Howdy,
today I have had a go at W0EB¡¯s firmware version together with a I2C LCD display. Using the I2C bus frees up a number of digital and analog lines. A dedicated digital line is used for straight key input (I am using an external keyer). Also, using software interrupts improves keying responsiveness. I no longer have missing dits and dahs¡
One thing I am missing in this firmware version: there is no way to set PTT delay, that is the time it takes to go from transmit to receiver. It is much to long, especially for contesting.
It looks like it is hardcoded:
#define CW_TIMEOUT (350l)
in ubitx.h
Regards,
Joop PG4I

On??webpage is NANO software that implements interrupt driven CW generation.? Also
eliminates the voltage divider scheme.? Also eliminates the need to switch between straight key?
