Design Tips
Question 1:
Answer 1:
The most common reasons are
1.
2.
3.
You are using the high speed mode (BRGH is set) on one of the devices which has an
errata for this mode (PIC16C65/65A/73/73A/74/74A).
You have incorrectly calculated the value to load in to the SPBRG register
The sum of the baud errors for the transmitter and receiver is too high.
Using the Asynchronous mode I am getting a lot of transmission errors.
