Error -76 from MbedTLS
Hi everyone. Hopefully someone of you can help me in my current project. We are using ESP-IDF on the current stable version 4.0.1 with ESP-AZURE to send telemetry data to the Azure IoT Hub. I have my main loop which uses the light sleep mode and configured the wifi with power safe mode with the foll...

Re: ESP32 multiple SPI Max31865
But I've already registered more than 3 devices. Also its working on Arduino on the same esp32.

Re: ESP32 multiple SPI Max31865
Im registering more than one device to the bus.
When I am adding the 7th device, im getting the following error:
Error adding SPI device: ESP_ERR_NO_MEM
So my question is, is there a way to reduce the memory which is getting allocated by the devices?
Do I have any chance?

Re: ESP32 multiple SPI Max31865
So the Author of the library helped me out on that. Now its working on many devices but it always returns zero as resistance value. Is there a way to find out which PINS as MISO, MOSI and CLK I need to use? Do i need to use VSPI or HSPI? The problem is, that I did not connect the devices to the ESP,...

Re: ESP32 multiple SPI Max31865
Thanks for your fast response! My understanding of SPI isnt that big. Is there an example for the ESP32 on ESP-IDF which initiates more than one SPI Device? I do not need this library if I can easily poll the Resistance values, if easier. I nearly up to everything what helps to get this done. Could ...

ESP32 multiple SPI Max31865
Hey together, I really hope you can help me. I am developing software for an ESP32 DevKit V1. There are connected several Max31865 (exactly 8) to read data from the temperature sensor attached. I've to poll those values in a given time. So I've tried to use the following library: https://github.com/...
