+# MicroPython for PicoCalc
+
+Here is pre-compiled uf2 files for micropython running on PicoCalc based on [PicoCalc-micropython-driver](https://github.com/zenodante/PicoCalc-micropython-driver)
+
+- micropython_pico.uf2
+- micropython_pico2.uf2  
+- micropython_pico2w.uf2 
+
+These uf2 files already included main.py ,so just put into PicoCalc , you will get a python running terminal immediately   
+No need to use Thonny , for those who interest to try python.  
+
+For developers, just visit [PicoCalc-micropython-driver](https://github.com/zenodante/PicoCalc-micropython-driver)  
+
+Follow the readme to  
+- Flash firmware and upload python code through Thonny IDE. 
+- Compile custom micropython firmware for picocalc.
+
+
+Here is the Sequence for beginners to run python on Pico with PicoCalc:  
+
+1. Put pico into BOOTSEL mode.
+2. Flash correct firmware uf2 file included all necessary python module.
+3. Open Thonny at the mean time, config Interpreter with correct kind and port (usuall /dev/ttyACM0 on linux).  
+4. Upload main.py( this is the entry boot up python file) and other py files to /. from left sidebar.
+5. Do nothing but wait for uploading finished,then unplug the Micro-usb cable from pico.
+6. Plug USB-C cable into PicoCalc and Power On to see if everything goes right.
+
+here is the sample screenshots about thonny:
