-------- | |||||
Singnal: Asynchronous, Positive logic, 19200baud, Least bit first | |||||
Frame format: 1-Start bit(Lo), 8-Data bits, Odd-Parity, 1-Stop bit | |||||
This converter uses software method for testing purpose. AVR UART engine will work better. | |||||
Build Firmware | |||||
-------------- | |||||
Just use 'make' | |||||
$ cd pc98_usb | |||||
$ make | |||||
Then, load the binary to MCU with your favorite programmer. | |||||
