![]() ![]() Now that we have a block diagram we can better understand the necessary requirements for the microcontroller. ![]() Blocks in yellow are included in this initial tutorial. If they are supplied from different voltages then you’ll usually need to add in a level shifter. In most cases when two electronic components communicate they need to use the same supply voltage. Including the supply voltage for each functional block it allows you to easily identify all of the supply voltages you’ll need as well as any level shifters. Later, once all of the components have been selected and the required supply voltages are known I like to add the supply voltages to the block diagram. In future tutorials we’ll expand the design to include all of the functionality shown in this block diagram.Ī block diagram should include a block for each core function, the interconnections between the various blocks, specified communication protocols, and any known voltage levels (input supply voltage, battery voltage, etc.). As I mentioned, for this first tutorial we’ll focus just on the microcontroller itself. Block Diagramīelow is the block diagram that we’ll be working from in this tutorial series. With a system-level design the focus is on the higher level interconnectivity and functionality. In engineering, a black box is an object which can be viewed in terms of its inputs and outputs but without any knowledge of its internal workings. A system design treats each function as a black box Before getting into the details of the full schematic circuit design it’s always best to first focus on the big picture of the full system.ĭesigning the system consists mainly of two steps: creating a block diagram and selecting all of the critical components (microchips, sensors, displays, etc.). When developing a new circuit design the first step is the high-level system design (which I also call a preliminary design). I’ll break down the entire design process into three fundamental steps: STEP 1 – System Design STEP 2 – Schematic Circuit Design STEP 3 – PCB Layout Design 2.4 GHz RF transceiver supporting IEEE 802.15.In this step-by-step tutorial you’ll learn how to design your own custom microcontroller board based on the popular STM32 microcontroller from ST Microelectronics.Board-specific features (STM32WB55RG only).Support of a wide choice of Integrated Development Environments (IDEs) including IAR Embedded Workbench ®, MDK-ARM, STM32CubeIDE, and Mbed Studio.Comprehensive free software libraries and examples available with the STM32CubeWB MCU Package.On-board ST-LINK/V2-1 debugger/programmer with USB re-enumeration capability: mass storage, Virtual COM port, and debug port.On-board footprint to mount a CR2032 battery socket.Flexible power-supply options: ST-LINK, USB V BUS, or external sources.Integrated PCB antenna and SMA connector footprint.Board connectors: ARDUINO ® Uno V3 expansion connector ST morpho extension pin headers for full access to all STM32WB I/Os.STM32WB55RG (1-Mbyte Flash memory, 256-Kbyte SRAM, in VFQFPN68 package) or STM32WB15CC (320-Kbyte Flash memory, 48-Kbyte SRAM, in VFQFPN48 package) ultra‑low‑power wireless microcontroller featuring: Dual-core 32‑bit (Arm ® Cortex ®-M4 and dedicated M0+ CPU for real-time radio layer) 2.4 GHz RF transceiver supporting Bluetooth ® specification v5.2. ![]()
