µC goes analog

Your average embedded system will be primarily composed of digital components. However, analogue components are also necessary for filtering and amplifying signals, among other things. Cypress PSoCs combine a microcontroller with analogue functional blocks. A development kit such as the CY3270 forms a good starting point for rapid familiarisation with these ICs. You can buy the CY3270: PSoC First Touch’ starter kit for around £ 15 (25 euros).
