Revision:
1:f30bdcd2b33b
Parent:
0:098463de4c5d 
changed the inputscale from 1 to 7 in analogin_api.c.  This will need to be changed later, and accessed from the main level, but for now this allows the  adc to read a value from 0 to 3.7V, instead of just up to 1V.;

Who changed what in which revision?

group-onsemi 0:098463de4c5d 13 ##### How to use this driver #####
group-onsemi 0:098463de4c5d 14 ===============================================================================
group-onsemi 0:098463de4c5d 15 [..]
group-onsemi 0:098463de4c5d 16 This driver is a generic layered driver which contains a set of APIs used to
group-onsemi 0:098463de4c5d 17 control PCCARD/compact flash memories. It uses the FSMC/FSMC layer functions
group-onsemi 0:098463de4c5d 18 to interface with PCCARD devices. This driver is used for:
group-onsemi 0:098463de4c5d 19
group-onsemi 0:098463de4c5d 20 (+) PCCARD/compact flash memory configuration sequence using the function
group-onsemi 0:098463de4c5d 21 HAL_PCCARD_Init() with control and timing parameters for both common and
group-onsemi 0:098463de4c5d 22 attribute spaces.
group-onsemi 0:098463de4c5d 23
group-onsemi 0:098463de4c5d 24 (+) Read PCCARD/compact flash memory maker and device IDs using the function
group-onsemi 0:098463de4c5d 25 HAL_PCCARD_Read_ID(). The read information is stored in the CompactFlash_ID
group-onsemi 0:098463de4c5d 26 structure declared by the function caller.
group-onsemi 0:098463de4c5d 27
group-onsemi 0:098463de4c5d 28 (+) Access PCCARD/compact flash memory by read/write operations using the functions
group-onsemi 0:098463de4c5d 29 HAL_PCCARD_Read_Sector()/HAL_PCCARD_Write_Sector(), to read/write sector.
group-onsemi 0:098463de4c5d 30
group-onsemi 0:098463de4c5d 31 (+) Perform PCCARD/compact flash Reset chip operation using the function HAL_PCCARD_Reset().
group-onsemi 0:098463de4c5d 32
group-onsemi 0:098463de4c5d 33 (+) Perform PCCARD/compact flash erase sector operation using the function
group-onsemi 0:098463de4c5d 34 HAL_PCCARD_Erase_Sector().
group-onsemi 0:098463de4c5d 35
group-onsemi 0:098463de4c5d 36 (+) Read the PCCARD/compact flash status operation using the function HAL_PCCARD_ReadStatus().
group-onsemi 0:098463de4c5d 37
group-onsemi 0:098463de4c5d 38 (+) You can monitor the PCCARD/compact flash device HAL state by calling the function
group-onsemi 0:098463de4c5d 39 HAL_PCCARD_GetState()
group-onsemi 0:098463de4c5d 40
group-onsemi 0:098463de4c5d 41 [..]
group-onsemi 0:098463de4c5d 42 (@) This driver is a set of generic APIs which handle standard PCCARD/compact flash
group-onsemi 0:098463de4c5d 43 operations. If a PCCARD/compact flash device contains different operations
group-onsemi 0:098463de4c5d 44 and/or implementations, it should be implemented separately.
