REMCU Lib

The REMCU Lib is a cross-platform library designed for remote access to internal peripherals of various MCU and SoC as if these peripherals were a part of your computer. The library gives access a user space program to all peripherals of the remote chip through the same API as peripheral drivers from Software Development Kit (SDK) provided by semiconductor chip vendors or third parties for MCU firmware development. Thereby a developer doesn’t need to learn new tools but can just reuse his firmware code and examples of the SDK in his code designed for personal or embedded computers. Firmware and protocol communication development are not required, because the REMCU Lib translates itself the local API function call on computer to the call of the same function of peripheral driver on the remote chip.

Let's have a look at the video below and see what opportunities and applications it provides.

remcu_examples's Issues

where an engineer/programmer can apply your product?

Hi, I do not fully understand your project advantages as compared with Arduino/CubeMX code generators and etc? You can write quickly simple projects with Arduino (even schoolchildrens work with it); code generators also lower entry level in "mcu world". Arduino - fast, but bad performance, CubbeMx - more difficult, but better performance.

Struggling with custom OS.

Hi,

Thanks for making the library available. My issue is I get lost after I start the pi with the REMCU custom OS. The interface is cli and I'm struggling to get a connection on wlan0. Is there no way REMCU can be used on normal Raspbian, or that the custom OS can have GUI or working Wi-Fi?

Kind regards,

Dan

STM8L-Discovery Jupyter Notebook examples. GPIO, LCD controller, ADC, DAC, DMA

Hi,

https://github.com/tanbras/MCU_Experiments
This is my REMCU notebooks for STM8LDiscovery board. I want to share these examples for making it easier to learn STM8L chip.

I are looking forward to your confirmation.

How to deal with peripheral interrupts? Use semihosting mode?

I noticed that the example did not mention how to handle interrupts generated by MCU peripherals. I think interrupts are not supported in current cases, is that right?

How receive data quickly from a mcu board?

Hi, if I understood correctly, you receive data from ADC from mcu board via SWD/JTAG debugger. What can you say about performance/bandwidth of this method? Please, give examples of real measurements.

Why is 6 bytes a minimum read and write, use remcu_loadFrMem/remcu_store2mem. instead of 4 bytes or other？

#define MIN_MEM_OPERATION_SIZE 6

Is there any scope to support nRF52 BLE chips

I just see the remote mcu have examples with STM chips, how we can add other mcus such as Espressif or NRF. Thanks.

NanoPi Neo Allwinner H3/ H5

Hi,
very cool project!
Is there also a shared library for Nano Pi Neo boards/ Allwinner CPUs?
