Re: F405 & F411 versions of the BluePill

Just one remark to the "SD-card exchange problem": To exchange the SD-card on the bottom side when the F4BP is soldered is probably impossible. <...> On the surface, your argument is sound. The reality is that I have been playing around with the rPi_Zero-W since they were first available, and it is...

Re: Greetings from overly sunny brisbane.

<...> Ray, sparkfun have an interesting read on re flow. Their (and many others) preferred device is an electric skillet. I find this astounding as I have never seen one that can heat anywhere close to evenly. <...> From my readings, one should use clean, dry sand to provide a layer of heat distrib...

Re: stm32f103c8 or esp32 for a datalogger

a) You have to release the code, that means "do the internes stuff to keep the connection going" with yield() or delay(0) i have read that it is suggested every 200milliseconds to be very safe. Mandatory every 500 b) Ray i just discovered about the revision in esp32 but for now i think that the 3 e...

Re: stm32f103c8 or esp32 for a datalogger

<...> Sorry for sidetracking the thread, but what did you mean with that, how to you release the code? with a delay() perhaps? I don't have experience with the ESP yet, but was thinking on using one for a humidity logger. My code should take less than 50ms to read and go back to sleep, but I'm curi...

Re: Curious in Colorado

Just thinking... There is possibly another solution. Paul @PJRC.com has spent years working on the competitive Teensy line of boards, most around the NXP/Freescale products. His core code is open sourced as are the libraries and many of his concepts have been retrofitted into the Arduino.cc official...

Re: stm32f103c8 or esp32 for a datalogger

<...> also the price is something to keep controlled, esp32 is 7€ while bluepill+esp01 is 3€ to be honest i think i will stay on the stm32, i like the mcu, i like the repo, i like the forum <3 :lol: <...> Recent reduction in ESP32 prices for Rev 1 silicon: https://www.aliexpress.com/item/LOLIN32-Wi...

Re: Hello from Saarland

archimedesmp, welcome! We have several German members in the forum.

The blue board is fairly well represented, second only to the Maple Mini ... well, it could actually be the #1 population at this time.

Good luck,

<...> ... you will find that they are much more powerful than your typical 8-bitter. Obviously, you can have different sorts of ECU boards with different sorts of capabilities but going with a generic 8-bit for an ECU can be challenging. <...> The Op's original intent was stated I used that 328p in...

Re: Serial buffer

<...> I'd think these are issues that could be addressed in order to make a better core, one option could be moving the buffers in the variant files. Yes, the Boards.txt file could be modified to pass a variable from a list of pre-determined buffer sizes. Seems a bit silly, IMHO, since someone coul...

Re: Greetings from overly sunny brisbane.

My first project is a re-flow controller. Tim, I seem to remember Roger Clark working on something similar. I do remember he was no having any joy with his Chinese oven, however. I did a quick site search and did not find it, so maybe I'm having a brain-fart. May be worth sending Roger a PM... it c...
