Keyboard: Helix serial.c, split_scom.c bug fix and update (#4191)
* helix/serial.c add support PD1,PD3,PE6 and configuration simplify * Add comment about ATmega32U4 I2C * Add compile time check for ATmega32U4 I2C * change TAB code to 8 SPACE code * Helix serial.c PORTD,PD0 test. OK OK PD0 - PD1 OK PD2 - PD3 - PE6 * Helix serial.c PORTD,PD1 test. OK OK PD0 OK PD1 OK PD2 - PD3 - PE6 * Helix serial.c PORTD,PD3 test. OK OK PD0 OK PD1 OK PD2 OK PD3 - PE6 * Helix serial.c PORTE,PD6 test. OK OK PD0 OK PD1 OK PD2 OK PD3 OK PE6 * Helix serial.c: PD0,PD1,PD3,PE6 all test end * Helix serial.c: rename SOFT_SERIAL_PORT to SOFT_SERIAL_PIN * Helix serial.c add debug code * Helix serial.c: add transaction ID range check * Helix serial.c debug code update * Helix serial.c debug code update * Helix serial.c: Strict checking of the value of tid. * adjust the delay of serial.c * Helix serial.c: remove debug code * remove EXTRAFLAGS += -DCONSOLE_ENABLE from five_rows/rules.mk tmk_core/common.mk has >ifeq ($(strip $(CONSOLE_ENABLE)), yes) > TMK_COMMON_DEFS += -DCONSOLE_ENABLE * Fix error handling in split_scomm.c * add some comment to serial.c * add some comment about SELECT_SOFT_SERIAL_SPEED
