Re: STM32WB - dualcore with 2.4GHz radio

basically i read it as ST is now getting serious about bluetooth LE and its integration with mcus :D it sounds like we're going to get an 'abusive' 'explosive growth' of everything bluetooth LE, mouse, keyboards, fitness trackers, smart watches, beacons, sensors, lights, drones, vending machines, 3d...

Re: STM32WB - dualcore with 2.4GHz radio

when i take a closer look at the sku i noted something similar to TI's CC2640 :lol: http://www.st.com/content/st_com/en/products/microcontrollers/stm32-32-bit-arm-cortex-mcus/stm32-wireless-mcus/stm32wb-series/stm32wbx5/stm32wb55cg.html http://www.st.com/content/ccc/fragment/product_related/rpn_info...

Re: STM32WB - dualcore with 2.4GHz radio

think 1 day we'd have 4,8,16,64,1024 cores stm32 mcus, we'd be able to compete head on with fpgas with all that arm mcus :lol:
oh and much more important is that 2.4 ghz BLE capable radio, finally ST tries to live up to compete vs nrf51822 & esp32 :lol:

Re: Lightpen

my guess is that a photo-transistor may be sufficiently sensitive to trigger a logic 0 or 1 with things like: vcc|----photo_transistor-----+-----resistor---------|gnd ^-- and we simply feed this to the gpio pin what may be needed is to shield it from 'stray' light then we can possibly 'draw a patter...

Re: STM32F1/F4 3d Printer board. Worth a kickstarter?

imho for now some 'public domain' or open sourced slicers mainly produce g-codes that basically breaks curves and angular joints perhaps into straight lines. my guess is that most of the commands would be 'simple' commands that's intended to complete a 'straight line' manoeuvre. The breaking into st...

Re: STM32F1/F4 3d Printer board. Worth a kickstarter?

common g-codes apparently simply use integers https://www.simplify3d.com/support/articles/3d-printing-gcode-tutorial/ however, if the controller board does movement optimization across a series of g-codes, my guess is it can do a lot of calculations for the acceleration, constant speed, deceleration...

Re: STM32F1/F4 3d Printer board. Worth a kickstarter?

i think there'd still be a mkt for the 'board only' attempt, but then the target crowd would be those who have an existing printer & wanted to swap the controller for something else, even if it is somewhat pricier there may still be buyers given the correct niche, some may simply want to replace 16 ...

Re: STM32F1/F4 3d Printer board. Worth a kickstarter?

i think the board alone would see quite a bit of price competition, as chinese 3d printer kits sells for under usd $200 these days for a complete kit. there have been some success stories (not necessarily via kickstarter), like the replicape that pairs up with a beagle bone black https://www.thing-p...

Re: Proposal. Use forum logins on the wiki

i'm rather surprised that spambots these days are so intrusive, i''ve not been aware of these as i'm not running a forum or such web myself. but i did note that some spambots search forums etc for email addresses e.g. looking for the @ symbol and i did get spam coming to my email , i've been careful...

Re: Serial Port for USB on the MAPLE-Mini ?

i've got this sketch for a simple minded usb-serial dongle,
viewtopic.php?f=18&t=2752
i don't really implement the RS232 signals, rather i simply hard coded the interface at the uart end of it
on the usb side, the signals actually won't matter
