John Ackermann, N8UR, just released an update to the Arduino firmware for the TICC. The new version is 20200412.1. It, along with all the TICC source code and documentation, is available at:
In addition to a few bug fixes and cleanups, there are a couple of more noticeable changes that are discussed in the LATEST_CHANGES.txt file.
One item changes current behavior: data is now output with 11 decimal places (10 ps resolution) instead of the previous 12 (1 ps resolution). The last digit was simply noise, and it contributes to an esoteric issue I don’t need to go into here. So you’ll see one less decimal place in the output, but the useful resolution hasn’t changed.
To install the new firmware you can use the Arduino IDE, but that’s a lot of download and hassle if you’re not interested in actually working with the source code. As an alternative,
has hex files of the new version (TICC.ino-20200412.1.hex) that can be uploaded directly into the TICC via USB, as well as install tools for doing so under Windows and Linux. These don’t require installing the Arduino IDE.
NOTE: TICC units currently shipped by TAPR still have the prior firmware version installed; unfortunately it’s not feasible for us to update the firmware before shipping.
