Procedure 30 for finding an MSP430

According to the incoming interruption time, it is OK to refresh the digital tube.

The MSP430 is programmed and compiled with IAR Embedded Workbench software**.

MSP430 microcontroller is called mixed-signal processor, because it integrates multiple analog circuits, digital circuit modules and microprocessors with different functions on a single chip according to practical application requirements to provide a "single-chip microcomputer" solution. This series of single-chip microcomputers are mostly used in portable instrumentation that requires battery power.

MSP430 microcontrollers are generally programmed and compiled with IAR Embedded Workbench software.

Of course, the programming of single-chip microcomputer can also be written with other software.

Dear, we are glad to answer the MSP430 microcontroller parameters are as follows: MSP430 series MCU is a 16-bit ultra-low power with reduced instruction set (RISC) mixed signal processor (Mixed Signal Processor) that Texas Instruments (TI) began to introduce to the market shed dust yard in 1996. MSP430 series microcontroller is a 16-bit microcontroller with reduced instruction set (RISC) structure, rich addressing methods (7 source operand addressing, 4 destination operand addressing), concise 27 kernel instructions and a large number of analog instructions; A large number of registers as well as on-chip data memory can participate in a variety of calculations; There are also efficient lookup and processing commands.

These features ensure that efficient source programs can be programmed. Fast computing speed: MSP430 series microcontrollers can achieve 40ns instruction cycle driven by a 25MHz crystal. The combination of a 16-bit data width, a 40ns instruction cycle, and a versatile hardware multiplier (capable of multiplying and adding) enables certain algorithms for digital signal processing (e.g., FFT, etc.).

The reason why the ultra-low power consumption MSP430 microcontroller has ultra-low power consumption is that it has its own unique features in reducing the power supply voltage of the Minjia chip and flexible and controllable operation chain Nazen walking clock. First of all, the power supply voltage of the MSP430 series microcontroller is voltage. As a result, the chip can operate at a clock of 1MHz with a minimum current of around 165 A and a minimum power consumption in RAM hold mode.

There are many reasons that cannot be listed one by one.

2. I didn't choose the chip model.

4. The operating system version does not support the software you use.

Hardware problems: 1. The firmware version of your program does not match the chip on your target board (maybe the firmware version is too high or too low, you check whether the firmware has been upgraded recently).

2. The MSP430 chip on your target board is broken.

6. The crystal oscillator on your target board is broken.

7. The ripple of the power supply of your target board is too large, and the capacitor on the power supply side may be broken.

Is the cable of the <> burner right? Make sure the burner is good, and you can burn it in if there is no problem.
