8051 Programming Using Keil UVision IDE: In this short Instructable we will learn How to setup the Keil uvision IDE,Compile a C program and generate hex code for the 8051/8052 architecture.You can find the original article on 8051 programming using Keil uVision IDE here.

• Download keil uvision 4 windows 10 64 bit for free. Development Tools downloads - uVision by KEIL and many more programs are available for instant and free download.
• Keil µVision 5.32.0 can be downloaded from our software library for free. The file size of the latest installation package available is 59.8 MB. Keil µVision was developed to work on Windows XP, Windows Vista, Windows 7, Windows 8 or Windows 10 and is compatible with 32-bit systems. The software relates to Development Tools.

Select Project - New microVision Project.

Save new project in chosen folder. It will have the extension .uvproj.

Select the target vendor and device from pull down list. (STMicroelectronics STM32F107VC shown)

Normally select Yes to option 'copy Startup Code to Project Folder'. At RMIT for the first laboratories a simplified STM Startup Code is provided so select No for this option.

Note: If the start up file needs to be added at a later date it is file: Microcontroller Board Start up code STM32F407VG Discovery ..KeilARMStartupSTSTM32F4xxstartup_stm32f4xx.s STM32F429ZI iDiscovery ..KeilARMStartupSTSTM32F4xxstartup_stm32f429x.s STM32F107VC Keil MCBSTM32C ..KeilARMStartupSTSTM32F10xstartup_stm32f10x_cl.s LPC1768 MBED ..KeilARMStartupNXPLPC17xxstartup_LPC17xx.s

Create a new C or assembly file (ie *.c or *.s) and save.

Assembly Language Example The following is an example of the minimum code in assembly language. This code also includes the minimum start up code.

AREA RESET, DATA, READONLY EXPORT __Vectors __Vectors DCD 0 ;program does not require a stack DCD Reset_Handler AREA |.text|, CODE, READONLY EXPORT Reset_Handler Reset_Handler PROC Loop b Loop ENDP END

Notes: In the example the code is separated into two areas, the RESET and the |.text| or DATA and CODE. The program in the RESET area will be placed at location zero while that in the CODE area will be placed in flash memory which starts at location 0x08000000. On reset the ARM microcontroller expects the initial value of the stack pointer to be placed at location 0 and the location of the Reset_Handler code at location 4. The Keil development tools expect the labels _Vectors and Reset_handler so these must be included and made available to the tools using the pseudo instruction EXPORT. The above code includes minimum start up code.

C code example:The following is an example of the minimum C program when the start up code has been included.

#include <stm32f10x_cl.h> //See notes below void SystemInit() { //routine called by later versions of start up code //leave empty or add initialisation code as you wish } int main (void) { while (1) { } }

Notes; The start up code will Call the routine SystemInit: If initialisation code is placed in this function then if the debugger option 'run to main' is chosen this function will be executed on starting the debugger. Otherwise the debugger will only run to the first line of code in the startup program. Branch/Jump to the 'main' function. Note there is no return address to the start up code so the above program must run forever ie while(1). The first line includes a header file with definitions of all the ARM ports, registers etc. Device LPC1768 STM32F107 STM32F407 STM32F429 Target Board MBED Keil MCBSTM32C Discovery iDiscovery Header File LPC17xx.h stm32f10x_cl.h stm32f4xx.h stm32f4xx.h

Keil Microvision 4 For Windows 10

In Project window expand Target1 and right click on Source Group 1 . If selected earlier the start up code should be already present. Select Add files to Group Source Group 1. Add files as required. the Add button will not acknowledge the operation but performing the Add twice with the same file will give the message that the file is already a member. Close when complete.
