Fonts

Can you explain how you generated the font file? What has to change for different font sizes to be used in the ST7533 driver? Thanks!

How to build and install on esp32c3

Hi,
Thank you very much for the repo!

I am new to micropython and trying to play with a st7735 display on esp32c3 and set up micropython with mpremtoe enabled,
next I am trying to run some display test but failed with some errors.

Can I import the libs via mpremote? How can I do it?

My test:

Basic:
esp32-dev-micropython#cat hello.py 
print("hello")
esp32-dev-micropython#mpremote run  ./hello.py 
hello

---
dispaly:
esp32-dev-micropython#mpremote run  ./hello.py 
hello
esp32-dev-micropython#cat st7735-test.py

# 由于ftf屏的颜色有问题，因此需要重写一个函数修复一下

MicroPython Joystick driver issue

Dear @GuyCarver , i have tried joystick.py in my micropython (v1.9.4-7-gaeaace07 on 2018-05-13) installed ESP32 board. I have found some inconsistencies when i start getting values. You can see in attached photos below; I will be glad if you let me know about the issue, Thanks...

This is my main code;

from machine import Pin
import Joystick
import time

x_pin = 36 #ADC PIN - (VP ON BOARD)
y_pin = 39 #ADC PIN - (VN ON BOARD)
button_pin = 5 #DIGITAL PIN FOR BUTTON

j = Joystick.Joystick(x_pin, y_pin, button_pin)

while True:
    j.update()
    print("x:", j.x, "button:", j.button, "y:", j.y)

    time.sleep(0.1)

Typo GY521, see link

Hello there, while adapting your class to work on the rp2040, I found a small typo:
'accel' class has no attribute 'setfulscaleaccelrange', should be 'setfullscaleaccelrange' see

MicroPython/lib/GY521.py

Line 380 in cb95afd

self.setfulscaleaccelrange(_ACCEL_FS_2)
