I want to learn Windows CE development. I used to learn C++ but never C#. I often use VS2005. I want to ask if I need to learn C# to develop Windows CE with VS2005? Are there any good textbooks for le...
[i=s]This post was last edited by Zeng in on 2015-2-11 15:19[/i]I used 430's SPI routine to modify and drive the SPI color screen, but the screen refresh is too slow.The routine uses LFXTCLK as the cl...
Recently, there is a project that needs to increase DC5V to DC18V. I thought about using MC34063 before, but MC34063 has low efficiency and large ripple, so I gave up. Now I want to use SY7208, but fe...
1. Problem When developing STM32 with IAR, I found that I could not print floating point numbers by redirecting printf to the serial port. The code is as follows: The output is as follows: It can...[Details]
In the actual project development process, it is common to encounter modifications to the hardware circuit, and then the modified part requires the modification of the driver. Thinking about the comi...[Details]
Regarding the PHY construction of LWIP, the PHY chip used is LAN8720A, RMII mode. Regarding the hardware connection part, the Atomic board F407 is used, and the hardware connection is as follows: ...[Details]
The last two blogs talked about a version problem of STM32CubeMX and the problem of hardware reset. When you solve these two problems, you will find that after the program is burned into the board, t...[Details]
After studying the F4 FSMC method to drive the touch screen for a few days, I have gained some understanding, which are listed below. The unorganized record is only for my own reference in the future...[Details]
1. Initial understanding of FSMC: FSMC consists of 4 modules: (1) AHB interface (including FSMC configuration register) (2) NOR flash memory and PSRAM controller (when driving LCD, LCD is like a PSRA...[Details]
Automotive LCD Instrument Clock EMI Solution As early as 2014, the market size of China's automotive full LCD instrument has reached 3.506 billion yuan, and it is expected that by 2020, this s...[Details]
What is SYSTICK: This is a 24-bit system tick timer, SysTick, with automatic reload and overflow interrupt functions. All microcontrollers based on the Cortex_M3 processor can obtain a certain time ...[Details]
This paper proposes a design scheme for an embedded CNC system based on ARM and FPGA. The software and hardware design of the ARM system, the implementation method of hardware fine interpolation ...[Details]
Independent watchdog (IWDG) and low power mode are often used in STM32 development. The watchdog is to detect and solve faults caused by software errors, and the low power mode is to enter sleep mode...[Details]
1) Independent watchdog has no interrupt, window watchdog has interrupt 2) Independent watchdogs can be divided into hardware and software, while window watchdogs can only be controlled by software...[Details]
OSC_IN and OSC_OUT are external crystal pins by default. If you do not use an external crystal oscillator on the STM32, how to connect OSC_IN and OSC_OUT If you use the internal RC oscillator instead...[Details]
Today I am using the AD function of the stm8s microcontroller. There are ten channels from AN0 to AN9 on the microcontroller. I want to use only three of them, AN5 to AN7. //ADC initialization void A...[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]
1. SCL is always controlled by the Master. SDA is controlled by the Slave when reading data and by the Master when writing data according to the direction of data transmission. After the 8-bit data i...[Details]
