STM32F0 Capacitance meter!

Yet another project with my STM32F0 discovery board… A simple capacitance meter! The value of capacitance can be determined by the time that it takes for a capacitor to charge through the resistor. A precise way to do this would involve using two comparators, 4 precision resistors (three for a precise biasing source and one […]

STM32F0 Discovery + AM2302/DHT22

Well tonight has been productive! I’ve managed to get the DS1307 working with my STM32F0 and now the AM2302! I thought that I’d actually done a previous post on interfacing the DHT11 humidity and temperature sensor but it turns out I hadn’t! The method of operation and data transfer is pretty much the same so […]

STM32F0 Frequency counter!

So we’ve finally got our second semester project briefs and it has been declared that we need to build a half duplex one direction communication system! Obviously, as its a project given by the university, it can’t be as easy as sending USART down a cable and receiving it, requiring pretty much no effort… at […]
