Hi :)

I'm currently working on a little project that uses 4 LCDs (st7735 controller). They are connected as followed:
Mosi=4 , SCK=14 , A0 = 5 , CS1=2 , CS2= 26, CS3= 25, CS4= 32

Problem: Only CS1 (GPIO2) will work. All other CS stay low. I can't think of any reason why :cry:

This is my code. I ...

Any ideas?

Hi :)

is there a way to set the counter of the hardware timer to a specific value during runtime? I would need it to synchronize two devices, that are sending messages over RF.

Why?:
Both of the devices have a internal timer running. It creates time-slices, that tell the devices when to send and ...

Hi ESP_Sprite,

thanks for the fast answer. You're right, this caused the triggering of the interrupt watchdog :oops: . So now I'm using the xTaskNotifyfromISR() function to unblock my handler task. Here's my current code:

#include <stdio.h>
#include "esp_types.h"
#include "freertos/FreeRTOS.h ...

Hi,

I'm having some problems with the RX of the Uart.

What i want to do: I want to detect a series of five 0x55 on a RS485-bus and trigger an interrupt. My data packets for testing look like this:
0x55|0x55|0x55|0x55|0x55|0x10|0x20|0x30|0x40|0xFF

My little test project:
#include "CT10 ...

Hello ESP_Sprite,

thanks for your help and your really good explanations. I didn't pay attention to the static variable being used multiple times, as soon as using multiple timers. Now it's totally clear for me :oops: .

So I corrected my code and everything works fine :)

#include "HW_Timers2.h ...

Hi guys,

this is my first post here. So if I'm in the wrong topic or anything else feel free to correct me ;) .

Normally I am working with Atmel Xmega controllers, but as soon as i discovered the ESP32 I fell in love with it :D . So here I am, trying to understand FreeRtos and the ESP-IDF API ...
