TlsrComSwireWriter

TLSR826x/825x COM port Swire Writer Utility

Telink SWIRE simulation on a COM port.

Using only the COM port, downloads and runs the program in SRAM for TLSR826x or TLSR825x chips.

SCH

Don't forget to connect GND.

If the module does not have a RESET pin from the chip, then the RTS signal from the COM port can be connected as the module power supply - connect it to +3.3 V of the module.

If the module has a RESET pin, then it is advisable to connect the module power supply to +3.3 V, and connect RESET to RTS.

usage: ComSwireWriter [-h] [--port PORT] [--tact TACT] [--file FILE] [--baud BAUD]
