 UART to Microcontroller

Another possible usage of UART is to communicate with another embedded system or

microcontroller. For microcontroller to interface with SK40C, the minimum requirement will

be TTL UART (Universal Asynchronous Receiver and Transmitter) and 5V supply. As for

UART, a minimum of Receiver pin is required to receive command from SK40C.

1. Following sample schematic show SK40C is interface to SKPS. This sample

schematic show UART pin of SK40C (PIC16F877A) is connecting to UART pin of

SKPS. Tx and Rx pin of SK40C should be cross connected to Tx and Rx pin of

SKPS. In other words, Tx pin of SK40C should be connected to Rx pin of SKPS,

while Rx pin of SK40C should be connected to Tx pin of SKPS. No extra component

is necessary between these connections. For details connection, please refer to sample

schematic.
