This article takes MSP430f149 as an example and introduces in detail its commonly used P1, P2, P3, P4, P5, and P6 ports. There are no special input/output instructions in the MSP430 system, and input/...
I developed a signature program using VS2003, but when I wanted to save the Bitmap generated by the signature, I encountered this problem! I hope an expert can help me solve it....
I received the gift, opened it and saw...raincoat?????
Unzip it, unfold it, oh, it turns out to be... It turns out to be...Bags!!
The gifts from EEWORLD are so creative. Thank you....
The hardware is the same, and even the board is not powered off. It is just re-simulated with different optimizations. When using IAR high optimization, the SCK of SPI1 has no waveform: When highly op...
In the previous post, I used GCC to compile a piece of code to operate the GPIO of the E203 SOC, and then used the openocd debugging tool to write the binary directly into the ITCM memory of the E203,...
Today's portable medical devices allow patients to diagnose and treat themselves, move around freely, and even use the devices when they are out and about. To achieve the "easy to carry" feature, po...[Details]
In today's society, heart disease has seriously affected people's life safety. Many patients with sudden heart attacks are threatened because they cannot get timely treatment. Traditional ECG monito...[Details]
Human body information monitoring is an emerging field. People envision developing wireless electroencephalogram (EEG) monitoring equipment to diagnose epilepsy patients. Wearable wireless EEG can ...[Details]
Currently, it is impossible to dynamically obtain patient information in medical monitoring. Once the patient's condition worsens, emergency treatment cannot be implemented in the first place, and the...[Details]
Obtaining real-time and reliable traffic information has always been a bottleneck problem in the development of intelligent transportation systems. The establishment of an intelligent transportatio...[Details]
As the whole equipment is becoming increasingly miniaturized and power-saving, low-dropout linear regulators (LDOs) with low power consumption are becoming the mainstream in the market for linear regu...[Details]
Due to the needs of medical development, in many cases, general thermometers can no longer meet the requirements of fast and accurate temperature measurement, such as measuring human body temperature ...[Details]
