Re: [SOLVED] Volatile Qualifier

it is great to know that steve tracked the problem down and found a wordaround for it! :D

IMHO since i am a lover of the clean code, i would do as pito did, if it is easy, it works, why don't change it?
i always think that this is work we are cut off from the future

Re: stm32f103c8 or esp32 for a datalogger

$10 per board is still 500% more than the cost of a < $2 blue board. Op is not building a quad-copter, just some data logging and a few sensors and possibly a future WiFi interface. yep, the f103 is enough for this there is likely the port requirement for the desired libraries. i already have the c...

a) I think you are off by an order of magnitude. My readings suggest 30mS with a necessity approaching 50mS.

Re: stm32f103c8 or esp32 for a datalogger

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 Ray i just discovered about the revision in esp32 but for now i think that the 3 euros le...

Re: stm32f103c8 or esp32 for a datalogger

hi ray, yep the two schools of thought represent perfectly my problem. usually, in my experience, when there are different schools of thought none is the only correct but all have part of reason also the price is something to keep controlled, esp32 is 7€ while bluepill+esp01 is 3€ to be honest i thi...

Re: stm32f103c8 or esp32 for a datalogger

by the way i will also use the wifi with virtuino to control some function of the datalogger (like start the log, stop it ecc) and to show some data on my mobile phone

nono a very basic "start recording"
in the case of the esp01 i will do it with AT commands.

stm32f103c8 or esp32 for a datalogger

hello, I am working on a datalogger for suzuki/kawasaki motorbikes. I have it already working on a bluepill, it uses 2x SPI (SD and MPU9250) and 2x UART (GPS and a L9637 [it is an ic used to talk with the ECU]). But yesterday i had the very very bad idea that i would like to have camera control (lik...
