* add change_reciver2sender()/change_sender2reciver()
This is a change to improve readability.
* txled, rxled off in matrix_init()
* add serial_send_packet() / serial_recive_packet()
This is a change to reduce object size.
* add serial_low() at ISR() top
* add __attribute__((always_inline)) to some functions
* modify serial_send_packet()/serial_recive_packet()
A little, object size reduction.
A little, speedup.
* add debug code to helix/serial.c
* Adjust sampling timing of serial signal being received
* add split_scomm.c/split_scomm.h and change serial.c/serial.h
serial.c was divided into 2 layers, split_scom.c and serial.c.
The upper layer split_scomm.c is called from matrix.c.
The lower layer serial.c accesses the hardware.
* add split_scomm.c/split_scomm.h into helix/rev1
* reduce object size helix/rev2/matrix.c
* remove checksum check, add parity check
* force occur parity error for test
* parity test ok. remove test code
* change some comment & add skip code when buffer_size == 0
* serial.c: multiple types of transaction support
Add 4 bits transaction-type field at packet top.
Select Transaction Descriptor Table entry by transaction-type.
* helix serial master-slave transaction optimize
Using multi-type transaction feature of serial.c, communication contents between master slaves were optimized.
* add debug code for retry
* add comment into each config.h
* fix ISR status drop
* add a debug macro 'debug_retry_chg()'
* reduce led_test size
* remove debug code from helix/serial.c and etc.
* helix:five_rows change TAPPING_TERM value 140
* Improved compatibility with let's split of serial.c. Finish helix/serial.c improvement.
- The difference with the original let's split's serial.c
- It's high-speed about 4 times.
- Stable bi-directional data transfer. (Helix need master to slave transfer)
- serial.h was divided 2 files, serial_config.h and sereial.h
- With multiple types of transaction support, communication contents can be optimized. (NEW flexible API)
- USE OLD Simple APIs (compatible with let's split serial.c)
- files :
- serial_config.h -- hardware configuration (need include by config.h)
- serial.c/serial.h -- serial communication
- USE NEW flexible APIs. (Support multi-type transaction function.)
serial.c was divided into 2 layers, split_scom.c and serial.c.
The upper layer split_scomm.c is called from matrix.c.
The lower layer serial.c accesses the hardware.
- files
- split_scomm.c -- communication buffer is defined in here. call by matrix.c.
- split_scomm.h -- buffer size is defined in here. include by matrix.c, split_util.c
- serial_config.h -- hardware configuration (need include by config.h)
To use the NEW API, specify #define SERIAL_USE_MULTI_TRANSACTION
- serial.c/serial.h -- serial communication lower layer
- NEW APIs for serial.c / serial.h (The lower layer)

void serial_slave_init(void)
int serial_update_buffers(void)
