The ft6x06 v0.1.2 crate panics when the touch controller reports more than FT6X06_MAX_NB_TOUCH (2) simultaneous touches, which can happen due to electrical noise or ghost touches. This patch applies PR #5 (commit cc352f8) which clamps the touch count instead of asserting, preventing device crashes.

The FT6X06 touch interrupt is active-LOW and requires a pull-down resistor for a defined idle state. Without this, the pin floats and wait_touch_interrupt() never returns properly. The sdio::init() function returns PC1 for touch interrupt use, but was returning it without any pull configuration. Now configures it as pull-down input before returning.
When building a BSP that depends on the HAL, both build.rs scripts were running and potentially conflicting. Now the HAL only generates memory.x when it's the primary package being built. BSPs have their own board-specific memory.x (flash/RAM sizes vary by chip package) and should use that instead of the HAL's generic defaults.
Complete BSP for STM32F469I-DISCO board including: - build.rs with memory.x generation - memory.x for F469 (2M flash, 320K RAM) - Examples: display, touch, SDRAM, GPIO - README with usage instructions - Embed.toml for probe-rs - License (0BSD)
For future AI agents using this HAL: - PIN-CONSUMPTION.md: Documents which 52 pins SDRAM consumes and which remain available (PC1, PC8-12, PD2, PH7). Hardware constraint not obvious from code. - USB-GUIDE.md: USB OTG FS setup with 48MHz PLL48CLK requirement, CDC-ACM pattern, and troubleshooting table. The USB module IS functional (contrary to previous misinformation). - usb_cdc_serial.rs: Working CDC-ACM example that compiles and demonstrates virtual serial port with echo test. - README.md: Updated with correct doc links and USB example. - Cargo.toml: Added USB dev-dependencies (usb-device, usbd-serial, static_cell).
Allows external code to change SDIO clock speed after initialization. This is needed for SDXC cards that require 400KHz for init but can benefit from higher speeds (e.g., 12MHz) for data transfer.
