Dear Roberthh, thanks a lot! What you said about BytesIO and open really cleared up my mind. Thanks! Regarding files and RAM, if I understood correctly, you suggest that I exploit the advantages of IO type set of methods and i.e. you suggest that I break the file into many partial ones or use method...

Once again thank you for your precious help! The open("filename.txt", ..) seems to work ok. At least I can see it in the /flash directory. Now a couple of questions (it seems like it's never ending with me...I'm sorry): Let's say that I have a file stored in flash memory which has a size bigger than...

Hahaha, don't worry I feel the same...Especially now cause I still don't get it... First of all the calculation data[1]*data[3] = 313344. [This imply that you multiply fragment size(the what?) times # of free blocks] So, you mean that the result, 313344, is bytes (?) or approximately 314KB which is ...

Hi Roberthh! Thanks a lot for your response! Thank you for clearing up that statvfs tells nothing about the RAM. May I ask how did you get to the conclusion of the file system size (you said it is 6130 KB?), just from statvfs's result? Well, maybe it's not of great interest to you, but from what I h...

Oh, well regarding the block device, I have found that: MicroPython creates the VFS and offers the ability to mount other file systems(i.e LFS) within this VFS. So, a block device is a custom class (a template of which should be inspired by the uos.AbstractBlockDev class) which can provide me access...

Hey everybody! Being a total newbie, i am sorry in advance for the hard time I am giving you :roll: Let me start quoting the following from the MicroPython Documentation: "The file system is typically backed by internal flash memory on the device, but can also use external flash, RAM, or a custom bl...

Hey everybody! This is as well, my first post! Thank you all for your precious help ! Keep up the good work! One question from me, regarding where to post a new topic. Feels like I am not sure where to post my question. In case of posting it under "wrong" category, is there any chance of moving it a...
