Description

So I am using Thonny and installed this library and ran the slave code with Wemos d1 mini esp8266, Wemos W600-pico and the Raspberry Pi PICO. The code ran fine with the Raspberry Pi Pico. However, both the Wemos W600-PICO and ESP8266 ran into trouble with memory allocation.

Reproduction steps

1.Install the umodbus library on Micropython via the manage packages in Thonny
2. Copy/ paste the RTU slave code in it.
3.Run the code
