C883298_4-bit common cathode LED digital tube driver chip solution verification board

Overview

AiP650 is an LED driver circuit with a keyboard scanning circuit interface, mainly used to drive digital tubes. This solution verification board is designed to drive an 8-segment 4-bit common cathode digital tube. It also leads to 8-way buttons to verify its button scanning and LED driving functions.

V1.0 problem found:

1. The K17 button network is not connected. Since the EDA software did not report an error, it was not discovered during the design.

Later replenishment will fix this problem. The first batch of 200PCS is produced as a gift. If you use KI7, please solder the jumper first.

(After we actually inspected the first batch of production materials, we found that this area was connected during actual production, but we cannot rule out that some individuals were not connected)

Ask about MSP430f149 timing problem
Using MSP430f149, the problem is, for example, set Mclk to 8M, smclk=mclk, timer A also uses smclk, if the timing is 1s, CCR0=8000, (CCR0=1s/(1/800M)); I can't figure out how to accurately time, I don
