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,

Re: Curious in Colorado

<...> ... 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...

Re: problem with gps :( only 0.0000 instead of real data:(

from the PDF user manual: https://www.terraelectronica.ru/%2Fds%2Fpdf%2FU%2FUART%20GPS%20NEO-6M%20User%20Manual.pdf After waiting for a while, if the serial debugging assistant lists similar data in its window as the figure shows below, it means GPS has performed positioning. And you can see that th...

Re: ESP8266 on Blue Pill

<...> I see some examples using esp8266 from your link , so my question sir is how can I send a sensor reading from the "bluepill" pass it to a webserve via wifi module? Sorry for this noobee question but I`m confused right now. The ESP8266 module can act as a client, a server, and Access Point. So...

Re: stm32f103c8 or esp32 for a datalogger

Two schools of thought ... 1) keep what you have STM32 and add WiFi with ESP32/ESP8266 2) integrate all functionality into one uC, say the ESP32 Personally, I have an on-again, off-again relationship with the ESP32. I have more experience with the ESP8266 but the single core and the task switching b...
