Seeeduino XIAO RP2040 outputs wrong CRC in packet #93

I wrote a simple arduino sketch to ping ID#1 for the Seeeduino XIAO and it works great. When I compile the exact same sketch for the XIAO RP2040 the output is different on the CRC value in packet as follows:

Seeeduino XIAO = "FF FF FD 0 1 3 0 1 19 4E" (which is correct and the dynamixel responds to)

Seeeduino XIAO RP2040 = "FF FF FD 0 1 3 0 1 2D 1" (wrong CRC?)

Can you guys look into this?

Looks like Seeeduino folks fixed this in latest board library version. Not an issue anymore.

@Deezmaker Missing the last couple bytes is usually due to the prematured change of the TX/RX direction. Glad that this has been fixed.
