Watch short videos about stm32 i2c dma example on Likee. So it would be great to learn about communication between STM32 and Arduino by using SPI & I2C bus. The advantage of a tool such as Keil or IAR is that they support all manufacturer's ARM Cortex-M parts. I2C bus sniffer 1-wire sniffer AVR910 programmer. A github repository will be the best. They all build bugs into their stuff. To disable the BME280 I2C simulator and use the actual I2C port to connect to a real BME280 I2C module, check the instructions for "Enabling I2C Interface on STM32 Blue Pill". The STM32L5 is based on Arm® Cortex-M33 and TrustZone® technology combined with STMicroelectronics security implementation. 4) PERIPHERALS and INTERFACES Which peripherals and interfaces do you need for your project ?
