Although we call then timers whats a timer really is is a hardware counter. It can count up or down and it will count 1 step every time the input clock ticks. These timers can have input clocks in the MHz. How the timer can be used to count encoders is that 2 encoder pins go through some logic circu...

Using software python interrupts to count encoders works fine as long as the freq at which the encoder tick at is low. You will notice that at the repo it has a pic of a dial that just gets turned by hand and will only have low tick freq. If you want to count a fast encoder you will need to use the ...

note: I also plan to allow Pin class objects to be passed into the initializer (that is a best practice in MicroPython and I should have implemented this long ago).

Yer I like it like that and the same if the driver needs I2C that you pass an object rather than the pin numbers

for Pyboard, it it is a string like "X1" Yes, this is the what I haven't figured out. The rotary encoder module requires an integer, but the pyboard pin name is a string. The encoder module documentation example is for ESP32, but the documentation also says that the module was tested with a pyboard...

The ESP32-C3FH4 includes 4MB of internal flash. Micropython GENERIC_C3 is configured for 4MB as well. ESP32-C3.png Thanks for your reply. I notice on the download page there is 2 different bin files for the ESP32 C3, 1 with USB and 1 without USB. Looking at this little board I can't see a UART to U...

I have ordered 1 of these https://www.banggood.com/ESP32-C3-Development-Board-RISC-V-WiFi-Bluetooth-IoT-Development-Board-Compatible-with-Python-p-1914005.html?cur_warehouse=CN&utm_design=18&utm_email=1644394927_2332&utm_source=emarsys&utm_medium=Neworder171109&utm_campaign=trigger-order&utm_content...

Instead of using WebREPL you can use your own sockets to send data from the ESP32 to a python script on your PC over WiFi. I used this method before and got the idea and basic code from here https://stackoverflow.com/questions/59295166/how-to-send-real-time-esp8266-data-through-socket-every-10ms-ern...

OK I have finally worked out the strange behavior with WebREPL on ESP32. It seems the behavior is caused by me using Thonny IDE. It seems Thonny IDE puts the ESP32 boards REPL in to a constant paste mode with echo off and this applies to both UART/USB REPL and WeREPL. If I use PuTTy as a terminal th...

Pwm on esp32 is now fixed.

Thanks Robert, I downloaded v.18 and tested it and it worked perfectly for me

WOW the Lolin boards with 2MB of PsRAM are super cheap and when you buy a batch of 30 the shipping comes out really cheap. I have already brought a 30 of the original style ESP32 boards https://www.aliexpress.com/item/1005001929935550.html?spm=a2g0o.order_list.0.0.21ef1802mqhfC4 In the future I thin...
