EE Evaluation Intelligence Bureau reports for you! Here are the latest evaluation activities and the evaluation reports that were just released in the past week. If you have evaluation opinions or fre...
Dear experts: I am a rookie~~~I have a question to ask: My question is as follows: An input voltage of -10V~+10V, with an accuracy of 0.01V, when the input is -0.05V to +0.05V (this voltage is adjusta...
As shown in the figure above, after the input voltage is divided, it enters the OP common-phase terminal. The given resistance value is multiplied by the sampled current value I and subtracted from th...

[color=#000] You need a voltage reference, but you’re not sure how to choose the best one for your application. Then you’ve come to the right place! In this blog post, I’ll discuss some key voltage re...
International Solar Photovoltaic Network News: Chinese inverter company Sungrow announced that it will build a 3GW photovoltaic inverter manufacturing plant in Bangalore, the capital of Karnataka, ...[Details]
CMSIS Driver has similar API functions and similar calling methods. It is a further encapsulation based on the ST HAL library. It is much more convenient and simpler to use and configure than the ST ...[Details]
After searching a lot of information, I finally understood the time base timer. I did not use any library functions but operated the registers directly. The following introduces the systick in STM32...[Details]
Because the STM32 HAL library only has millisecond-level delay for HAl_Delay(), in order to achieve accurate microsecond-level delay, Systick has to be modified. However, since it is used internally ...[Details]
introduction STM32 has many registers, which are difficult to remember, so the official packaged two sets of library functions. One is the standard library, but the official has not updated it on F7,...[Details]
Development Background: 1. Main chip - STM32F207VCT6; 2. TCP/IP protocol stack - LWIP, transplanted based on ST routines; 3. Operating system - none (bare metal); Anomalies: 1. Power on the device wi...[Details]
Since the second half of 2017,
the market share of
quantum dot
displays has dropped significantly, with global sales falling from 3.42 million in 2016 to 2 million in 2017, a 42% decrease; d...[Details]
From last year to now, competition in the photovoltaic inverter industry has become increasingly fierce. In addition to the introduction of new products, various marketing and promotion methods hav...[Details]
With the implementation of the first version of the NR sub-6GHz draft of 3GPP in December 2017, and the subsequent Phase 2 drafts, semiconductor manufacturers and terminal manufacturers began to ...[Details]
Since China began to try to produce panels independently in 1998, in 2018, China's panel industry has gradually upgraded from a marginal industry to the largest production scale. Especially in the ...[Details]
I rewrote the main part of this program. The program uses the watchdog as a normal timer and scans the digital tubes in the watchdog interrupt. In addition, I added a display buffer. If you want to d...[Details]
The ARM11 (S3C6410) processor is selected as the hardware platform, the embedded Linux operating system is used as the software platform, the background difference method and the frame difference...[Details]
In 2018, the National Development and Reform Commission issued a new photovoltaic subsidy policy. The benchmark on-grid electricity price was significantly reduced, the return on investment decreased,...[Details]
