c59513fd84fb Initial commit of STM32 test code. Daniel O'Connor <darius@dons.net.au> parents: diff changeset	11 * Notes:
c59513fd84fb Initial commit of STM32 test code. Daniel O'Connor <darius@dons.net.au> parents: diff changeset	12 * - This driver is intended for STM32L1xx families devices only.
c59513fd84fb Initial commit of STM32 test code. Daniel O'Connor <darius@dons.net.au> parents: diff changeset	13 * - There is no I2C EEPROM memory available in STM32L152-EVAL board,
c59513fd84fb Initial commit of STM32 test code. Daniel O'Connor <darius@dons.net.au> parents: diff changeset	14 * to use this driver you have to build your own hardware.
c59513fd84fb Initial commit of STM32 test code. Daniel O'Connor <darius@dons.net.au> parents: diff changeset	15 * ===================================================================
c59513fd84fb Initial commit of STM32 test code. Daniel O'Connor <darius@dons.net.au> parents: diff changeset	16 *
c59513fd84fb Initial commit of STM32 test code. Daniel O'Connor <darius@dons.net.au> parents: diff changeset	17 * It implements a high level communication layer for read and write
c59513fd84fb Initial commit of STM32 test code. Daniel O'Connor <darius@dons.net.au> parents: diff changeset	18 * from/to this memory. The needed STM32 hardware resources (I2C and
c59513fd84fb Initial commit of STM32 test code. Daniel O'Connor <darius@dons.net.au> parents: diff changeset	19 * GPIO) are defined in stm32l152_eval.h file, and the initialization is
c59513fd84fb Initial commit of STM32 test code. Daniel O'Connor <darius@dons.net.au> parents: diff changeset	20 * performed in sEE_LowLevel_Init() function declared in stm32l152_eval.c
c59513fd84fb Initial commit of STM32 test code. Daniel O'Connor <darius@dons.net.au> parents: diff changeset	21 * file.
c59513fd84fb Initial commit of STM32 test code. Daniel O'Connor <darius@dons.net.au> parents: diff changeset	22 * You can easily tailor this driver to any other development board,
c59513fd84fb Initial commit of STM32 test code. Daniel O'Connor <darius@dons.net.au> parents: diff changeset	23 * by just adapting the defines for hardware resources and
c59513fd84fb Initial commit of STM32 test code. Daniel O'Connor <darius@dons.net.au> parents: diff changeset	24 * sEE_LowLevel_Init() function.
c59513fd84fb Initial commit of STM32 test code. Daniel O'Connor <darius@dons.net.au> parents: diff changeset	25 *
c59513fd84fb Initial commit of STM32 test code. Daniel O'Connor <darius@dons.net.au> parents: diff changeset	26 * @note In this driver, basic read and write functions (sEE_ReadBuffer()
c59513fd84fb Initial commit of STM32 test code. Daniel O'Connor <darius@dons.net.au> parents: diff changeset	27 * and sEE_WritePage()) use the DMA to perform the data transfer
c59513fd84fb Initial commit of STM32 test code. Daniel O'Connor <darius@dons.net.au> parents: diff changeset	28 * to/from EEPROM memory (except when number of requested data is
c59513fd84fb Initial commit of STM32 test code. Daniel O'Connor <darius@dons.net.au> parents: diff changeset	29 * equal to 1). Thus, after calling these two functions, user
c59513fd84fb Initial commit of STM32 test code. Daniel O'Connor <darius@dons.net.au> parents: diff changeset	30 * application may perform other tasks while DMA is transferring
c59513fd84fb Initial commit of STM32 test code. Daniel O'Connor <darius@dons.net.au> parents: diff changeset	31 * data. The application should then monitor the variable holding
c59513fd84fb Initial commit of STM32 test code. Daniel O'Connor <darius@dons.net.au> parents: diff changeset	32 * the number of data in order to determine when the transfer is
c59513fd84fb Initial commit of STM32 test code. Daniel O'Connor <darius@dons.net.au> parents: diff changeset	33 * completed (variable decremented to 0). Stopping transfer tasks
c59513fd84fb Initial commit of STM32 test code. Daniel O'Connor <darius@dons.net.au> parents: diff changeset	34 * are performed into DMA interrupt handlers (which are integrated
c59513fd84fb Initial commit of STM32 test code. Daniel O'Connor <darius@dons.net.au> parents: diff changeset	35 * into this driver).
