strings/char converting --> uart problem

[Jörg Güldner]

Hi,
I`ve some questions to sending different datas over the uart:
01.) integer (0x41) = tostring$(65) --> how can I managed to get a "A" in the string? How is the way to go back("A" --> 65)?

02.) I send a string "hello" and additional a char(13). In the receiver I use the receive string component with one letter and put the single letters together in a new string.
Background is to check the incoming char(13). How can I managed this?

03.) str1 = numbertohex$(123) shows in the debugger "0x"?

Best regards
Jörg

A string is an array of bytes,
So for example you can place an A as the first character in the string with any of these

Similarly, if you want to look for a carriage return in a string you can compare with 13

It looks like your string length for str3 is not large enough

StringToInt$() expects the string to be a valid number

Code: Select all

str2 = "100"
int2 = StringToInt$ (str2)

Hope that helps,
