The CC3235S and CC3235SF SimpleLink Wi-Fi devices support 5 GHz and 2.4 GHz and can coexist with Bluetooth Low Energy/2.4 GHz. Although security is one of the biggest challenges in wireless communicat...
There is a small problem in reading, and one more character will be read at the end. This is because the stop and NACK must be sent before receiving the last data, and I put this sending in the interr...
A flag to another clock domainIf the signal that needs to cross the clock domains is just a pulse (i.e. it lasts just one clock cycle), we call it a "flag". The previous design usually doesn't work (t...
