Could u please sent the library And model files for max 232 for proteus. İ have one but its sayin for all the pins of max232 not modeled when i rün a simulatiion
Read Coil Status (FC=01)

This command is requesting the ON/OFF status of discrete coils # 20 to 56
from the slave device with address 17.

confused!!!! :((

just tell me which values should be in buffer[1] and buffer[6] if my counter is 15 to do execute return?
if ((buffer[1] == 16)&(((unsigned int) buffer[6] + 9)!=counter)) return 2 ;
buffer[1]=0x10 and buffer[6] different than 0x06 ?
this means that (buffer[1]==16) if it gives zero and (((unsigned int) buffer[6] + 9)!=counter) if this also gives zero
then if do & i will get zero but if i do && i will get 1 ?
if ((buffer[1] == 16)&(((unsigned int) buffer[6] + 9)!=counter)) is it the same thing
if ((buffer[1] == 16)&&(((unsigned int) buffer[6] + 9)!=counter))
if not which one is correct? if both of them correct what is the difference?
if ((buffer[1] == 16)&(((unsigned int) buffer[6] + 9)!=counter))
(buffer[1]==16) gives one bit result 1 or 0
(((unsigned int) buffer[6] + 9)!=counter) gives one bit result 1 or 0
then and (&) these two values and see if it is 1 or zero ? is this correct ...
unsigned int modbuscrc(unsigned char *buf,int len)
{
unsigned int crc = 0xffff;
int pos;
for (pos = 0; pos < len; pos++)
{
crc ^= (unsigned int)buf[pos]; // XOR byte into least sig. byte of crc
for (int i = 8; i>0; i--) { // Loop over each bit...
In my opinion the important think is matching the battery voltages times charge currents must be bigger than your solar panel can produce. if so you have achieved mppt.
for example you have 12 volt battery and its capacity is lets say 20Ah. so you have to charge it with 14 volt and max 2 A...
after plus 1 it is showing minus, like -1.115 :) nbut i have make some corrections. i think you overlooked the errors.
LongToStr((int)(-Value), String); this line corrected like this. sLongToStr((int)(Value), String);
and ty again. you are so helpfull.
