From the previous article that has used a 3.5″ display for Raspberry Pi Board to use with ESP32, we also have an Arduino 2.4″ TFT LCD & Touch Shield that is used with Arduino Uno and Arduino Mega (as shown in Figure 1. ) and want to use with a microcontroller STM32F401RET6 Board NUCLEO-F401RE and STM32F401CC (Figure 2), which are Cortex-M4 with 96KB and 64KB memory respectively, ROM memory is 512KB and 128KB, with 8 switches connected to the pin. In this article, Board ET-TEST 10P/INP (Figure 3) is used to replace the left, up, down, right, m1,m2, A and B buttons respectively.
