I'm looking for a way to convert a hexadecimal string to a ULONG variable.

Hello.

When I read the serial number of a DS18B20, it outputs a 12-digit string.
I'd like to convert this to a ULONG variable.
Is there a quick and easy way to do this?

Thank you.

Re: Question about communication between two mcu via spi

When I send each variable to serial, the data does not come out correctly.

The order of each variable is .
123 124 125 126 127 128

This is the order in which the values of the variables are printed.
128 123 124 125 126 127

Thank you.

One piece of data is read successfully.

However, the second piece of data is displayed as the requested local address.

Any other ideas?
