For MSP430, DCO is a major feature of 430. We can obtain a relatively accurate high-frequency clock source through DCO without any crystal oscillator. For example, the low-cost G2 series can obtain a ...
I have a few questions about the heap: 1. There is an algorithm in my program that uses a 5M global variable, which is so large that my thread cannot start. Now I want to change it to dynamic allocati...
I want to implement a camera preview rotation 90 degrees function on the pxa310 platform under wince6.0. However, the format is yv12, so I add a transform filter between the source filter and the rend...
Awards have been awardedI always remember that the forum engineers complained that the code generated by stm32cubemx was terrible. I always thought that this kind of graphical configuration software w...
I wonder how you deal with the IAP program upgrade problem and what is the basic method?My personal idea is to refer to the methods of u-boot and linux. I wonder if there is a better implementation pr...
Microchip's PIC18F46J50 is a low-power, high-performance 8-bit USB microcontroller (MCU) using nanoWatt XLP technology. The current in deep sleep mode can be as low as 13nA, the operating voltage i...[Details]
