# 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](https://github.com/pvvx/TlsrComSwireWriter/blob/master/schematicc.gif)

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.
