The firmware training board was designed as a part of the fall 2021 firmware bootcamp re-design led byGordon Fountain (Deactivated). The primary activity in the new firmware bootcamp is to have students write firmware code to read the input of a potentiometer through an MCP3004 Analog analog-to-Digital converterdigital converter using serial peripheral interface (SPI). Once students have written their code, they will use the physical firmware training board to test.
NOTE: The board was initally designed for an SMD version of the MCP3004, however due to lack of chip avaliability, modifications were made to accomidate a THT chip.
