器件型号:DRV8353

您好!

上电8353S 后、当 INLx 和 INHx 都为低电平时、GHx 和 SHx 为高电平。

请帮助检查它。

 以下是初始化代码:

bool DRV8353S_init (uint16_t dat)

{

uint16_t uRead0、uRead1、uRead5;

uint16_t Reg05 = 0x05AF;

uint8_t i;

Bool BRT = true;

for (I=0;I<RETRYTIMES;I++)

{

DRV8353S_Write (0x02、0x0001);

__ NOP();

__ NOP();

DRV8353S_Write (0x05、Reg05);

__ NOP();

uRead5 = DRV8353S_READ (0x05);

uRead0 = DRV8353S_READ (0x00);

uRead1 = DRV8353S_READ (0x01);

if ((Reg05==(uRead5&0x07FF))

&&(0x00=uRead0)&&(0x00==uRead1))

中断;

如果(I>=RETRYTIMES)

{

assert_failed ((uint8_t *)__file__、__line__);

BRT = false;

 

DRV8353S_Write (0x02、0x0060);

DRV8353S_Write (0x03、0x03FF);

DRV8353S_Write (0x04、0x07FF);

//DRV8353S_Write (0x05、Reg05);

DRV8353S_Write (0x06、0x0283);

DRV8353S_Write (0x07、0x0000);

返回 BRT;
