Q: How much flash memory is on the board?

Preguntado por fabelizer sobre 2020-03-02 05:49:12

nooitgp AllESP32 boards have standard 4Mb flash-memory, divided in several partitions. There are some with more than 4Mb, but these are very rare.

fabelizer This worked for me, but only on 1 of my 2 boards. The board that does not work must have a faulty display, as all indications are that the programming and ESP32 are fine. However, the display did work when it arrived on the demo code...sure wish I could get a copy of that demo source code!!

Works. I've read some overcomplicated about the display. I got it to work with U8g2lib. I used the following constructor line: U8G2_SSD1306_128X64_NONAME_F_HW_I2C u8g2(U8G2_R0, /* reset=*/ U8X8_PIN_NONE, /* clock=*/ 16, /* data=*/ 17); this has to be changed to the right pins so it becomes: U8G2_SSD1306_128X64_NONAME_F_HW_I2C u8g2(U8G2_R0, /* reset=*/ 16, /* clock=*/ 15, /* data=*/ 4); This got it working for me with the usual U8g2lib functions.
