0x3c is decimal 60.

If you want to use two of these displays on the same i2c bus, check if the oled module has any address select resistors on the back.

To stop the client browser from making subsequent requests, add some cache headers to your large static scripts

@seonr aka Unexpected Maker is making a ESP32-S2 ProS2 dev board. That's the hardware side covered. Not sure about software side.

You can base64 encode an image and embed it in the html. Saves multiple http requests.
Still need a http server to send the html to a browser.

Which web server did you try, which was considered too heavy?
We might be able to suggest some alternatives.

I can replicate the problem now. It seems I'm missing these PPL3 defines (lifted from NUCLEO_H743ZI/mpconfigboard.h) // The USB clock is set using PLL3 #define MICROPY_HW_CLK_PLL3M (4) #define MICROPY_HW_CLK_PLL3N (120) #define MICROPY_HW_CLK_PLL3P (2) #define MICROPY_HW_CLK_PLL3Q (5) #define MICROP...

It builds fine for me on the latest (head) version. Maybe try recompiling the cross compiler?

I have a bunch of old chips to test against: EEPROM AT24C01A 1K I2C DIP8 AT24C02N 2K I2C DIP8 AT24C04A 4K I2C DIP8 AT24C08 8K I2C DIP8 AT24C16 16K I2C DIP8 AT24C32A 32K I2C DIP8 AT24C64N 64K I2C DIP8 AT24C128 128K I2C DIP8 AT24C256 256K I2C DIP8 ST24C16CB1 16K I2C DIP8 24LC512 512K I2C DIP8 P24C256 ...

Hi @Sniper. Is this necessary in the code? import machine and import time, import Pin? Unless your boot.py or main.py imports machine, you'll need to do it before you can use it. Otherwise you'll get a NameError. import time lets you use time.sleep() . Without it, time won't exist (in the variable s...

Hi @Sniper There are many different dev boards which use the STM32F4xx series cpus. They each share the same pins for analog, digital, PWM, UART, I2C, SPI etc. If you can find similar boards with better documentation, some of the info may still be relevant. All of the pins support digital IO, and so...
