Simple 78K/V850/LPC programmer

Works of FatFS author chaN teacher

Overview

In early 2005, NEC Electronics launched small-pin-count microcontrollers such as PIC/AVR based on the 78K0S architecture. The 78K architecture has a register set similar to the i8085 and additional bit manipulation instructions. It is said to be a classic architecture, but the memory organization is simpler than PIC/AVR. There are various devices with dedicated peripherals, and the 78K series occupies a considerable share of industrial equipment. In the early days, only OTP/Mask products were available, so they were not popular among electronic crafts. However, the small pin count 78K series with flash memory is getting some attention from Japanese microcontroller geeks. Powerful IDEs (compilers, assemblers, simulators, etc.) are also provided for free. I built a very simple 78K0S flash programming adapter for these devices. In addition, the author built a universal programming adapter for V850ES, LPCxxxx, STM32F, etc.

CD4013 two-way frequency division circuit
[color=#333333][font="][size=14px]I want to use CD4013 to build a two-way frequency divider. Since there is no CD4013 in Pspice, I used CD4013B. However, it cannot be divided into two directions in th
Timer 1 is used as a serial port baud rate generator, with a simple source program
I am currently using timer 1 to experiment with the AT89C51 serial port baud rate generator. The program is as follows: #include#define uchar unsigned char #define uint unsigned int uchar g_ucReceived

Question 1: Can anyone recommend a free jvm for wince? I googled but couldn't find any free ones. Question 2: How does wince support jsp? I found that wince only supports asp. Question 3: Is there a s
Post some pictures of the plane!
Today I accidentally saw the photos I had saved on my computer. It was a Russian plane. It was hit so badly but still made an emergency landing. The quality is indeed better than the domestic craftsma
