I have esp32 and nokia 1202 lcd. It uses ste2007 like hx1230.

I couldn't run it. I think I am wrong about esp32 spi configuration. were you able to run it?

Hi. I have a problem. At the beginning, I run 2 tasks with gather. async def ana_sayfa_as(r, ayar): pb.press_func(False) pb.release_func(menu,) pb.long_func(gizli_menu,) sb.press_func(seri,) tb.press_func(tek_at,) async def main(): global a1 global t1 t1 = uasyncio.create_task(rotar(r, ayar)) a1 = u...

Sorry. I type wrong. When I press the button, I want to stop the task and start another task. I want to use callback for this. async def main(): global a1 global t1 t1 = uasyncio.create_task(rotar(r)) a1 = uasyncio.create_task(ana_sayfa()) await uasyncio.gather(t1,a1) first ana_sayfa() will start. I...

Hi. I want to create a menu using uasyncio. I want to write a separate function for each submenu. When I press the button, I need to start the other task with the callback function. however, the previous task must be stopped. Here my codes I get errors about cancel. What should I do. MicroPython v1....

When I use interrupt and interrupt to assign another function, it resets esp32 with machine.disable_irq(). Can you post an example of the code that causes this? i use MicroPython v1.16 on 2021-06-23; ESP32 module with ESP32 Type "help()" for more information. from rotary_irq_esp import RotaryIRQ im...

Anyone using st7920? I am looking for 128x64 lcd with big screen and cheap. If you are using, which library you are using.

I have no more pins on esp8266. I used it for SPI. so I want to run the rotary encoder via mcp23017. I will try EncodeLib modify like this and I will share the results from machine import Pin from machine import Timer class encoder: # Init variables encoder_clk_prev = False i = 0 def __init__(self, ...

Hi, I want using rotary encoder over mcp23017 i/o expander. But esp8266 freeze. I use those libraries: Rotary encoder: https://github.com/BramRausch/encoderLib MCP23017: https://github.com/ShrimpingIt/micropython-mcp230xx import mcp import encoderLib io = mcp.MCP23017() io.setup(8,mcp.IN) io.setup(9...
