This was made by PCBWay. I designed it in KiCad. It’s basically four shift registers and LEDs. Since it was my first time seeing a transparent PCB, I designed it to explore how it could be used. It’s not transparent like glass. It’s more like translucent and diffuses light. One advantage is that you canContinue reading “Transparent PCB”

CH32V003 GPIO/Pin modes
Output modes There are two different output modes: Open drain output: GPIO_Mode_Out_OD Push-pull output: GPIO_Mode_Out_PP Input modes There are four different input modes: Floating input: GPIO_Mode_IN_FLOATING Pull-up input: GPIO_Mode_IPU Pull-down input: GPIO_Mode_IPD Analog input: GPIO_Mode_AIN Alternate functions The GPIO can also be configured as an “alternate function”. Used for specific hardware functions like pulse widthContinue reading “CH32V003 GPIO/Pin modes”
CH32V003 Analog Reading
ADC (Analog-to-Digital Converter): Converts an analog signal (such as a voltage) into a digital value that can be processed by a microcontroller. The conversion process typically involves sampling the analog signal at a specific rate and quantizing the signal to produce a digital representation. CH32V003 ADC has a 10-bit resolution. Values 0-1023. DMA (Direct MemoryContinue reading “CH32V003 Analog Reading”
