unsigned short Soft_Uart_Read(unsigned short *error);

Returns Returns a received byte.

Description Function receives a byte via software UART. Parameter error will be zero if the

transfer was successful. This is a non-blocking function call, so you should test the

error manually (check the example below).

Requires Soft UART must be initialized and communication established before using this func-

tion. See

Soft_Uart_Init.

Example

// Here’s a loop which holds until data is received:

data = Soft_Uart_Read(&error);

while (error);

// Now we can work with it:

if (data) {...}

Prototype

void Soft_Uart_Write(char data);

Description Function transmits a byte (data) via UART.

Requires Soft UART must be initialized and communication established before using this func-

tion. See Soft_Uart_Init.

Be aware that during transmission, software UART is incapable of receiving data – data

transfer protocol must be set in such a way to prevent loss of information.

Example

char some_byte = 0x0A;

...

Soft_Uart_Write(some_byte);
