Re: Modbus Communication Down

If I leave it on for a long time, it starts working again for a while and then crashes again, repeating the process.

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.

I'm reading them using I2C, but the values aren't being written to the correct variables. I've tried reading them using both the voltage and r...

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.
