Hi, thanks for using my work.
I fixed the bug, please try it.

Hello, I will support to work.

ANT+ USB timeout error
This is an error message by openant, and my program does not handle it specifically. If the ANT+ sensor is paired, you will not get the error message. Do you have any ANT+ sensors? If you don't have any, then I suggest you uninstall openant itself.

Missing fb1 framebuffer
First, which LCD are you using? I've only used Adafruit's PiTFT.
Follow the seller's tutorial and make sure it draws on /dev/fb1.
Here is a tutorial I wrote on PiTFT in Japanese.

Pressure data
Which product do you use for the barometric altimeter?

Hi Simon

Thank you for working on this project!

Display
A temporary solution is to set the resolution to 320x240 in /boot/config.txt, output to /dev/fb0 (HDMI) via linuxfb, and mirror the HDMI output to TFT.

BerryGPS IMU v4
Sorry, I have two BerryGPS IMU v4 boards and both have the same problem.
The first is that the GPS chip antenna doesn't seem to work properly and I need to use a powerful external antenna to get the GPS to work.
The second is that I haven't tried an I2C connection for this GPS, and there doesn't seem to be a suitable python pip package. If possible, use HAT connection (UART+I2C) to get position data from GPSd.
Thirdly, the magnetometer sensor does not work properly. Please give up on the electronic compass. The accelerometer is working, so the auto start/stop with vibration detection works. This works well with GPS tracking.

ANT+ sensor
If you start by checking the connection of the heart rate monitor with Openant's example program, it will be easier to isolate the problem.

If you have any problems, please give your feedback!

Hi Simon,

I fixed the program and closed the issue. Thereby a notification email has been sent to you.

Your work is amazing!
Thank you for making a device with my program.

Please share it with us when you finish it.
Cases are still an area I haven't tackled yet and I'm very interested in your approach.
