Re: PIC32 vs STM32 2015/12/27 02:12:24 3 (1) You say that you need fast I/O access - Depending on what this is for you might look for a processor that can handle this directly in the hardware (DMA and/or peripheral) which will be faster than bit banging. Library for the LiquidCrystal LCD display connected to an Arduino board. Some of the differences between these two modules are extracted from the datasheet of the F051 chip and presented in the table below. #MicroPython SSD1306 OLED driver, I2C and SPI interfaces created by Adafruit import time import framebuf # register definitions SET_CONTRAST = const(0x81) SET_ENTIRE_ON = const. Arduino library for controlling Serial-based ultra-bright LED pixels and strip. You can google the addresses for your LCD Type. To be able to interface the serial LCD with arduino, you will have to download this library and save it into your Arduino's libraries. The library can be used with other LCD sizes as long as the controller is HD44870. zip library file.
