News...

 I published my first post on this blog in October 2020. For more than a year, I regularly posed diverse and varied subjects. During this period, I noticed that this blog did not interest many people. So to speak, no one.

Without even realizing it, I quite naturally ended up stopping my publications focused more specifically on computing and retro computing on this blog, favoring my other more general blog https://synthelectro-fr.blogspot.com.

A little by chance, I was able to observe recently that the consultations of this blog had greatly increased, despite the fact that I have not published anything new for over a year now.


This motivates me again to revitalize this blog. Especially since during February 2022 (last post on this blog), I studied several projects based on RISC-V processors.

Yes, because until then, I often used ARM processors from STMicroelectronics. But I admit to having difficulty, not with these processors, but quite simply with the graphical resource configuration interface, STM32CubeIDE. I know, this type of software is supposed to greatly facilitate the start of any project, but I find that this approach is a little too 'virtual'.

After all, I'm a guy from the 80s where absolutely everything had to be done 'by hand'. I kept this 'root' approach and I think that this makes it easier to 'become aware' of the operation of the processor used.

I came across the RISC-V processors from Nanjing Qinheng Microelectronics Co. 'fortuitously' and in particular their WinChipHead (WCH) brand.

So I now use the CH32V203 & CH32V307 range of processors.


So, since the beginning of 2022, I have started to migrate my projects to this new series of processors. One of the first examples concerns a 4-channel TIMER, easy to use, intended to be the worthy heir of the famous TMS1122 processor from TI. with some improvements, obviously.

I used this project to really discover WCH processors, and also to implement a concept that I appreciate and that I discovered on Facebook, the minimalist computing.

My Timer publication on the 'Minimalist Computing' group :


I am therefore thinking of publishing now on this blog the progress of my projects based on RISC-V processors.
