Questions
- You are visualizing something and you are pretty sure there is some UART traffic on your scope. You see the following waveform. What is the baud rate?
Figure 6.24 – UART oscilloscope signal: what is the baudrate?
- What is QSPI?
- What is the usage of the parity byte in UART?
- Who invented the I2C protocol?
- How can you use multiple 24LC EEPROMs on the same I2C bus?
- You have to man in the middle an I2C bus with two different devices and a master. Sadly, the hardware peripheral on the blue pill can only have a single address and you can't think of a way to have it alternate between the addresses (the master apparently talks randomly to the devices). What would be your approach?
