AjK | 0:055897ab699b | 73 | * |
AjK | 0:055897ab699b | 74 | * The MAX3100 librray is designed to allow the easy attachment of additional |
AjK | 0:055897ab699b | 75 | * serial ports to the Mbed. We all know that the Mbed already has 3 potential |
AjK | 0:055897ab699b | 76 | * serial ports. But maybe you need more ports or maybe you need to use the Mbed |
AjK | 0:055897ab699b | 77 | * pins for an alternative function. The MAX3100 may well be able to help in |
AjK | 0:055897ab699b | 78 | * situations like these. |
AjK | 0:055897ab699b | 79 | * |
AjK | 0:055897ab699b | 80 | * Each MAX3100 device you create in is TX/RX buffered with 32 characters in a circular |
AjK | 0:055897ab699b | 81 | * buffer system. |
AjK | 0:055897ab699b | 82 | * |
AjK | 0:055897ab699b | 83 | * The MAX3100 uses at least one Mbed SPI port and additional DigitalOut and InterruptIn |
AjK | 0:055897ab699b | 84 | * pins to work. However, you can attach multiple MAX3100 devices to a single SPI "bus". |
AjK | 0:055897ab699b | 85 | * |
AjK | 0:055897ab699b | 86 | * For more information on attaching multiple devices see all the examples listed below. |
