* 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) // Soft Serial Transaction Descriptor typedef struct _SSTD_t { uint8_t *status; uint8_t initiator2target_buffer_size; uint8_t *initiator2target_buffer; uint8_t target2initiator_buffer_size; uint8_t *target2initiator_buffer; } SSTD_t; // initiator is transaction start side void soft_serial_initiator_init(SSTD_t *sstd_table); // target is interrupt accept side void soft_serial_target_init(SSTD_t *sstd_table); int soft_serial_transaction(int sstd_index); int soft_serial_get_and_clean_target_status(int sstd_index); - NEW APIs for split_scomm.c / split_scomm.h (The upper layer) move from old serial.c the following buffer and functions serial_slave_buffer[] serial_master_buffer[] void serial_master_init(void) void serial_slave_init(void) int serial_update_buffers(void) define SERIAL_xxxxx_BUFFER_LENGTH move from serial_config.h to split_scomm.h
