Created page with "Write/Read block data in USB-SPI master mode. ==== Prototype ==== int32_t WINAPI VSI_BlockWriteReadBytes(int32_t DevType,int32_t DevIndex,int32_t SPIIndex,uint8_t *pWriteData..."

New page

Write/Read block data in USB-SPI master mode.

==== Prototype ====
int32_t WINAPI VSI_BlockWriteReadBytes(int32_t DevType,int32_t DevIndex,int32_t SPIIndex,uint8_t *pWriteData,uint16_t WriteBlockSize, 
uint8_t *pReadData,uint16_t ReadBlockSize,uint16_t BlockNum,uint32_t IntervalTime);

==== Parameter ====
'''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''':SPI channel index number. Index 0 indicates channel 0,Index 1 indicates channel 1, ... 
'''pWriteData''':Buffer base address of data to write. 
'''WriteBlockSize''':Data bytes pointer to write in master mode. 
'''pReadData''':Buffer base address of data to read. 
'''ReadBlockSize''':Data bytes pointer received in master mode. 0 indicates no data has been received. 
'''BlockNum''':Block number to read. 
'''IntervalTime''':Interval time to execute write and read. 

==== Return code ====
Program execution state. Parameter 0 indicates related function executes successfully. For other return codes' definition, please refer to Error Code Definition Table.
==== Example ====
#include <stdio.h>
#include "ControlSPI.h"
int ret;
uint8_t pWriteData[1024] = {0};
uint8_t WriteBlockSize=128;

uint8_t pReadData[1024] = {0};
uint8_t ReadBlockSize=128;
uint8_t BlockNum=1;
uint16_t IntervalTime=100;

for(uint16_t i=0; i<16){
write_buffer[i]=i;
}

ret = VSI_BlockWriteReadBytes(VSI_USBSPI, 0, pWriteData, WriteBlockSize, pReadData, ReadBlockSize, BlockNum, IntervalTime);
if (ret != ERR_SUCCESS){
printf("Block write/read data error!\n");
return ret;
}
if(ReadBlockSize){
for(uint16_t i=0; i<ReadBlockSize; i++){
printf("%x\n", pReadData[i]);
}
}
