Handling 9th-bit SPI Transfer Limitation on ESP32-S3?

Open YutongGu opened this issue 5 months ago • 0 comments

Hi there,

First of all, this is awesome work and exactly what I'm looking for. I'm trying to port this library for my project which attempts to program an STM32 microcontroller via SWD. I discovered that there is a hardware bug in ESP32-S3 which causes transfer sizes of 8n+1 bits to always transmit a 0. See here.

My question is: does this library account for this limitation and if not, would that prevent me from successfully programming another microcontroller?

Thank you!!
