QEI
The Quadrature Encoder Interface (QEI) module provides the interface to incremental encoders for
obtaining mechanical positional data.

qei_get_count( )
Relevant Preprocessor:
None
Relevant Interrupts :
#INT_QEI
Relevant Include Files:
None, all functions built-in
WRITE_ROM_MEMORY
ERASE_PROGRAM_EEPROM
WRITE_PROGRAM_EEPROM
WRITE_PROGRAM_MEMORY
ERASE_PROGRAM_EEPROM
WRITE_ROM_MEMORY
Configures the QEI module.
Returns the status of the QUI module.
Write a 16-bit value to the position counter.
Reads the current 16-bit value of the position counter.
Interrupt on rollover or underflow of the position counter.
- Writes any number of bytes, will erase a
block whenever the first (lowest) byte in a
block is written to. If the first address is not the
start of a block that block is not erased.
- Erases a block of size
FLASH_ERASE_SIZE. The lowest address
bits are not used.
- Writes 3 bytes, no erase is needed.
- Writes any numbers of bytes, bytes
outside the range of the write block are
not changed. No erase is needed.
- While writing, every fourth byte will be
ignored. Fill ignored bytes with 0x00.
This is due to the 32 bit addressing and
24 bit instruction length on the PCD
devices.
- Writes any numbers of bytes, bytes
outside the range of the write block are
not changed. No erase is needed.
- Erase a block of size
FLASH_ERASE_SIZE. The lowest
address bits are not used.
