Re: Porting uPy to STM32F446

I guess I am most interested specifically in the STM32F446RET6 The F446 does not have PB11. It requires another cap in the pin for the core voltage regulator. The F411 is the same. Hence you might find it easier to modify pyblite which uses F411. You will loose I2C from pins Y9 and Y10 because the ...

Re: Micro Python development wish list

MTP does not allow file editing, only transfer or open read only. Verified with Android 4 and Windows Phone 8 connected to WIN7 and WIN8. Differences between MSC (memory stick) and MTP (phone) under Windows. 1. Phone does not mount with a drive letter. 2. Windows explorer does not have "New --> Text...

Re: Micro Python development wish list

I would like to see a more robust file system and host file sharing than FATFS and MSC. A journalling, wear levelling file system is much more robust. The first step would be to replace MSC which accesses sectors with a file sharing or transfer protocol. Henrik Solver suggested MTP (Media Transfer P...

Re: Question about 5V tolerant pins.

Pins X9 & X10 are probably not 5V tolerant. They are connected to the on board accelerometer. The MMA7660 datasheet does not have an absolute maximum voltage spec for IO pins, only supply pins, but it is unlikely to be 5V tolerant.
