i think the big and little indian format is not the issue because
i'm setting the int32 value in the code it self for the testing for that also im getting the same
the hex value for the modbus data is 0x 43 5d 85 73
the data received in modbus is bytes of data only we have to type cast the the four byte of data to float 32
im communicating with the l&t multifun meter WL4400 for the parameter like voltage current pf energy for the display purpose
hi guys
im using ccs c complier PCH 16 bit
im reading the float data from modbus rtu as the array of byte and i convert the bytes to int32
while im type casting the int32 to float the result is 0.00
float ModbusGetdata(int8 in_ValueReg)
{
int8 Readcount = 0;
int8 ReadBuffer[15] = {0}...
U have to find the rms value of the signal
increase the sampling to 250 to 300 time for 100ms sampler one reading
multiply the obtained result and square root the mean value to get rms value
i guys i refered mazdi book of embedded system .. i need the asm coding for the floating operation...........
in c it working fine . but problem is it occupies more memory size while using sprintf fun......
