Hi all, I am designing a burglar car alarm system with PIC16C54/xt chip. I use an AX5326 encoder for transmitting codes and an AX5327 for decoding in receive.But i have some questions about them: 1.Do you know the manufacturer of AX5326? 2.In many car alarms i have seen they omit the AX5327 chip in rece{ver and they decode with PIC16c54 chip do you know how and is there any source program for doing this? 3.For tranfering PDF files must i use binary or ascii mode? 4.How can i rea the PDF files? Any help from you is appreciated. rgds A.Marami
