Shifting level IC  Certainly! Level shifting ICs are used to convert signals from one logic level to another, allowing communication between devices operating at different voltage levels. Here's a list of some common level shifting ICs along with their applications and features: TXB0108 : This is a bidirectional level shifter with eight channels. It can translate signals between 1.2V and 3.6V. Applications include UART, SPI, I2C, and GPIO level shifting between low-voltage microcontrollers and sensors or other peripherals. SN74LVC1T45 : A single-bit, low-voltage level translator with direction control. It can shift signals between 1.2V and 5V. Common applications include bidirectional level shifting for I2C buses, GPIO expansion, and interfacing low-voltage microcontrollers with 5V devices. PCA9306 : A dual bidirectional I2C-bus and SMBus voltage-level translator. It operates between 1.2V and 3.3V. This IC is commonly used for level shifting in I2C communication between devices wit

  In the STM32 microcontroller series, including the STM32G0B1RET6, the alternate function mapping for GPIO pins (AF0 to AF7) refers to the various peripheral functions that each pin can be configured to serve. You're partially correct in your assessment. Generally, lower alternate function numbers (AF0, AF1, AF2, etc.) tend to represent more common and basic functions, while higher alternate function numbers (AF7, AF8, etc.) often correspond to more advanced or specialized functions. However, it's not necessarily true that higher AF numbers are inherently harder to configure. The difficulty of configuring a particular alternate function depends on several factors: Complexity of the Peripheral : Some peripherals associated with higher alternate functions might have more complex configurations or additional settings compared to simpler peripherals associated with lower alternate functions. Availability of Documentation and Examples : Peripherals with more common alternate functi
