I need a timestamp in millisecond in linux epoch. It is a number that doesn't fit in a 32-bits number. I'm using a 32-bit MCU (STM32L4R9...) so I don't have a 64-bits hw counter. I need to create a mixed sw/hw 64-bits counter. It's very simple, I configure a 32-bits hw timer to run at 1kHz and increment an uint32_t variable in timer overflow ISR. Now I need to implement a GetTick() f...

I'm a good programmer in just about any computer language you can mention. But for example, I don't know how to use the multitude of protocols to talk to the various types of hardware. Some easy examples of these protocols are the 1553 bus and UART. There are many more that I could list. I'm looking for a well-rounded course or courses to learn Embedded Programming. What should I learn? What...

Maybe I'm stuck in my ways like a dinosaur, but I've always liked my Codewright editor. My latest PC would not take my previous installation of it though and I had to start fresh. But that means a lot of stuff that worked before doesn't work now. This is ver 7.5, that latest. I don't know exactly how Windows makes the connection when you click on a file type to open it in the

I noticed my previous post about preemptive OS involved many people and started many discussions, most of them theoric. Someone wrote the synchronization of tasks in preemptive scheduler is not so difficult, after understanding some things. Others suggested to abandon at all preemptive scheduler, considering its pitfalls. Because I know my limits, I don't think I can produce a well-wri...

I have to connect ADV7280-M (contained in the EVAL-ADV7280MEBZ board) board to Rock Pi 4B SoC. I have recompiled the kernel with added adv7180.c driver. The procedure for recompilation of the kernel I have taken from: https://wiki.radxa.com/Rockpi4/dev/kernel-4.4 After that I had to add ADV7280-M to the device tree. /dts-v1/; /plugin/; / { model = "RO

I have always worked on non real-time systems, i.e. when the reaction of the system to an event should occur in a reasonable time. For example, when the user presses a button, a motor should start rotating. If the motor starts after 100us or 100ms is not so important. I never used RTOS, so the architecture of my firmware is based on "superloop technique" (background tasks running in the...
