Re: comparison 1-1/3 <> 2/3 microPython VS Python 3.7

Re: PWM on separate timers

Hello,
I don't think so.
I can't find the information but I have tried to use separate PWM frequencies for steppers motors and finally I have read somewhere that it was not possible on ESP32 boards.
If you can, I am interested to know how do that ... ;)

(www.Thonny.org) it works very well on MacOs. esptools are included In the menu you have [execute / choose the interpreter and then at the bottom you can chose the microsoftware you want to flash to the b...

Re: ADC settings bug

I agree. I prefer to use an external ADS1015 or ADS1115. It allows to have 4 analog inputs with choices of settings more advantageous than what the ESP32 would allow (differential inputs, programmable gain, sampling). I directly introduced the converter into the connection cable. And micropython lib...

Re: 24LC512 I2C memory

Since last month I didn't knew FRAM memory that is why I have chosen an eeprom memory until a FRAM one. But with your driver it is not a problem now every thing works perfectly ;) Your work on the FRAM memory is so interressing that I have ordered some of them : FM24CL16-G FM24CL16 sop-8 16Kb FRAM S...

Re: 24LC512 I2C memory

Thanks a lot for your answers.
I will have a look next week. I haven't got the choice, I have to find a solution, the eeprom is soldered on the board :roll: and I bought about twenty :?
I will come back soon
