TI中文支持网Dear Sir,
請問我在CC2640若要發射CW波測試頻點,我該使用哪一個function,
我爬了文章與程式碼似乎可以呼叫HCI_EXT_ModemTestTxCmd(1,1);
但我使用了Simple_peripheral專案檔中,
我在main.c的加入了這function,但從頻譜儀中,看不出來有CW波的出現,
以下是我的程式區段,不知是否有先進,可以提供一些指教.???
謝謝大家…
int main()
{
#if defined( USE_FPGA )
HWREG(PRCM_BASE + PRCM_O_PDCTL0) &= ~PRCM_PDCTL0_RFC_ON;
HWREG(PRCM_BASE + PRCM_O_PDCTL1) &= ~PRCM_PDCTL1_RFC_ON;
#endif // USE_FPGA
/* Register Application callback to trap asserts raised in the Stack */
RegisterAssertCback(AssertHandler);
PIN_init(BoardGpioInitTable);
HCI_EXT_EnablePTMCmd();
HCI_EXT_ModemTestTxCmd(1,1);<<<<<加入此function,實際跑過,並無CW.

Viki Shi：
HCI_EXT_ModemTestTxCmd实现的就是CMD_TX_TEST command，该指令的具体解释见CC26XX TRM 23.3.3.1.8 C【www.ti.com/…/swcu117h.pdf】
请问你的诉求是进行certification test吗？可以参考这边的FCC test： processors.wiki.ti.com/…/FCC_ETSI_Test
