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

Re: stm32f103c8 or esp32 for a datalogger

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...

Re: difference between wire twowire

This is quite a major change (though I agree it does bring the core in line with the internals of the official Arduino core) I will need to wait for significant testing by everyone and also feedback via github and here This change needs its own thread Ok, would you mind to open the thread? English ...

as you can see from the immage we will break just 2 codes: one is a example for the ssd1306 and the other a version of the famous i2c_scanner which will work anyway
i think we could handle this

Re: difference between wire twowire

So if i am not wrong: WireBase is the actual library which do the i2c stuffs (in arduino is twi) Wire is exactly the same as Arduino's Wire Ray, i am just an hobbiest so i am the last person who could take word over a programming problem but the arduino core is powerful, it s not anymore true that a...
