SPI Remappable Library
SPI Remappable module is available with these MCUs: 18F2xJ11, 18F4xJ11, 18F2xJ50 and 18F4xJ50. mikroC PRO for PIC provides a library for initializing Slave mode and comfortable work with Master mode. PIC can easily communicate with other devices via SPI: A/D converters, D/A converters, MAX7219, LTC1290, etc.
Library Dependency Tree
Library Routines
SPI_Remappable_Init
Prototype |
void SPI_Remappable_Init(); |
---|---|
Returns |
Nothing. |
Description |
Configures and initializes SPI Remappable module with default settings. Default settings are:
Note :
Before using this library, make sure that Peripheral Pin Select Library is checked in the Library Manager, and that appropriate pins were mapped.
|
Requires |
You'll need PIC MCU with hardware integrated SPI and remappable feature. |
Example |
// Initialize the SPI Remappable module with default settings SPI_Remappable_Init(); |
SPI_Remappable_Init_Advanced
Prototype |
void SPI_Remappable_Init_Advanced(b>unsigned short master_slav, unsigned short data_sample, unsigned short clock_idle, unsigned short transmit_edge); |

Example |
// Set SPI to master mode, clock = Fosc/4, data sampled at the middle of interval, clock idle state low and data transmitted at low to high edge: SPI_Remappable_Init_Advanced(_SPI_REMAPPABLE_MASTER_OSC_DIV4, _SPI_REMAPPABLE_DATA_SAMPLE_MIDDLE, _SPI_REMAPPABLE_CLK_IDLE_LOW, _SPI_REMAPPABLE_LOW_2_HIGH); |
SPI_Remappable_Read
Prototype |
unsigned short SPI_Remappable_Read(unsigned short buffer); |
---|---|
Returns |
Returns the received data. |
Description |
Reads one byte from the SPI bus. Parameters :
|
Requires |
You need PIC MCU with hardware integrated SPI and remappable feature. SPI must be initialized and communication established before using this function. See SPI_Remappable_Init_Advanced or SPI_Remappable_Init. |
Example |
short take, buffer; ... take = SPI_Remappable_Read(buffer); |
SPI_Remappable_Write
Prototype |
void SPI_Remappable_Write(unsigned short data_); |
---|---|
Returns |
Nothing. |
Description |
Writes byte |
Requires |
You need PIC MCU with hardware integrated SPI and remappable feature. SPI must be initialized and communication established before using this function. See SPI_Remappable_Init_Advanced or SPI_Remappable_Init. |
Example |
SPI_Remappable_Write(1); |
