Re: [softrock40] USB I2C Interface Plea for Mercy
- Hi Charles,
The new firmware is default using ABPF (automatic band pass filter) enabled. The ABPF is using the same I/O lines ad the TX and CW on the USB I2C.
Download the CfgSR <http://home.ict.nl/~fredkrom/pe0fko/CFGSR/> and disable the APBF (the setting is saved in eeprom).

To the group:
A couple of months ago I purchased two of the USB I2C kits. I had purchased a couple several years ago which used the ATTINY 45 chips and they worked great.
I finally got around to building one of the current kits which uses the ATTINY 85 chip. The version of software is reported as\\PE)FKO-2.0.
The USB connection works ok as well as frequency setting. However, I have a problem with the PTT signal. When I use the interface with Rocky 3.6, the PTT goes high and stays high regardless of what I do with Rocky.
I have replaced the ATTINY 85 in the new interface board with one of my ATTINY 45 chips and all works well with the PTT signal. The version of this software is Beta1.1.
I have reviewed the softrock40 group messages to see if anyone is having this problem but I got negative results.
Any ideas about what my problem may be?
