Keil's Microcontroller Development Kit (MDK ARM) software package integrates the C/C++ ARM RealView compiler and the Keil uVision integrated development environment. Using the ARM MDK simplifies the design cycle and reduces development time.


This product provides the developer with a rich development environment optimized for a wide range of ARM-based MCUs (ARM7, ARM9 and Cortex M3) from manufacturers such as Analog Devices, Atmel, Freescale, Luminary, OKI, NXP, Samsung, Sharp, STMicroelectronics and TI and more.
Support for these processors must be installed in the package manager (Project->Manage->Pack Installer) by installing packages
1. or through it from the Internet
2. either by downloading files from distributions ( this distribution or this one for a newer legacy ) or downloading files from the old site on the Internet (from it you can also see a detailed list of currently supported devices) and installing the downloaded packages in the same package manager, but already from it yourself downloaded files
How to install the MDK - see the recommendations in the KeilMDK538.txt file in the distribution
How to update Keil instructions are not needed - the installer will automatically update the already installed Keil MDK. In the case of an update, you do not need to treat anything (you should pick up your existing license)
It will not be superfluous to get acquainted with what has already been posted on the tracker for Keil MDK HERE .

Cale's installer no longer includes the fifth compiler for armes. If you need it then:
Either install Keil 5.36 first (where it was still) and then update Keil using this distribution to 5.38.
Or install the fifth compiler by hand from ArmCompiler5Last.msi and then add it in the wilds of kale tinctures


Platform : Windows 8.1, 10, 11 (but it seems to work on the seven 1 , 2 , 3 ). Allegedly, support for 32-bit Windows is not guaranteed (but 1 , 2 , 3 works for people )
Minimum: 1 GHz, 1GB of memory, 2GB of disk space; recommended: 2+GHz, 4+GB memory, 5+GB disk space.
