Quick little 2-layer BGA board with USB HS and SDHC.
Quick little 2-layer BGA board with USB HS and SDHC.
First time doing BGA w/ KiCad, PoE, nonstandard PHY, Ethernet magnetics, writing an Ethernet driver, and using the FreeRTOS+TCP stack.
Is this art?
Compact, battery-powered, and uses ripple counting for encoderless closed-loop motor control. Not perfect, but consistent enough for 0402 parts.
Added core support for the CH32X035 along with USB FS, USB PD, ADC, and UART drivers. Supporting other CH32V parts will be relatively straightforward.
First time using a RISC-V microcontroller, iCE40 FPGA, and an LTC2320 ADC. It streams 8 channels of differential 16-bit 48kHz ADC readings over USB as audio.
Developing for CH32V using 100% open-source components, true to the essence of RISC-V.
While still lacking in many features, I’ve added just enough support to get the LPC845-BRK and my own LIN breakout working.
An easy to deploy hardware and software solution for converting any oven into a Wi-Fi enabled reflow oven. This is just one.
With much more experience under my belt, I challenged myself both in size and processing power in the next version of my lightsaber.
First time trying solar power, PIC, and FRAM.
Recreating patented technology yet again but this time using OSH Park for the PCBs.
