Practical DSP28335 Programming Ideas [Copy link]

When developing DSP, you need to configure its underlying hardware and peripherals accordingly. Only after the configuration is completed can you activate its corresponding modules and then write and debug programs inside it. The following is a simple summary of program configuration and operation for reference only.

Step 1: Initialize system control, PLL, watchdog, enable peripheral clocks, etc., generally call the function InitSysCtrl();

Step 2: Initialize GPIO, and perform different function configurations for different hardware systems;

Step 3: Clear all interrupts and initialize PIEinterrupt vector table

DisableCPUinterrupts

DINT;

InitializePIEcontrol registers to default state

InitPieVectTable();

DisableCPUinterrupts and clear allCPUinterrupt flags

IER=0x0000;

IFR=0x0000;

InitializationPIEInterrupt vector table

[align=left ] InitPieVectTable();

EALLOW;

XXX-------Fill in the interrupts needed in the program here and map them to the interrupt vector table(Such as

Pie VectTable.SCIRXINTA=&sciaRxFifoIsr;)

EDIS;

Step 4: Initialize all peripherals(If there is no peripheral structure, this part can be omitted)；

Step 5: User program segment, enable interrupts.
