3 Architecture
Figure 3.19: The UART TTL module.
Connector 2 (MORS2) This is a connector which can be used to connect the periph-
erals to the first CAN module. The meaning of the various pins is the following: 1 -
CAN+; 2 - CAN-; 3 - GND.
Connector 4 (MORS4) This is a connector which can be used to connect the periph-
erals to the second CAN module. The meaning of the various pins is the following: 1 -
CAN+; 2 - CAN-; 3 - GND.
Connector 5 (MORS5) This is a connector which can be used to connect the periph-
erals to the I2C module. The meaning of the various pins is the following: 1 - Data; 2 -
Clock; 3 - GND.
Connector 6 (MORS6) This is a connector which can be used to connect the periph-
erals to the SPI module. The meaning of the various pins is the following: 1 - 1 - Data
Out; 2 - Data In; 3 - Clock; 4 - Chip Select; 5 - GND.
UART TTL module
This module can be used to export the UART pins linked to the UART peipherals
on the dsPIC by using signals which are compatible with TTL electronic equipments
(see Figure 3.19). Moreover, the module has a set of components which are used to
protect the microcontroller pins from input signals which are not compatible with the
specifications.
The module has four jumpers named JP1, JP2, JP3 and JP4 which can be used to put
in high impedance respectively the RX, CTS, TX and RTS signals. Figure
3.20
shows
the module layout with the location of the various jumpers.
RS232 module
This module can be used to export the UART pins linked to the UART peipherals on
the dsPIC by using signals which are compatible with the RS232 standard (see Figure
3.21).
