I want to use resolver interface using eTPU in MPC5676R.
I want to generate a square wave using the fs_rslv_init function according to AN3943 documentation.
I initialized it as shown in the document, but no square wave is generated. The code is written as below. I would like to know if there are any additional settings to make square waves here.
SIU.PCR[126].R = 0x0603;
err_code = fs_etpu_rslv_init (12,/* engine: A; channel: 12 */
FS_ETPU_PRIORITY_LOW,/* priority: Low */
FS_ETPU_RSLV_MODE_MASTER ,/* mode: FS_ETPU_RSLV_MODE_MASTER*/
10000,/* period: 10000 */
5000,/* duty: 5000 */
7500,/* delay: 2500 */
-3056,/* start_offset: -3056 */
0, //Sample delay
10,/* scale: 10 */
10,/* scale: 10 */
0x002B851E, /* dc_offset */
0x002B851E, /* dc_offset */
0,/* link_chan: 0 */
0,/* rate_irq: 0 */
0,/* rate_link: 0 */
0x005E87CE,/* k1_d: 0x004056fe */
8,/* k1_scale: 8 */
0x00433A20,/* k2_d: 0x00517cc2 */
8);/* k2_scale: 3 */
if (err_code != 0)
{
return (err_code);
}
