Hi, all,

Now I am writing a 8051 assembly program which needs to implement transferring some .hex files through UART. I don't know how to implement this? How to read in a .hex file, divide the file into several small blocks, each block is no more than 16
bytes, each block (added by a header byte and a checksum byte) is viewed as a transfer block. One transfer block can be sent out at one time.
Is that it would be easier to implement this kind of file operation in C or VB?
If you have any idea how to implement this in Assembly or C, If you have a sample program in Assembly or C, pls give me some advice.

Thanks a lot. Look forward to your speedy response.

Best regards,
Billy
