Overview[edit]
I'll clarify something. I'm running 5 UARTs. Because the 8051 only has one hardware UART, I have to make 4 software UARTs. If I use an interrupt for the hardware UART then when it runs then the software UARTs will be out of sync – Mike Jun 18 '18 at 19:42. Serial communication using UART or USART of a microcontroller 8051 AVR PIC, software implementation of half-duplex UART and MAX232 interfacing with microcontrollers 8051 AVR PIC. It contains a source code editor, software debugger, assembler, cross compiler, simulator. It supports Embedded C and assembly programming for different microcontrollers such as 8051, ARM. On successful compilation of software, KEIL generates a HEX file that can be flashed to 8051 microcontrollers. The 8051 C-Compiler uC51 is well known for it's high quality and high density code. You can develop high quality software for any 8051 in ANSI C. ΜC/51 comes with an. UART Example for PIC16F887 CCS C code: The code used in this example is shown below. The function #use rs232(UART1, baud = 9600) is used to configure the UART protocol. Here the hardware UART module is used. If the pins TX and RX (RC6 and RC7) are used by an other application we can use software UART.
The C8051 is a ‘hard wired’ implementation of the 8051 microcontroller CPU, as opposed to the original micro-coded version. The instruction set is mapped to a basic two-stage pipeline to increase throughput while maintaining an 8-bit program memory width. The result is a high-performance 8051 microcontroller architecture that executes most instructions within 1 or 2 clock cycles and delivers 20 to 25 times the performance of the original 8051 core.[1]
Families[edit]
Analog Intensive[edit]
ADC resolutions range from 10 to 24 bits, and other on-chip analog peripherals include DACs (resolutions to 12-bits), a voltage reference, comparators, a temperature sensor, programmable gain array (PGA) and oscillators.

ToolStick[edit]
The Silicon Labs ToolStick is a development system that allows designers to develop and debug application firmware directly on the target microcontroller using the Silicon Labs Integrated Development Environment (IDE). Once complete, designers can replace the Daughter Card with a Programming Adapter and program blank devices for use in their actual system.[10]
Silicon Labs IDE[edit]
Swayamvaram serial last episode in malayalam full. The Silicon Labs Integrated Development Environment (IDE) is a complete, stand-alone software program that includes a project manager, source editor, source-level debugger and other utilities. The IDE interfaces to third party development tool chains to provide system designers a complete embedded software development environment. The IDE supports the entire 8-bit microcontroller (MCU) portfolio.
Keil® PK51 Developer’s Kit[edit]
The Keil PK51 Developer’s Kit includes an industry-leading 8051 C compiler, linker and assembler for use with Silicon Labs’ 8-bit microcontrollers and Studio. This toolchain package provides the build support for 8051 projects, while the IDE provides editing and debugging support. This free toolchain comes without a time or code size limit.[10]
Other tools and utilities[edit]

The Flash Programming Utilities allow designers to download code to a device and perform other memory operations without needing to use the Silicon Labs IDE. These utilities are static examples of the C8051Fxxx On-Chip Interface Utilities DLL detailed in application note AN117. The downloaded installation utility installs both the Windows Flash Programming Utility and the Command-line (32-bit) Flash Programming Utility.[10]
Debug Driver for Keil µVision Software
The µVision debug driver allows the Keil µVision IDE to communicate with Silicon Labs on-chip debug logic. In-system Flash memory programming integrated into the driver allows you to rapidly update target code. The µVision IDE can be used to start and stop program execution, set breakpoints, check variables, inspect and modify memory contents and single-step through programs running on your actual target hardware.[10]
Free Development tools[edit]
The C8051 is also supported by FOSS tools.
Small Device C Compiler[edit]
The Small Device C Compiler is an optimizing standard (ANSI C89, ISO C90, ISO C99, ISO C11) C compiler. It supports the C8051 via the mcs51 backend.

PAULMON is a user-friendly 8051 family monitor, intended for usein a single board computer like the development board below. Byplacing PAULMON in the board's EPROM, the board will 'boot-up' toa friendly menu-driven monitor which allows you to download yourprograms to RAM and run them, which is much faster and easierthan reprogramming the EPROM. PAULMON also provides several featuresto help you debug your programs, including adisassembler and single-step program execution. It is veryeasy to use and together with an 8051 family assembler, such asthe one above, it provides a very low-cost 8051 developmentsystem.PAULMON is in the public domain. You may use piecesof the code in your own programs and even incorporate the codeinto your own commercial products, if you wish. Download PAULMON2 Source or Object Code.Nearly everything is improved andseveral new features have been added.. generally much betterthan version 1, even in the beta versions.Documentation for PAULMON2 isavailable on-line. PAULMON1 was originally developed in the Fall of 1991 in aboutfour weeks. The code has remained fixed, but my own needs havechanged from project to project over the years. These changes,additional features, plus a major overhaul of the existing codeis finally available asPAULMON2.

Atmel 89C2051 in-circuit programmerTheAtmel 89C2051is a 20 pin version of the popular 8051 microcontroller.It's got only 2k of built-in program memory, but it's Flash ROM, so youcan easily reprogram the chip without the UV erasure step. This reallycool Atmel version has all of the normal 128 bytes of ram (unlike someother low-cost 20 pin 8051 family members) and they even left the built-inUART built-in. It's got some other features, but best of all, it costsonly about $5(US) from Marshall in single piece quantities.Please keep in mind that neither I nor Oregon State Universityrepresent Atmel or Marshall.I have designed and built a simple programmer for this cool partwhich can reprogram it in-circuit. You place the 89C2051in this board, and connect the board to your project's 20 pinsocket with a ribbon cable. You can download code to the programmer,reprogram the Atmel chip, and then place the chip back into thecircuit. Since it's Flash ROM, no UV erase step is required. Youcan reprogram and test your code without moving the chip betweensockets. As well, the programmer supports an 'echo-thru' mode, wherethe 89C2051's UART output is echoed to the terminal controlling the89C2051 in-circuit programmer, but only while the 89C2051 is runningin-circuit. To get started now, the design is quite similar to thedevelopment board example above, with the addition of the followingchips: 74HC00, CD4007, and four CD4066. The three unused ANDgates in that example are used here. Two NPN and one PNP small-signaltransistors are needed, as well as a 12 volt power supplyfor the programming voltage and 4000 series logic.Only one of the 82C55's is used, but one 82C55 is required.BETA Version 0.004 is now available, alsoin ZIP format.As well, BETA Version 0.003 is still available,but 0.004 is much easier to use. Someday more reasonable documentation and a schematic of therequired hardware will appear. For now, thisbeta release schematic is availablefor those who want to try to add the hardware support to anexisting development board. Other Resources |
