I'm debugging the IIC communication of C2000 recently, but it seems to be very troublesome. I found examples of 51 and STM32, but they are not right after transplanting. It's a headache. Which great g...
My graduation project is to make a TV signal transmitter, but I have never drawn a radio frequency circuit board and I don’t know how to draw one, so I would like to ask the masters for help. I would ...
I am using a Huaheng AT91ARM9200 board and have a problem testing flash read and write. After modifying /devices/mtd/maps/at91arm9200 and adding a new partition, the open is successful and the first c...
The company has initially decided to develop a "distance measurement and locator based on DWM1000". The requirements are as follows: 1. In the case of line of sight (open, no obstacles), achieve dista...
1. Test conditions Hardware: STM32L432KC Main frequency: 80MHz Compiler: IAR 8.20.1 Compiler options: High Speed no size constraints CRC generator polynomial: 0x782f 2. Test Method The softwar...[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]
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]
The application of millimeter wave technology in mobile communications also involves a series of technical problems, including the large propagation loss of millimeter waves and the susceptibility ...[Details]
In 1949, after three years of civil war, the Nationalist government was defeated and retreated to Taiwan. The political and academic circles launched a large-scale reflection on why they failed in ...[Details]
Household photovoltaic power stations mainly utilize idle resources on existing household buildings, such as roofs, wall facades, balconies, courtyards, etc., to install and use distributed photovo...[Details]
As shown in the figure, the author soldered a STM32F207VET6 board using a TQFP (32-100PIN) 0.55MM to direct plug adapter board. The board leads out the SWD debug interface (only PA13 and PA14 are occ...[Details]
1. Function and purpose There are two pins BOOT0 and BOOT1 on each STM32 chip. The level status of these two pins when the chip is reset determines which area the program starts from after th...[Details]
Note: This STM32 microcontroller is the STM32F103 series. The ADC of Stm32 has DMA function. This is beyond doubt and is what we use most! However, if we want to sample a signal (such as a pulse sign...[Details]
The code for using timer 0 to implement a running light in a 51 MCU is as follows. The LED light is connected to port P1. The code is annotated below, so I won't explain it in detail. My English is n...[Details]
Single-chip microcomputer experiment design: It is required to use 8951 series single-chip microcomputer, design a pulse generator with a pulse width duty cycle of 50%, 25% adjustable, and a period o...[Details]
Assume that the MCS-51 microcontroller uses a 12MHz crystal oscillator, and wants to use a timer to generate a pulse with a duty cycle of about 30% and a period of 60ms at port P1.0. ;==============...[Details]
