Re: [POLL (Open)]- favorite STM32F1 board for stm32duino 08/2107

Re: SD / Memory bottleneck, any ideas?

I thought SDIO was the best way to improve performance, but its not available on the Blue pill , and libmaple does not have a built in library for it. Though I thought there was at least one thread on SDIO There is one SDIO for F4. I have looked at it and should be faily straight forward to convert...

Re: RGB lightsaber

Another small update: tested everything except the USB so far on the above boards, and it's all good XD Was struggling with the sd cards a bit, but it ended up actually being an sd card that was broken ^^'.

consider the goods as compensation for bad service or as a penalty clause to a contract :?: :lol:

Re: Aliexpress delivery times

lol, a counterexample just arrived XD
something i ordered end december (and which has been refunded since it never arrived) just arrived XD.
i was wondering what was in it, since it mentioned IC's on the package and i wasn't expecting any XD.
A new record for me i think: 7+ months delivery time.

Software only used to run at 100khz, but I recently reworked it to squeeze it up to just over 400khz, but its highly dependant on the optimisation level in the code, both a...

Aliexpress delivery times

i'm wondering what your recent experiences are with aliexpress delivery times. the last few months normal cheap packages seem to be arriving a lot faster for me (belgium, western europe). a bit over 2 weeks ago i made about 10 orders, most of them arrived already, all standard chinese post shipping....
