#CMSIS-SPI-uDMA-GCC-Tiva-C-TM4C123

This repository developed using CCS with GCC compiler version 4.9.3 which includes 1-CMSIS driver (cmsis) 2-SPI driver (SPID) 3-DMA driver (UDMA) 4-Error handler (ERRH) #TO_BE_DONE 4-Timer driver (TIMD) TO #TO_BE_DONE

##CMSIS Standard driver created by ARM to handle ARM cortex processor plus module cmsis_NVIC created by mbed-OS to handle interrupt vector table

##SPID Higly configurable module To enable certain SPI peripheral,, uncomment its definition and configure the enabled definitions to desired functionality

###void SPID_Init(SPID_SpiPort_T ssix) Initalizer for SPIn according to the configured parameters in the header file

###void SPID_Enable (SPID_SpiPort_T ssix) Enable the SPIn peripheral

###void SPID_Disable (SPID_SpiPort_T ssix) Disable the SPIn peripheral

###SPID_SSI_T SPID_GetEnabledSPI(void) Getter for the currently enabled SPI peripheral

###uint8_t SPID_SSInSendData(uint16_t data) Incase UDMA not used, this API used to send data over Tx of the SPI. If transmission handled successfully the function return SW_OK otherwise SW_NOK

###uint16_t SPID_SSInReceiveData(void) Incase UDMA not used, this API used to receive data from Rx of the SPI.

###SPID_Status_T SPID_GetSSInStatus(void) return the status of current SPI peripheral

##UDMA Used specifically to exchange data with SSI2. Still under development

#Note SPI is current working with UDMA 8 items of 16-bit buffer on Tx and Rx
