1. Watchdog timeout reset

The watchdog overflow reset is caused by not feeding the watchdog in time or not turning off the watchdog at the beginning of the program. The watchdog should be shielded during the debugging phase and the watchdog should be turned off using the WDTCTL = WDTPW + WDTHOLD; statement at the beginning of the program.

2. Stack overflow reset

If the stack overflow causes a reset, you should be glad that you found it. After the program is compiled, you should look at the map to check the current stack usage. The 22×2 stack of 430 and 2471 are both 80B by default, and you can turn on the stack usage alarm. According to the old bird, you should know how much stack you have used. For novices like us, I say that the compiler knows, haha.

3. Reset caused by insufficient voltage and other problems

Since the USB debug of 430 can provide power, sometimes the target board will forget to connect to the power supply. When the program runs to certain places and turns on certain devices, the debug power supply is insufficient, which will cause a reset. The way to avoid forgetting is to change the burning interface to Target power supply for boards with high current.

RGB LED mood lighting - MSP430 creates warm lighting

High brightness LEDs are increasingly being used in lighting applications. Here we present a simple "mood light" using only a few components. All three LEDs are powered by a constant current using a switching regulator, while brightness control is done by an MSP430 microcontroller that generates three PWM signals. T

The taste of bitterness before sweetness is all in the making of MSP430UIF emulator

Some time ago, I used my spare time to make an MSP430 USB emulator . I took a lot of detours along the way, so I wrote down the relevant process for future reference: 1. First, solder TPS77301 and its peripherals. TPS77301 is a voltage regulator chip from TI. The output voltage used in the emulator is 3.6V, which is m

The Development and Characteristics of MSP430 MCU

　　The development of MSP430 microcontroller 　　From 1996 to early 2000, Texas Instruments launched several series, including 31x, 32x, and 33x. These series have LCD driver modules, which are more conducive to improving the integration of the system. Each series has ROM type (C), OTP type (P), and EPROM type (E) chips.
