this is my code I'm stuck in the adc part I'll explain what I do:
I have 7 analog channels to be converted:
AN0: need to be *4
AN1:
AN2:
AN3: need to be * 50
AN4: need to be * 50
AN5: need to be *4
AN6: need to be *4
but in the simulation all channels are correct except for 50 ?? here is my code

Code:
unsigned char lowbyte;

unsigned char medbyte;
unsigned int conversion1 ;
unsigned int TAB[24][7];
unsigned int conversion[12];
void main()
{
int i= 0;
/////////Initialization//////////////////

ADCON2=0xAD; //Right justified, 12TAD, 16TOSC
TRISA=0xFF; // set trisA as inputs
TRISE=0b1111; // set trisE as inputs
ADON_bit=1; // enable conversion
UART1_Init(9600); // Initialize hardware UART1 and establish communication at 9600 bps
Delay_ms(100); // Wait for UART module to stabilize

while(1)
{
for( i=0 ;i<7;i++)
{
conversion[12] = ADC_Read(i); // Read analog value from channel 0 to 6
