Part Number: TMS320F280049
Other Parts Discussed in Thread: C2000WARE,
Hi
I give here the steps to adapt the example C:\ti\c2000\C2000Ware_1_00_06_00\device_support\f2807x\examples\cpu1\buffdac_sine_dma\cpu01 to the TMS320F280049.
1) Fix a SW bug in the ConfigCpuTimer from driverlib and device support
Timer->RegsAddr->PRD.all = temp-1;
2) Fix an other bug on Sin table computation
SINE_TBL[j] = (sin(j*2.0*PI/(double)SINE_TBL_SIZE)+1.0)*2047.5;
Indeed the code gives SINE_TBL[j] = (sin(j*PI/180.0)+1.0)*2047.5; which is only valid for a SINE_TBL_SIZE equals to 360.
3) Comment this code line
//CpuSysRegs.SECMSEL.bit.PF1SEL = 1;
