Hi @guohui Success!!! Thanks!!! I will do some tests during next days, I will come back with results.I noticed that floating point math was not implemented ... is it planned for the next release or not at all?
The core MCU is cortext-M3, which is without hardware floating functionality.
I know but some SW math library would be useful... any plans?
I would like to mark this post first and try implementing it in the next or later release as we can.
After FW uploading, how to upload the python script to RedBear Duo
Still I did not upload the FW also because I want to backup the current FW
