ROHM – Bluish-purple tech

SPI on the Raspberry Pi Pico The RP2040 has two independent SPI controllers (SPI0 / SPI1), available on the Raspberry Pi Pico from GP[0] to GP[27] pins. In this article, I tried to use this feature to connect the LCD display and read/write the EEPROM. Connecting the ATM0130B3 LCD The ATM0130B3 is a 240x(RGB)x240 1.3-inch full-color graphic LCD. This time, we used Akizuki’s control kit with 2.54mm pitch conversion board to connect it. The pitch conversion board also has a level conversion circuit, so it can be connected directly to the Raspberry Pi Pico. 1.3-inch full-color graphic LCD display Hardware connections The following figure shows the wiring between Raspberry Pi Pico’s I/O terminals and the ATM0130B3 conversion board. All the necessary components are mounted on the board. Connect the four SPI pins /CS, D/C, and RES, and the power supply and GND pins, respectively.

I2C on the Raspberry Pi Pico The RP2040 has two independent channels of I2C controllers (I2C0 / I2C1), which are available on the Raspberry Pi Pico from GP[0] to GP[27] pins. In this article, we tried to use this feature to read and write the digital temperature sensor and EEPROM. Connecting the TMP102 digital temperature sensor module The TMP102 device is a high-precision digital temperature sensor made by TI, with a built-in 12-bit ADC, a minimum resolution of 0.0625°C, and an accuracy of ±0.5°C without calibration or signal conditioning by external components. Here, we will use a SparkFun modulewith this temperature sensor IC and peripheral components (I2C pull-up resistor, etc.) to connect to a Raspberry pi pico. TMP102 Module Hardware connection The wiring between the Raspberry Pi Pico I/O terminals and the TMP102 module is shown below, and the I2C pull-up resistor and other necessary components are already mounted on
