Simplifying MCU Programming with LED as Light Sensors When designing a microcontroller-based product, it is crucial to include a programming connector on the PCB. Without it, flashing the firmware to the MCU becomes impossible. However, this connector can take up precious board space, which is a significant issue for size-constrained designs. To address this, designers often use techniques like test points with specialized jigs or… |
