agreed the cc254x is pretty much a propriety bluetooth le stack from ti and that ti basically designed the cc2541 based on a 8051 cpu core. i doubt there would be much room for user codes even if we choose to add things in cc2541 and yup the Nordics bluetooth le soc e.g. nrf51822 is pretty much a be...

thanks, i think mechaduino, nano stepper and ustepper are good projects that's pretty much 'been there done that' one of the interesting things about the stepper control projects is the use of PID closed loop feedback control as this you tube video illustrates, it could make a difference in terms of...
actually 8051 (clones) is still loitering around as (rather) cheap *bluetooth LE* dongles :lol: http://www.ti.com/product/CC2541 https://www.ebay.com/sch/i.html?_nkw=cc2541&_sacat=0 and incidentally as well a new fad for sdcc seem to be the stm8s-duino, it seem pretty hot here :) http://www.stm32dui...

if you have a maple mini (or clone, e.g. Baite MM) with a pre-installed boot loader you may like to try out this code i've posted under code snippets section, i'm not too sure if those codes would after all work on other arduinos http://www.stm32duino.com/viewtopic.php?f=18&t=2752 one of those thing...
My own talk was on the last hour of the last day, and followed the popular "Mars ate my spacecraft." So it was sparsely attended. My topic was "Upgrading Legacy systems." Where I showed an 8051 project I converted to the Arduino IDE so it could be connected to IoT. I brought my small pipe organ whi...

well you could get a Baite MM clone instead of BP https://www.aliexpress.com/store/product/STM32F103CBT6-maple-mini-ARM-STM32-compatibility/213957_32674146722.html https://www.ebay.com/sch/i.html?_nkw=stm32f103+maple+mini&_sacat=0 that uses AMS1117 with a max 15V given in the spec and accordingly it...

i'm thinking that in terms of stm32f4 usb host mode, 1 of those ways is perhaps to start with stm32generic core or st's stm32duino core, review the examples from cubemx etc provided by ST and one could implement usb host functionality. it probably isn't 'impossible' just that it'd take one effort to...
