1 month project, undergraduate level |
Be able to receive UART data from SCuM even when clock calibration isn’t perfect.
groundwork
create a repository for your source code at https://github.com/orgs/PisterLab/teams
Take 2x nRF52840-DK boards, connect GND and 2 pins for UART TX/RX
program the board so one sends bytes to the second
play with the BAUDRATE
register, make sure you can change the baudrate
use a scope to make sure the timing makes sense
feasibility
change the the BAUDRATE
register to values not listed in the “approved” list in the Product Specification
check whether timing makes sense with a scope
check UART still work
the goal is that you can change the baudrate for the UART to any baurate you can
if this doesn’t work, project stops here
learning baudrate
set pins as GPIOs
use a clock to sample transition times
calculate baudrate
set pins as UART
receive bytes!
