462FinalProject is an open-source printed circuit board by jkmunson, from the jkmunson/RTOS_POD repository on GitHub. It is a 2-layer board of 30 × 100 mm with 46 parts on 44 nets, routed with 542 tracks and 76 vias.
It is built around the MIC5504-3.3YM5, CL21A106KOQNNNE and MBR0530, with the CR0805-JW-102ELF, BSS84AK,215(ES) and SI2302 among its other parts. Its parts include 8 transistors, 6 capacitors, 6 resistors, 4 ICs and 4 diodes. It belongs with the STM32 boards of this library.
BEGINNING OF NOTES BY WYATT: 3/10/2024
I was on an f4xxx board, but I used the following SPI/GPIOs for the SD/Display: SD: SCK -> PB10 MISO -> PC2 MOSI -> PC1 CS -> PC3 DISPLAY: SD0 (MISO) -> n/a (specify master only transmit in .ioc) LED -> +3.3V SCK -> PA5 SDI (MOSI) -> PA7 DC -> PB1 RESET -> PB0 CS -> PA4 VCC -> +5V
I uploaded my wyatt.c and wyatt.h code, but it doesn't look like main.c is configured for FreeRTOS to run. Once it is, ADD THE FOLLOWING CODE AS ITS OWN THREAD:
HOW THE FSM WORKS: The display initializes by showing the names of the files on the SD card, and blinking to show which file is currently hovered over. Change boolean variables "sel_next" and "sel_prev" to highlight files other than the one currently highlighted. change boolean variable "readFile" to open the file that's currently hovered over and access its contents. change boolean variable "viewDirectory" to close the file you're reading and view the list of file names again.
changing "readFile" while already reading a file does nothing. changing "viewDirectory" while already viewing the directory does nothing.
END OF NOTES BY WYATT.

UCSIG/attiny85_time_switch
Low-power time switch using the ATtiny85 microcontroller.
It measures 30 × 100 mm and has 2 copper layers, 1.6 mm thick.
46 parts, built around the MIC5504-3.3YM5, CL21A106KOQNNNE, MBR0530 and CR0805-JW-102ELF. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the jkmunson/RTOS_POD repository on GitHub, at the commit this page was made from: the board is BatteryCharger/462FinalProject.kicad_pcb and its schematic BatteryCharger/462FinalProject.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask jkmunson before reusing the design.
