HI,
i am new in embedded coding and from the past couple of weeks i am working on a code to interface external interface zone 7 of TMS320F28335 with an external device using XD0-XD7 (8 bits). though i am not sure if i am writing the correct code.
First of all i have defined an address location MAX2982 in zone 7 using the following code.
#define MAX2982 (Uint16 volatile *)0x200000 //Zone 7 address
now , under a specific interrupt service routine i am writing to the external interface zone 7 using the following commands.
for (ndx = 0; ndx<50 ; ndx++)
{ *MAX2982 = (TestBuf1[ndx]); // TestBuf is defined as a 16 bit unsigned integer. and contains some test values
}
Next for reading the external interface zone i am using
for(ndx2=0; ndx2<50; ndx2++)
{
MAX2982_data = *MAX2982;
TestBuf2[ndx2]= MAX2982_data;
}
Kindly reply if i am doing it right or wrong.
