ATSAMC21 I/O 初始值是HI OR LO OR 高阻抗, 要找哪份文件有說明

hi Libra
感謝~~~~
左邊是0.001ms時, Gen出來的設定, 右邊是1ms時, Gen出來的設定,

我去看 Harmony 3 只能配置最小單位: ms ,如何可以產生us

感謝,我是用 atsmac21j18a

請教各位: 如何在Harmony 3 設定SPI MODE3: CPOL=1 CPHA=1

#define wr_addr_ 0x20 //指定寫入位址
#define datalen 100 //

HI Libra
感謝,再次請教我如果要指定位址寫入,下列方法可行?
SERCOM2_I2C_Write(slaveaddr,wr_addr_ ,datalen);




Write之後等一下tWR (5ms max)試試,
另外SERCOM2_I2C Read/Write 第一個欄位一律為Slave Address, 然後對當前的地址讀/寫,

如果你要指定讀取位址時, 應該使用SERCOM2_I2C_WirteRead()
#define SLAVE_ADDR 0xA0
uint8_t SubAddr[1];
uint8_t ReadData[16];
SubAddr[0] = 你要讀的位址; // 0x00為重頭開始讀
SERCOM2_I2C_WirteRead( SALVE_ADDR, SubAddr, 1, ReadData,16 );[/quote]

uint8_t EERD_BUF[16];
uint8_t TEST_DATA[16];


void Get_ AT24MAC402_MAC(uint8_t *MAC_BUF)
{

uint8_t SubAddr[0];
SubAddr[0] = 0xA0;

SERCOM2_I2C_Write( 0xA0, SubAddr, 1);
while(SERCOM2_I2C_IsBusy());

SERCOM2_I2C_Read(0xA0,MAC_BUF,16);
while(SERCOM2_I2C_IsBusy());
__asm("nop"); //設定斷點程式有跑到這 查看EERD_BUF 都是0
}


int main ( void )
{
uint8_t i=0;
for (i=0 ;i < 16 ; i++)
{
TEST_DATA[i]=i; // 初始化填入測試數據入

}
SERCOM2_I2C_Write(0xA0,&TEST_DATA[0],16);
while(SERCOM2_I2C_IsBusy());
__asm("nop"); //設定斷點程式有跑到這

Get_AT24MAC402_MAC (&EERD_BUF[0]);

while ( true )
{
/* Maintain state machines of all polled MPLAB Harmony modules. */
SYS_Tasks ( );
__asm("nop");
return ( EXIT_FAILURE );
}

}

HI Ryang
感謝我在試試~~~~

真的很不錯,可以提供 ATSAMC21J18A 例程?

請教各位有人遇過? 使用 Harmony 工具產生程式碼,為何編譯會有問題

我使用 MPLAB X IDE: V4.15 ,XC32: V2.50
