Permal, thanks for the reply and pointing to your repo!

The first thing I notice is you use much weaker pull-up than I. You have 50K on your board and your software also enables the internal pull-up which from https://esp32.com/viewtopic.php?t=5111 we should consider is also 50K. So effectively you ...

I am having a tough time getting the sd card example or my own code working reliably.

The 2 dev boards I am using (DOIT ESP32 DevKit) I have
- used espefuse to set them for 3.3V flash so that GPIO 12 is not an issue for boot.
- jumpered GPIO 0 and GPIO 2 to ensure at boot GPIO 2 is low
- I have ...

Here is an aspect others have not pointed out. Arduino effectively hides you from project structure and build process. Arduino gives you the editor and a menu stucture to build the code and upload it to the MCU.

The IDF you can pick what editor you want (I use eclipse) , you can use c or c++ and ...

Hello,

Before I start to rework an Arduino library or roll my own for the IDF I thought I would see if anyone has one already created?

Thanks, Jeff

By accident I have it working better. All I did was change the logging. I removed all logging from the code except for

ESP_LOGI(TAG, "[UART PATTERN DETECTED] pos: %d, buffered size: %d", pos, buffered_size);

Now things work fine. It seems my previous experience has to do with logging output to ...

Hello,

I am parsing GPS NMEA data inbound on UART2 at 115200 baud. The GPS is capable of 50Hz updates though I have it set to 25Hz currently. Module does not have any flow control, it just streams the NMEA sentences.

I am using current master of IDF from git and planned to use uart_enable_pattern ...

Here I am replying to my own post again. So even the new card I got to work for 1 set of tests is no longer working. I have moved to just using the IDF unit test app to test. I have 3 SD Cards and 2 different SDCard slots connected.

Probe for 4-bit and 1-bit work fine and get card details correctly ...

You can include the Arduino system as a component to your IDF project
https://github.com/espressif/arduino-es ... mponent.md

It allows you to use IDF and Arduino together

Seems I got the IDF version of the code working. How? I changed the card brand and type. My initial tests were with a SanDisk Ultra 32GB card. It formated using Windows SD Formater utility and ran under Windows, Android phone etc fine. I could create files using Arduino.

I had thought maybe it was ...

Hello,

I am trying to add some SD Card capabilities to a project and recently tried the example that comes with the IDF (update to date MASTER IDF). No matter what I did I couldn't get it to work.

I (0) cpu_start: Starting scheduler on APP CPU.
I (259) example: Initializing SD card
I (259 ...
