Run the example by following the readme. The likner script, startup file, OpenOcd config. I2C or Inter-Integrated Circuit is a multimaster serial single ended bus. The analog peripherals include 12-bit ADCs with 5 MSPS capability and power-saving modes, as well as two 12-bit DACs, two op-amps with built-in Programmable-Gain. The B-L475E-IOT01A Discovery kit for IoT node allows users to develop applications with direct connection to cloud servers. In many microcontroller projects, you need to read and write data. Before you begin, ensure that you can build and debug embedded projects for your STM32 board by following one of our basic STM32 tutorials. Sends sensor data to Sigfox via Wisol Sigfox module on UART. GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together. Since I2C is an open drain concept the VCC level as such is not critical for the operation as long as all components on the bus can accept the voltage on the IO pins and are able to detect the logic levels. As we all know, STM32 doesn't build in EEPROM in the package. Again you need to read it from RAM and continuously write to SPI data register and so on. Example 1 - Promises.
