Prototype[编辑]
int32_t WINAPI VSI_WriteBytes(int32_t DevType,int32_t DevIndex,int32_t SPIIndex,uint8_t *pWriteData,uint16_t Len);
Parameter[编辑]
DevType:Device type code. For detail, please refer to Device Type Definition Table.
DevIndex:Device index number. Index number 0 indicates only one device is connected with computer. In case multiple devices are connected, set index number corresponding to the devices required to be opened.
SPIIndex:Channel number of chip selection signal to be output during data writing. Any value between 0 – 4 is applicable.[编辑]
pWriteData:Data buffer base address.[编辑]
Len:The number of written data bytes with 10200 up to most.[编辑]
Return code:Program execution state. Parameter 0 indicates related function executes successfully. For other return codes' definition, please refer to Error Code Definition Table.[编辑]
Example[编辑]
#include <stdio.h>
#include "ControlSPI.h"
int ret;
uint8_t WriteDataTemp[512]={0};
WriteDataTemp[0] = 0x02;
WriteDataTemp[1] = 0x00;
WriteDataTemp[2] = 0x00;
WriteDataTemp[3] = 0x00;
for(i=4;i<(256+4);i++){
WriteDataTemp[i] = i-4;
}
ret = VSI_WriteBytes(VSI_USBSPI,0,0,WriteDataTemp,256+4);
if (ret != ERR_SUCCESS){
printf("Page program start error :%d\n",ret);
return ret;
}else{
printf("Page program start success!\n");
