Programming an STM32F103 board using its USB port (Blue Pill) While the $2 board is cheap and very commonly found, getting up and running is slightly convoluted. In this example I have setup two channels to be read via the ADC with the plan of having these automatically buffered into RAM for me. I can download it ok, but the display is just completely blank. In this tutorial I will talk about ADC (Analog to Digital Converter). Hi-Tech C I2C Master Example Code. In this view, it is not possible to set the baud rate, data size, endianness, prescaler, clock polarity, etc. To program this board using a PC and the Arduino IDE. I don't have the space for it here. Quality checked with Grammatech’s Code Sonar static analysis tool STM32Cube Distributions STM32Cube is distributed on a per device family basis. The ADXL345 is a complete 3-axis acceleration measurement system with a selectable measurement range of ±2 g, ±4 g, ±8 g, or ±16 g. For example in direct marketing for CRM I once had only a fraction of 3% of the target variable in the data source.
