SCK, MISO, and MOSI are automaticly assigned by the SPI enabled in the .ioc ^ but CS, RESET, and DC need to be assigned manually. The ili9341.h file and main.h file will need to reflect the .ioc file pin assignments. I used stack size = 512 for the display/SD thread. Testing lower values has caused a fault in the past. Will need to change the "startup file" from f4xxxx to whichever…

462FinalProject design files

The KiCad project lives in the jkmunson/RTOS_POD repository on GitHub; these links point at the commit this page was built from.

462FinalProject: common questions

What microcontroller does the 462FinalProject use?

The 462FinalProject is built around the STM32G030F6Px, from the STM32 family.

How big is the 462FinalProject PCB?

The 462FinalProject measures 30 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the 462FinalProject?

46 components, from 22 distinct parts. The full bill of materials is listed on this page.

Where can I download the 462FinalProject design files?

From the jkmunson/RTOS_POD repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the 462FinalProject design in my own project?

The repository has no license, so all rights stay with jkmunson. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the 462FinalProject without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
