Hi Martin,

Thanks for your efforts. Have you tried the same GPIOs I've used? If I use software mode all works fine with the slave address 0x88 I am using.

Hi Martin,

Thanks for your lines. The speed is set back to 100KHz, I was trying different speeds to see if there would be any difference, but same issue.

I've also added a loop at the end and just tested the lst program on hardware, confirmed the same issue I'm afraid

Cheers

The 2 sample programs attached

Hi all. Found a bug with the I2C Master Component on ESP32, I wonder if you can help me please. Simple program attached. Works fine in Software mode target slave address is 0x88 (note the time base on the scope is 5ms per divison = THIS IS WEIRD, it's way too slow) Now same component also at 100KHz,...

Hi there,

Are ESP32-S2 and ESP32-S2-H4 supported with Flowcode?

Thanks for the insight,
R

Just beware some ports have got pullup/pulldown resistors and as Leigh mentioned are special ones, so avoid using those. An excellent reference I found whilst having similar issues here, have a check and take note of each and every I/O pin: https://randomnerdtutorials.com/esp32-pinout-reference-gpio...

Hi Martin,

Thanksw for the swift reply and fix. It works perfectly well now

Many thanks again, enjoy the rest of the weekend.

Hi all, Would it be possible to get a copy of the SSD1306 I2C Component code to adapt it to 128x32 pixels? We are using a 0.91" OLED 128x32 pixels with SSD1306 controller in I2C mode. When I configure the component to be 128x32 pixels the program does not compile and throws an error. Changed back to...

Thanks for this, OK that explains it! The period cannot be set to 1000, it's strange as that's the setting there on the menu when on milliseconds... :evil: And the integer has to be smaller than 256 ;-) So all fine now, that makes sense. It's not as flexible as the PICs, but very simple to use! :-) ...

Hi guys, I've been using Flowcode for a very long time, always with PIC16/18/32. It has always been very straightforward to make an LED blink every second from within an interrupt for testing... However I'm trying ESP32 and need some help with interrupts as can't get this to work at all :?: I've ena...
