_Direction at TRISB4_bit;
sbit LCD_EN_Direction at TRISB5_bit;
sbit LCD_D4_Direction at TRISB0_bit;
sbit LCD_D5_Direction at TRISB1_bit;
sbit LCD_D6_Direction at TRISB2_bit;
sbit LCD_D7_Direction at TRISB3_bit;
// End LCD module connections

sbit Chip_Select at RE0_bit;
sbit Chip_Select_Direction at TRISE0_bit;
sbit Chip_Select1 at RA5_bit;
sbit Chip_Select1_Direction at TRISA5_bit;

char txt[15], txt1[15];
int current_read, current_read1, i, value;
float current_read_float, current_read1_float;

// Get current value from 1
unsigned Hall_Read() {
// Local variable
unsigned int tmp = 0, tmp0 = 0, tmp1 = 0;
unsigned int buffer = 0;

Chip_Select = 0; // Select MCP3201
tmp0 = SPI1_Read(buffer); // Get value
tmp1 = SPI1_Read(buffer); // Get value
Chip_Select = 1; // Deselect MCP3201

tmp = ((tmp1) | (tmp0 << 8));

return tmp; // Returns value
}

// Get current value
unsigned Hall_Read1() {
// Local variable
unsigned int tmpA = 0, tmp0A = 0, tmp1A = 0;
unsigned int buffer = 0;

Chip_Select1 = 0; // Select MCP3201
tmp0A = SPI1_Read(buffer); // Get value
tmp1A = SPI1_Read(buffer); // Get value

while(1) {
// Read current from Hall Click
current_read = Hall_Read();


// If Sensor Current Value Transmission
if ((current_read >> 15) == 0) {
current_read = current_read & 0x1FFF; // Get [13:0] bits of current value
current_read = current_read - 4096; // Map the current value
current_read_float = (float)current_read * 0.0125; // Calculate the current value in Amperes

sprintf(txt, "%2.1f", current_read_float); // Trim the string from leading spaces
