Differences between various MSP430 Launchpad emulators [Copy link]

 

When I was learning 430, the so-called classic entry-level 149/169 development boards cost hundreds of dollars, and even pirated emulators cost more than 200 yuan. The traditional official evaluation board was so noble that ordinary people could not touch it. This was a high threshold for learning MSP430. The launch of TI's MSP430 launchpad is definitely a benefit for students learning MSP430. The onboard emulator can be played by connecting a USB cable. In the past few years, from the first G2 to the current G2ET, more than ten models have been launched in the 430 series alone. As the saying goes, people strive for higher goals, and the boards are getting higher and higher. The onboard emulator has evolved from the initial G2's eZ430 emulator to the current G2ET, which is already eZ-FET v2.0. There are 4 main versions:

• eZ430
• eZ-FET lite
• eZ-FET v1.x
• eZ-FET v2

Functions are enhanced from top to bottom

The judgment is as shown in the figure:

eZ430: MSP430F1612 + TUSB3410

eZ-FET lite: MSP430F5528 only

eZ-FET: MSP430F5528 + MSP430G2452

Differences:

External power supply

eZ430: 3.6V

eZ-FET/eZ-FET lite: 3.3V

Supported Platforms

eZ430: Windows only

eZ-FET/eZ-FET lite: windows/linux/OSX

EnergyTrace Technology

eZ430/eZ-FET lite: Not supported

eZ-FET: Supports EnergyTrace/EnergyTrace++ (EnergyTrace++ also requires target device support)

EnergyTrace is a tool for measuring the power consumption of target devices, which is very helpful for low-power application development, as shown in the figure:

Supported target devices

eZ-FET/eZ-FET lite: Supports all SBW interface devices

eZ430: The documentation does not indicate that all SBW devices are supported, but I can use the G2 simulator to simulate 5529, so at least most or even all of them are supported.

Simulator production

TI's simulator software and hardware are open to the public: http://www.ti.com/tool/MSPDS

For eZ-FET lite, TI provides a more complete production solution and binary firmware: http://software-dl.ti.com/msp430/msp430_public_sw/mcu/msp430/MSP430_ezFETLite/latest/index_FDS.html

I learned something, thumbs up!

The launchpad emulator part of ti is really a big shot against a mosquito. When I got the G2 board a few years ago, you can see the large area of emulators and the TUSB3410. It seems that there is no cost. However, it is really good to buy a board for 50 yuan and emulate 5438.

Later, the 5529 board refreshed my understanding. What is the 2553 in the simulator area used for? Is there a CNC DCDC? The big analog manufacturers are just so impressive.

But now TI really is, alas, not keeping up with the pace of the ARM era

TI's MCU is a self-contained system with impeccable hardware, but it has relatively little support in terms of open source, and its software ecosystem seems to have not been established.

The problem is that TI's products are upgraded and eliminated too quickly. TI's ARM has never had a status, which is very embarrassing. The company has C2000 and MSP430, which are very distinctive MCUs. The general MCU has no characteristics and competitiveness, so it is estimated that they have given up. The MSP432 that is currently being promoted has never supported mbed and is unique.

It is true that Launchpad is a self-contained system. It is definitely not as powerful as Arduino in terms of ecosystem. Except for TI, other manufacturers are basically compatible with Arduino interfaces. However, a powerful manufacturer must have its own characteristics.

In terms of software, CCS is now free, and GCC is getting better and better supported, and is also making progress bit by bit.

Almost everyone who has used the 5529 Launchpad will encounter firmware bugs, which is the worst experience . In comparison, the 2553 and 5969 ones are quite stable.

Model: MSP430FR6972, please recommend a development board, thank you.

Thank you for sharing, but can you also share your learning experience, such as a detailed example, thank you

There is no ready-made development board for the model you mentioned. It should be similar to learn with FR6989.

I am not a big shot, I just learned early, but I am still a rookie. In the days to come, I will learn and share.

The captain has done a very detailed study.

Uncle free is a real master, learn from you!

Are you talking about the official firmware or the emulator one?

There is still a market for 430. I saw a German sensor manufacturer using the amplifier built into 430.

Although I jumped from 51 to 430 and have deep feelings for 430, but at the price of 430, when encountering low-power products, wouldn't it be better to stick a 20-pin STM8L051? A company I interviewed a few years ago still used 5438 to make digital walkie-talkies, and it is estimated that they have switched to ST in recent years. The advantages of C2000 are getting smaller and smaller.

I personally think that TI's unique style fits the tough folk customs of Texas. XD

TI's products have no cost-effectiveness. Those who have cost requirements should definitely not choose them. I just play around with them as a hobby and never consider cost-effectiveness. I just play with whichever one I am familiar with and comfortable to use. Haha

LZ is very careful and I admire people who make summaries and generalizations.

Thanks for sharing. TI's products are really good. "TI's simulator software and hardware are open to the public" is really good and can reduce the development time of new projects.

The captain is a 430-level boss, a veteran, and an awesome guy.
