MPPT code in picbasic

[showtime]

Hello my friends,
I have just found a code about MPPT. I couldn't translate in Picbasic. I suppose an error in adjusting pwm duty. If you can translate the code i will be very happy. Thank you for now.
Best regards.

#include <16f876.h>
#DEVICE *=16 ICD=TRUE
#use Delay(Clock=20000000)
#use RS232(Baud=9600,Xmit=PIN_C6,Rcv=PIN_C7,brgh1ok)

float average_ad(byte chan) {

int i,avg_num = 32;
float avg = 0, temp_avg = 0;

set_adc_channel(chan);
delay_us(100);
for (i=1; i<=avg_num; ++i) {
avg += read_adc();
delay_us(100);
}
return(avg/avg_num);
}

void pwm1_duty100(long pwm_percent, long pwm_maximum) {

set_pwm1_duty((pwm_maximum/100)*pwm_percent);
}

main()
{
CONST float CHARGED = 14.4;
CONST long NDELTA = -1;
CONST byte AMP_CHAN = 0, BAMP_CHAN = 3, BVOLT_CHAN = 2, VOLT_CHAN = 1;
float current, voltage, watts = 0.0, old_watts = 0.0;
float batamps, batvolts, batwatts;
float temp_watts, watts100, amp100, volt100;
long delta = 1, pwm_max, pwm100;
long boost = 0, boost_counter;
byte led_count = 0;

output_low(PIN_C3);
setup_port_a(ALL_ANALOG);
setup_adc(adc_clock_div_32);
setup_timer_2(T2_DIV_BY_1, 49, 1);
setup_ccp1(CCP_PWM);
pwm_max = 200;
pwm100 = 85;
pwm1_duty100(pwm100, pwm_max);
output_high(PIN_C3);
output_high(PIN_C0);
delay_ms(1000);

while(TRUE) {
if (batvolts > CHARGED) {
delta = NDELTA;
output_high(PIN_C5);
}
else if (old_watts > watts) {
delta = -delta;
output_low(PIN_C5);
}
old_watts = watts;
pwm100 += delta;
if (pwm100 > 100) pwm100 = 100;
else if (pwm100 < 0) pwm100 = 0;
pwm1_duty100(pwm100, pwm_max);

current = average_ad(AMP_CHAN)/40.885;
voltage = average_ad(VOLT_CHAN)/18.2887;
batamps = average_ad(BAMP_CHAN)/41.3428;
batvolts = average_ad(BVOLT_CHAN)/20.4831;

watts = current * voltage;
batwatts = batamps * batvolts;

output_bit(PIN_C0, (++led_count & 0x01));
delay_ms(500);

}
}

Nobody have to help in this point. Also I don't know if it is a problem wishing a code translation. But please help me. I would like just to know if there is an error in this code.

There's a really few amount of member here who deal with C... hence why there's no real answer to your previous post. There's also few C variant... CCS, Hi-tech, MikroC etc etc etc

This would help if you tell us what you need to do and if you really understand the MPPT basics...

Of course my target is MPPT project. But I didn't understand anything. I have got some idea about MPPT in theory but not in code level.
