Criar matriz de byte atraves de uma String

#cc

Galera, seguinte tenho uma imagem que é guardada em uma matriz do tipo byte, ela é assim:

const byte RPrint [] = {

0x01, 0x01, 0x01, 0x31, 0x00, 0x30, 0x38, 0x30, 0x02, 0x20, 0x89, 0xE0, 0xE3, 0xF0, 0xF9, 0xFD,

};

só que eu preciso construir esta matriz dinamicamente, este conteudo está nums string tipo

StringImagem = ' 0x3F, 0x3F, 0x3F, 0x3F, 0x3F, 0x3F, 0x3F, 0x3F, 0x7F, 0x3F, 0x3F, 0xBF, 0x3F, 0x7F, 0x3F, 0x3F' ....

como faria para montar cada codigo hexa dentro de uma posição de minha matriz

tipo eu tenho ela criada zerada byte RPrint [];

tem alguma maneira de fazer isso?

pq eu uso a variavel RPrint para imprimir a imagem....

Obrigado desde jah!

memset resolve o problema?

DarkDucke· 28 de mai.

Não, creio que você não entendeu, memset vai zerar a variavel, eu preciso pegar o conteudo da string que esta entre as virgulas "," e coloca em cada posição de minha matriz byte, isto dinamicamente!

Obrigado msms assim!

:s acho q fiquei leigo naum entendi muito, tente me explicar melhor oq qr!

Que eu saiba,memset só zera a memoria se você mandar encher de zero e não existe tipo byte em C.

Use strtok e malloc.

DarkDucke· 28 de mai.

eu sou leigo em C, em outro forum um colega postou uma função, deu certo +- agora o problema acho que ta no tipo de variavel, veja a função:

/ FUNÇÃO PARA IMPRESSÃO DE LOGO DINAMICA /
void MENU_LOGOS(void)
{

 int n;
 char frase[] = "0x01, 0x01, 0x01, 0x31, ...";
 const byte aRPrint [] = {0x00, 0x00, 0x00, 0x00, 0x00,...};
 char * palavra;
 byte xRPrint [] = {0x00, 0x00, 0x00, 0x00, 0x00,...};

 int i = 0;
 palavra = strtok(frase, ", ");
 while (palavra!=NULL) {
 xRPrint[i] = (byte)palavra;
 i++;
 palavra = strtok(NULL, ", ");
 }

 PrintImage((byte *)aRPrint, 5, 128, 8);
 PrintImage((byte *)xRPrint, 5, 128, 8);
}

/ FIM IMPRESSÃO LOGO DINAMICA / a Imagem que ta na variavel aRPrint imprime normalmente, a imagem que ta na variavel xRPrint imprime um monte de sujeira após passar o conteudo da string frase para ela... creio que os codigos hexa não estão indo como hexa, a função PrintImage(); não consegue imprimir a imagem...

alguma ideia? conseguirao me entender agora?

Obrigado novamente!

Entendi!

Você está querendo é transformar a string "0x01" em byte!!!!

Isso não funciona! Você primeiro terá que achar o valor em byte do valor hexadecimal (string).

E depois passar para o array!

bom vagando pelos fóruns de C/C++ vi q nosso amigo DarkDucke resolveu seu problema!
