I am in charge of SPRESENSE support for Sony.

I will answer your inquiry about the TFT screen delay.

"Regarding this matter, as a result of the recent release of ""v1.2.0"", the power saving response was made
" It affected the deprecated API setClockDivider() on the SPI.
This causes the SPI to have a forward delay of
in libraries using this API. It has occurred.

This symptom is expected to improve in the next release.

Also,
with Adafruit TFT library without deprecated APIs Arduino sketch will also be available soon.

Thank you for your continued support at SPRESENSE.
