Pin Multiplexing on the Seeed Studio XIAO RP2040 The Seeed Studio XIAO RP2040 contains 11 digital pins, 4 analog pins, 11 PWM Pins,1 I2C interface, 1 UART interface, 1 SPI interface, 1 SWD Bonding pad inter
Adafruit Feather RP2040 Adafruit Feather RP2040 Product ID: 4884 A new chip means a new Feather, and the Raspberry Pi RP2040 is no exception. When we saw this chip we thought "this chip is going to be awesome when we give it the Feather Treatment" and so we did! This Feather features...
Multiple interfaces:One I2C, One UART, One 2x3 Pin SPI Interface Here is a new member of the CAN Bus family in Seeed, let's shed some light on CANBed DUAL! CANBed DUAL, a CAN Bus development board, is based on the RP2040 chip which is the debut microcontroller from...
//#define RP2040_PIO_CLK_DIV 3 // 96ns write cycle at 125MHz CPU clock // For the RP2040 processor define the SPI port channel used (default 0 if undefined) //#define TFT_SPI_PORT 1 // Set to 0 if SPI0 pins are used, or 1 if spi1 pins used // For the STM32 processor ...
There is 25 multi-function GPIO pins on the Pico, including communication ports like I2C, SPI, and UART, along with 8 programmable I/Os and so on. Equipped with an enhanced RP2040 chip, it can perform everything you need in IoT-controlling projects. And because of its small size and fi...
If the SD card is the only SPI device, use dedicated SPI mode. This can greatly improve performance. See the bench example. Here is write performance for an old, 2011, card on a Due board. Shared SPI: write speed and latency speed,max,min,avg ...
The RP2040 8-bit parallel interface uses the PIO. The PIO now manages the "setWindow" and "block fill" actions, releasing the processor for other tasks when areas of the screen are being filled with a colour. The PIO can optionally be used for SPI interface displays if #define RP2040_...
然后准备一块屏幕,我使用的是一块2.8寸(240*240)的tft屏幕,驱动是ST7789,使用spi通信协议。 二、软件准备这里我使用的是vscode 的PlatformIO插件 新建文件,选择开发板为DOIT ESP32 DEVKIT V1,还有保存路径。 在Libraries这里添加库,我们需要导入TFT_eSPI和TJpg_Decoder两个库,TFT_eSPI是一个功能强大的TFT屏幕驱动...
