This post show how to display on  0.96" 80x160 ST7735 SPI IPS , with  Raspberry Pi Pico W /MicroPython, using  boochow/MicroPython-ST7735 library . The original boochow/MicroPython-ST7735 target 128x160 ST7735 TFT LCD driver for MicroPython. This post show steps to install the library, and modify it to fix screen size, offset and color. Please note that the modification base on my own guessing and trying, not any official suggested approach.

Last post show my first test HC-25 WiFi Module, with AT Command; act as AP, setup socket server . Here is my exercise using Xiao ESP32C3 (in arduino-esp32 framework) to implement the client side: act as STA, join HC-25 WiFi network, connect to HC-25 socket server, receive and echo back in upper case. Exercise code: XiaoESP32C3_TCPclient.ino /* A simple TCP client run on ESP32-C3, * connect socket server run on HC-25 as AP. * * Have to set WAP in HC-25 using AT command: * AT+WMODE=AP * AT+WAP=myHC-25,password * * 192.168.4.1:8080 is the socket server on HC-25 */ #include <WiFi.h> // AP of HC-25 const char *ssid = "myHC-25"; const char *password = "password"; // server IP and port const IPAddress serverIP(192,168,4,1); uint16_t serverPort = 8080; WiFiClient client; void setup() { delay(200); Serial.begin(115200); delay(200); Serial.println("\n\r- Socket Client run on Xiao ESP32C3 (arduino-esp32) -"); Serial.printl...

HC-25 WiFi IoT module supports TCP, UDP, HTTP, MQTT ~ Product Page : include various information about HC-25 WiFi Module include Specification, AT Command Set, and various Utilities (currently in Chinese) First test HC-25 WiFi Module, with AT Command, as Socket Server: Once setup as in the video, the HC-25 act as AP (with ssid/password = "myHC-25"/"password", and setup socket server at 192.168.4.1:8080. Following are exercises to implement client side in various platform to connect to the HC-25 socket server: ~  Xiao ESP32C3 (in arduino-esp32 framework) act as socket client, connect to HC-25 WiFi Module . ~ Raspberry Pi Pico W/MicroPython act as socket client, connect to HC-25 WiFi Module . ~ ESP32-S3/CircuitPython act as socket client, connect to HC-25 WiFi Module .

CircuitPython 8.0.0 Beta 5 released .  A one-line status bar added to displays connection status, last exception, and version on a terminal window title or on the top line of an attached display. It need Mu 1.2.0 or Thonny 4.0.x and later to suppress status bar information in the REPL output. Currently on Linux Mint 21, the Thonny available to be installed with apt is ver 3.3.14, not the most update 4.0.1. Refer last post " Install Thonny 4.0.1 on Linux Mint 21 ". Raspberry Pi Pico W with CircuitPython 8.0.0 Beta 5, work with Thonny 4.0.1. Work on Raspberry Pi Pico with CircuitPython 8.0.0 Beta 5, one-line status bar added on top of attached display ST7789.

Currently, the Thonny available to be installed with apt is ver 3.3.14, not the most update 4.0.1. To install Thonny 4.0.1 Visit Thonny page: https://thonny.org/ For Linux, download "thonny-4.0.1.bash", and make it runnable as program. Run in Terminal $ ./thonny-4.0.1.bash
