How to use SPI in stm32f103c8t6?
A simple project for demonstrating SPI in STM32F103C8T6 MCU based STM32 Blue Pill Board is implemented here. The STM32 is acting as master in the SPI Communication while Arduino UNO is used as a slave device. When a button is pressed in the master i.e. STM32, an LED will light up on Arduino board.
Can you connect Arduino Uno to STM32 blue pill board?
Similarly, when the Push Button connected to Arduino UNO is pressed, the LED on STM32 Blue Pill Board will be turned ON. You can extend this project and use 16×2 LCDs with both STM32 Blue Pill Board and Arduino UNO and display some information.
Where are the Mosi pins on the STM32 SPI?
An oscilloscope capture of the infinite loop yields the following result where yellow is SCK and blue is MOSI for SPI1 (CN7 pins 10 and 14 for the nucleo-f767zi). The number of clock cycles is consistent with the 4 bytes being sent using the transmit function however there is no actual data on the MOSI pin.
What kind of microcontroller is stm32f103c8t6 blue pill?
In this project, we will take a quick look at the STM32F103C8T6 Development Board, which is based on an ARM Cortex-M3 Microcontroller from STMicroelectronics.
How can I connect a STM32 to an Arduino?
Then connect the corresponding pins of each board i.e. MOSI pin on STM32 (PA7) to MOSI Pin on Arduino (Digital IO 11), MISO pin on STM32 (PA6) to MISO Pin on Arduino (Digital IO 12), SCLK pin on STM32 (PA5) to SCK Pin on Arduino (Digital IO 13) and SS pin on STM32 (PA4) to SS Pin on Arduino (Digital IO 10).
How is SPI used in a microcontroller?
SPI, which is short for Serial Peripheral Interface, is one of the frequently used communication protocols for transfer of data between a Microcontroller and a wide range of peripheral devices like Flash Memories, EEPROMs, SD Cards, Sensors, LCDs, etc.
How many pins does the stm32f030c8 microcontroller have?
A comprehensive set of power-saving modes allows the design of low-power applications. The STM32F030x4/x6/x8/xC microcontrollers include devices in four different packages ranging from 20 pins to 64 pins.
How are potentiometers connected to Arduino and STM32?
Two Potentiometers are also connected with STM32 (PA0) and Arduino (A0) to determine the sending values (0 to 255) from master to slave and slave to master by varying the potentiometer. Comparing SPI bus in Arduino & STM32F103C8 Blue Pill board, STM32 has 2 SPI bus in it while Arduino Uno has one SPI bus.
