ATtiny85 in HW-260 board

I have my ATtiny85 microcontroller installed in a HW-260 development board (purchased from AliExpress). I program the ATtiny85 with the SparkFun Tiny AVR Programmer, the setup guide is here: Tiny AVR Programmer Hookup Guide.

On the SparkFun programmer the onboard LED is PB0. On the HW-260 the onboard LED is PB1. This is the code I used to flash the HW-260 LED:

#define LED_BUILTIN PB1

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);                       // wait for a second
  digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);                       // wait for a second
}

Interlude #11: Playing with WeAct Studio Epaper Modules on ESP32-C3 MCU | In The Lab With Jay Jay

In this video we play around with the 2.13″ and 2.9″ WeAct Studio Epaper Modules available here: WeAct 2.9” 2.13″ 2.9 2.13 Inch Epaper Module E-paper E-Ink EInk Display Screen SPI Black-White Black-White-Red.

As I mention in the video I was having a hard time getting good solder joints from my Horusdy Soldering Station. This was annoying me so much that I went and purchased a new soldering iron! My new iron is an Metcal PS-900 Soldering Station and I love it! This is what a soldering iron should be!

We use the Arduino IDE and the sample code from WeAct Studio but we don’t successfully load content into our Epaper Module.

We use the Rigol MSO5074 Mixed Signal Oscilloscope to and the Rigol PLA2216 Logic Probe to wire up a Logic Analyzer to instrument out circuit, but we don’t follow through with that in the end. We run out of time. We will try again another day.
