"Chip_UART_ReadRB" only receiving half data

sagarpatil — Wed, 03 May 2017 11:11:48 GMT

Hi all,

I have to receive 32 bytes form one of the sensor but i am only able to receive 16 bytes

code snippet:-

uint8_t data[32]={0};

while(!Chip_UART_ReadRB(LPC_UART2,&rxring_2,data,32)); --->only 16 bytes read

even if i use below function:-.

while(!Chip_UART_Read(LPC_UART2,&rxring_2,data,32)); ---->only 16 bytes read

but if i use

while(!Chip_UART_ReadBlocking(LPC_UART2,data,64)); --->read bytes 32 bytes

any known error please let me know it will be helpful
