Hello Cemetech,
It's been a while ... I have been working on Oxygen's input routine and need some help / explanations. I have currently set up the basic functionality of text and number input. But I also want to input math characters like basic operations (+, -, /, *, ^ , `,`) and parenthesis. Could someone point me to documentation or whatnot? I'll be extremely grateful.
Current (character encoding) code:
Code:
// Keys[0] = Upper Case Alpha | Keys[1] = Lower Case Alpha | Key[2] = Numerical
const char *keys[3] = {"\0\0\0\0\0\0\0\0\0\0\0WRMH\0\0?\0VQLG\0\0.ZUPKFC\0 YTOJEB\0\0XSNIDA\0\0\0\0\0\0\0\0\0",
"\0\0\0\0\0\0\0\0\0\0\0wrmh\0\0?\0vqlg\0\0.zupkfc\0 ytojeb\0\0xsnida\0\0\0\0\0\0\0\0\0",
"\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0-\x33\x36\x39)\0\0\0.\x32\x35\x38(\0\0\0\x30\x31\x34\x37,\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"};
// ... Keystrokes code below
I am assuming that I should change the string encoding on the Key[2] but to what exactly, I don't know where to find font encoding and where to look?
Assuming this is for C strings and not tokens, you can type most characters directly into the string (The only ones you need to worry about are really '\' and numbers, and even then the numbers are only an issue if you started an escape sequence with '\' already.
If you do need to encode more characters, you could check an ASCII table, such as one on this page:

Thank you! I assumed it was ASCII characters but thought it would be encoded differently because it was the TI-84PCE.
I came up with a temporary fix:
Code:
if (oxy_stringinput.type == 2 && oxy_stringinput.charsamount - 1 != oxy_stringinput.max_char)
{
char* append_str = NULL;
switch (skKey)
{
case sk_Add:
append_str = "+";
break;
case sk_Sub:
append_str = "-";
break;
case sk_Div:
append_str = "/";
break;
case sk_Mul:
append_str = "*";
break;
case sk_Comma:
append_str = ",";
break;
case sk_LParen:
append_str = "(";
break;
case sk_RParen:
append_str = ")";
break;
case sk_Sin:
append_str = "Sin(";
break;
case sk_Cos:
append_str = "Cos(";
break;
case sk_Tan:
append_str = "Tan(";
break;
case sk_Recip:
append_str = "^-1";
break;
case sk_Square:
append_str = "^2";
break;
case sk_Log:
append_str = "Log(";
break;
case sk_Ln:
append_str = "Ln(";
break;
case sk_Power:
append_str = "^";
break;
}
if (append_str)
{
oxy_stringinput.charsamount += strlen(append_str);
strcat(oxy_stringinput.text, append_str);
}
}
