HiLetgo 1.3" SPI 128x64 SSH1106 OLED LCD Display LCD Module for Arduino AVR STM32

The I2C build of this display would not play nice with the faster MCU and the MLX90614 IR sensor. I used the u8x8 version of the olikraus/u8g2 and the Adafruit MLX90614 libraries. Wiring instructions from another review of this device helped me connect it to the MCU. U8X8_SH1106_128X64_NONAME_4W_HW_SPI u8x8(/* cs=*/ 10, /* dc=*/ 9, /* reset=*/ 8) is the correct declaration for the olikraus library. I used the u8x8_font_victoriabold8_r font to give a display area of 17x8 characters.I would buy this again as needed.

At first nothing would display. Thought it was bad. Then found out it doesn't work with basic library settings. Used the U8glib as suggested here in other reviews. That got the display working, but was not compatible with the sketch I was using. It would not work well with Adafruit_GFX.h. After some Googling, found that this display will work with Adafruit_SH110X.h by using the lines below to define the pins for SPI. Works great now.#define OLED_MOSI 11#define OLED_CLK 13#define OLED_DC 9#define OLED_CS 10#define OLED_RST 8//Adafruit_SH110X display(OLED_RESET);Adafruit_SH1106G display = Adafruit_SH1106G(128, 64,OLED_MOSI, OLED_CLK, OLED_DC, OLED_RST, OLED_CS);

These are great little screens. I experienced some variation in screen glass defects in mine. Most were perfect, but all lit up and worked perfectly.I wanted to share that a critical difference (for my purposes) between these (SSH1106) and the SSD1306 chip is that the SSH1106 chip does NOT offer a horizontal addressing mode with automatically-advanced page/column pointers. This means that you won't be able to take full advantage of DMA since the page pointer needs to be manually advanced by your software. It's not the end of the world, but means more interrupts and code leverage the DMA.Most of the commands are the same between them which is why this screen will work with an SSD1306 library, but I spent forever figuring out why I could not get it to display correctly using DMA. I had the wrong data sheet and this chip only offers page addressing.If you don't care about such details, this is still a perfectly good option. I just wish these were as cheap as they used to be....

Used to replace 0.96". Not much bigger, but seems much bigger. Far more visible and practical. Nicely made. No issues with getting it to work with an RPi Zero and a 3B+. Had been using adafruit ssd1306 driver, but switched to luma.oled as this one is sh1106. I like luma.oled much better, even for 1306. Photo shows it with a small bezel I printed for it. It'll all soon get packaged in a printed case with the 3B+ and a GPS receiver. Glad I found it. I'm going to order a couple more.

Monochrome, but worthwhile for small diagnostic and informational displays. The mounting holes are positioned to make mounting actually possible without destroying the display. Fast update, plenty bright. I'll use these until I need color, then switch to the slightly more expensive color displays.

Worked as expected using the U8G2lib and the SH1106 construct. Used it to display NEO 7 GPS NMEA serial messages and it worked great. Save some time and use the construct below with an arduino board. It took me a few tries and some online research to get it to display data.U8G2_SH1106_128X64_NONAME_1_4W_SW_SPI

Price is right and it works well. Even brightness and no dead pixels. Using U8g2 with Arduino (teensy) everything works as expected. It came in a plastic bag which was placed in a padded envelope. Surprised it survived.

Only worked for a week. Had 2 dead pixels
