![]() the memory sizes to be used for flash and ram. ![]() In this case the difference to change should be: In the mean time, a friend of mine that was building a corexy tried my code with is corexy "skeleton" and some basic GCODE tests, with good if you want to try this port on your NUCLEOF446RE you may do it quite easily, because one good thing is that it uses the libopencm3 that allows to easily recompile for another target, and the pinout of the two boards is not so different (I should re-check it, but at a first view it seemed very similar). The reason for this is explained in the wiki of the repository. There are just a couple of inputs that are reconnected on the morpho pins (the non-arduino connectors) or something similar, but not the driver outputs that are the most important thing to drive with the shield. ![]() Indeed, as I pointed out in the first post, I have tried to keep the pinout as similar to the arduino as possible to use a shield. Last edit at 10:29AM by adc_dc.Įffectively I am using that shield to make some tests with a cheap scope, some driver and a stepper motor I have. in a flash and managed without any information loss, or so it seems from my testsįor any question feel free to contact me here or on the project.Įdited 1 time(s). the settings and other informations are stored in a NVM "Non Volatile Memory", i.e. I used libopencm3 library, to make the code portable also on other supported board, as an example most of the boards that have STM32 processors. I tried to use the same pinout used by GRBL to have the possibility to re-use the existing motor driving shields with just few reconnections ![]() the 32-bit processor runs at 48 MHz (and it may run at 84 MHz, but for now I used an easily manageable frequency), while normally the arduino's CPUs run at16 MHz, if I am not wrong. Moreover, if somebody owns a NUCLEOF401RE board, and would like to use it, here is the repository link with a bit of informations: These test, up till now were positive, but I realize that I would need more testing and if someone knows good stress tests I'd appreciate it very much. I am new in the forum, but I read it before every now and then.Ī bit of time ago I obtained a NUCLEOF401RE board, that is quite cheap but powerful, and I played with it and with GRBL and some motors I had, and I started porting the GRBL v.0.9 code on the cortex processor.Īfter a bit (or a lot ) of work I have been able to port the code, and I did a bit of testing with some GCODE files and control software on host(GCODEController or UGS). ![]()
