Can anyone confirm whether my understanding of the following behaviour is correct (and whether there's any way round it):When the built in bootloader has been entered by jumping to it from firmware (i.e. the BOOT0 pin is NOT pulled high), and the boo...

I'm finding that t STUSB4500 drives its I2C SDA line low (for around 1 second) during power up or power down (the device is powered from Vbus only).This prevents all communication with other devices on the I2C bus during this time.Holding STUSB in it...

I'm using STM32F105RBT, and I'm finding that, in certain circumstances, the phase locked loop is failing to become ready.1) Boot (sysclk = HSI @8MHz)2) Set PLL with source=HSI(div2) and multiplier=93) Enable PLL4) Wait for PLL ready (waits forever he...

From the point of view of firmware in microcontroller, which is communicating with STUSB4500 by I2C, how can it find out what PDO (voltage and current) has been negotiated with the power source.I am particularly interested in maximum current so the m...
