Re: CC3100-Boost demo board

Hi, I have the CC3100 ported onto the MP platform. I am able to use just about all the network/socket module functionality. TI has made major changes, from the CC3000 to the CC3100 so don't expect them to be compatible even with the SPI settings. I integrated the SDK based on the 0.5.2 service pack ...

Re: Sainsmart ST7735 LCD display

Hi, I just modified the stock LCD driver in MP (but the C code) and I thought to share with you some notes to get you going: - make sure you have the pins connected appropriately - make sure the SPI bus is not shared with other devices (if it is you need to make sure the CS lines are connected and i...

Re: Internal flash capacity

That could be a good solution. I think it would a useful option in general due to the high potential of SD Card failures.

Thanks.

Re: Internal flash capacity

Thank you for your prompt response. I am currently having issues with corrupt SD Cards due to occasional power interruptions (will have an eventual solution), so I was trying to reduce that by moving some files into the flash (to store files) used only for reading. Looking again at the linker file h...

Internal flash capacity

Hi, the internal flash capacity of the microcontroller is 1MB. Checking the linker file 512K are allocated for text (code). So we should expect to have 512KB for file space onto the internal flash, but effectively the flash is becoming full after hitting a limit of about 90KB or so. Can someone prov...

Re: OSError: [Errno 5]

I am more of an embedded developer than a high level programmer. So I understand your concepts, but in Python in many cases it is not as straightforward to think that way, but I will use whatever MP has to offer now that this functionality is available.

Re: OSError: [Errno 5]

Ok, thank you for staying engaged on that issue. I will wait for the fix on the main branch. The way I see it, the potential is still high to break the application when manipulating blocks of memory, which is a fundamental part of a scripting language. One way would be to have a lot of free RAM, tha...

Re: OSError: [Errno 5]

So for the moment it is not possible to defragment memory.

Re: OSError: [Errno 5]

Well thank you for the useful feedback. I think most users will face this problem, there are ways we can reduce the fragmentation with pre-allocating buffers, but eventually we will need this flexibility. If there is something we can do about running a process periodically to get the memory chunks m...
