Everyone has been through this: Minimal C++ application for ARM mс. (Cortex-M3) Let's start creating one very important application: it must compile successfully; the result should be code that will run correctly on the mc. In this case, the program will not perform any useful work. The importance of this minimal application is that it allows you to verify the functionality of the development tools used and is the basis (template) for more complex projects. To work, we need a mc. and development tools. The easiest way to start experimenting with microcontrollers is to use some kind of evaluation board. This eliminates the hassle of soldering; There is no need to worry about providing the mc. with proper power supply or quartz stabilization. The evaluation board already contains the main external circuits necessary for the normal operation of the mc. - just what you need to immediately start experimenting. Which mc. is chosen is not so important, especially if we are talking about a minimal application. Let it be a device based on the Cortex-M3 core. The minimal program is extremely simple, consisting of a single user file containing the definition of a single function, main. /* * File: main.cpp * VECT_TAB_SRAM */ #include "stm32f10x.h" int main(void) { int i = 0; while (true) { i++; } } Since there is little benefit to increasing a variable by one in an infinite loop, the user code for a minimal application might look like this: /* * File: main.cpp * VECT_TAB_SRAM */ #include "stm32f10x.h" int main(void) { while (true) {} } The first version of the program is more fun to debug (at least something happens in the program), while the second version is more minimal. In truth, the line #include "stm32f10x.h" can also be excluded, since no descriptions from stm32f10x.h are used in the main.cpp file. But still, we won’t do this, since usually any program more complex than the minimal one requires access to the periphery, therefore, including a file like <device>.h is necessary.

Today I'm releasing Spade 0.8.0 🎉 This release extends the standard library, fixes a whole bunch of small pitfalls, and includes several improvements around tests! The standard library now has a higher level wrapper around #fpga block-rams, primitives for clock domain crossing, and reduce_* functions added by @0xC01DC0FFEE Finally, improved #Verilator support allows cool stuff in tests. The video shows this being used to visualize memory accesses in my camera project Blog: https://lnkd.in/dMzbQ_-E If this is your first time hearing about Spade, it is a hardware description language that makes hardware design more productive, less error prone and more fun by drawing inspiration from modern software languages, especially #rust A few weeks ago I gave a talk at Latch-Up which has a good overview of the language https://lnkd.in/dZCj5bBW

The ���𝗿𝗶𝗻𝘁𝗳() function is commonly used in embedded development. It provides a convenient means to send logs or debug statements from the system to a terminal on the host. A number of printf methods on Cortex-M MCUs are discussed in this article, including UART and Semihosting, to empower developers with crucial information to enhance their development processes and improve the reliability of their systems.

The design process of a program for an embedded system has two main steps. The first step is to build a program which is done on a build system that consists of complier, linker, assembler, debugger and libraries. Developing a program on build system begins with creating source files. Then compiling, assembling and linking with a linker file, libraries. Finally, this process of program code and data results in an executable file; I call it "the spirit". At this point, the program is ready for the second step; installation and testing. Installing the executable on the hardware platform which I call "the body", is done by writing instructions in the code into flash memory, and writing dynamic datas into RAM. A bus connects those memories and CPU together to make CPU possible to interact those instructions and datas. Then, testing all functions and features is done, which is important not only for functionality, but also for performance, reliability and maybe safety critic aspects. This process is likely to arrive to countless iterations until everything works as expected. Once you are at this point, it is like giving a spirit to a body; the hardware is alive.

“The only reasonable way to build an embedded system is to start integrating today. The biggest schedule killers are unknowns; only testing and running code and hardware will reveal the existence of these unknowns. Test and integration are no longer individual milestones; they are the very fabric of development.” From The Art of Designing Embedded Systems [Gan00], by Jack Ganssle #EmbeddedSystems #Test_Driven_Development

Can we use MLIR and  LLVM framework in hardware design tools? An option could be CIRCT - Circuit IR Compilers and Tools.

#100daysofrtl Day 004: 8bit Encoder. In the day 004 of my RTL challenge, I designed the 8bit encoder using the verilog hdl. The encoder is designed for the 8bit and the test bench is written to verify the correctness of the design code. An encoder is a digital circuit that converts a set of binary inputs into a unique binary code. The binary code represents the position of the input and is used to identify the specific input that is active. Encoders are commonly used in digital systems to convert a parallel set of inputs into a serial code.
