The $0.10 Microcontroller That Does It All: LCD, Touch, and USB We’ve seen LCDs with touch input before, but what if the LCD itself could be used as a touch sensor? That’s exactly what YouTuber CNLohr has accomplished with his latest project, combining a 7-segment LCD, USB functionality, and touch sensing—all powered by the ultra-affordable CH32V003 RISC-V microcontroller, AKA "The $0.10 RISC V microcontroller". The CH32V003 doesn’t natively support USB,… |

Introduction to Bit Banging: SPI communication via Bit Banging Communication Interfaces are one of the factors that are considered when selecting a microcontroller to be used for a project. The designer ensures that the microcontroller being selected has all the interfaces required to communicate with all the other components to be used for the product. The existence of some of these interfaces, like SPI and I2C on microcontrollers,… |
