編譯后出現(xiàn)User\main.c(57): warning: #167-D: argument of type "char" is incompatible with parameter of type "char *"
強(qiáng)制類型轉(zhuǎn)換還是無法消除，請大佬指點(diǎn)
相關(guān)代碼如下：
NEMA_MSG gps;
while(1)
{
if(DMA_RxFlag)
{
DMA_RxFlag = 0;
GNRMC_Analysis(&gps,(uint8_t*)usart3_dma_buf);
HMI_Send_TxtIntVar("page0.t0",gps.utc.year);
HMI_Send_TxtIntVar("page0.t2",gps.utc.month);
HMI_Send_TxtIntVar("page0.t4",gps.utc.date);
HMI_Send_TxtIntVar("page0.t18",gps.utc.hour);
HMI_Send_TxtIntVar("page0.t19",gps.utc.min);
HMI_Send_TxtIntVar("page0.t20",gps.utc.sec);
HMI_SendTxDblvar("page0.t10", gps.longtitude/100000);
HMI_SendTxtStrVar("page0.t12",gps.E_W); //這句有警告
HMI_SendTxDblvar("page0.t13",gps.latitude/100000);
