I am totally stumped as to how to track this down. The only time it happens is when I save a value every 30 seconds using preferences.h. void dothis(double value) { // Save the odometer value using Preferences preferences.begin("gps", false); // Open preferences in read-write mode preferences.putDou...

At the very least I am sending the letter "C" from the Teensy to the ESP-wroom-32. ESP says its receiving a null. I'm stumped. The reason for the 2 sec delay on the esp32, I was just trying to see if it recognized the pin being flipped from low to high on each side (it does). Teensy code: #include <...

Well, I reverted back to the ESP32CAN library: https://github.com/sdp8483/ESP32-Arduino-CAN there is still a delay. I updated the miwagner to work at 1000mbits but it also has the same issue. I am stumped as to where to debug. I'm experimenting with TWAI_MODE_LISTEN_ONLY but when I do that I receive...

Ok, so I went back to the miwagner version of the library and got it working at 1mbit. Messed with recieve buffers and it made a difference. Now I'm wondering where to update the rx_buffer on the new library that I referenced earlier...

So I havent made any changes other than... as far as CPU speed, it should be 240mhz. I'm using PlatformIO and VSCode so I think by default when I selected the esp32 it had 240mhz setup. When you're talking about IRAM, is it as simple as me adding IRAM_ATTR to my parsing logic? or do I need to do tha...

I'm using this library on an esp32 wroom32d, 8mb. https://github.com/sdp8483/ESP32-Arduino-CAN I'm using it at 1mbit, and converting data to display on an LCD. Some data comes in quicker than others but it still feels like there is lag there compared to 500k. My code in loop() if (ESP32CAN_OK == ESP...

Running an ESP32-WROOM32D..

using the ESP32CAN lib :

https://github.com/miwagner/ESP32-Arduino-CAN

When I set to 1000K its actually 500k.

Is this the correct brp_div to clear? or how to I make this thing work?

MODULE_CAN->IER.U &= ~(1 << 5); // Clear the BRP_DIV bit

Are you suggesting that library works properly and can communicate at 1K?

I'm using an ESP32-WROOM-32D connected to an ECC508A via SDA and SCL. Both have 4.7k resistors. I checked the voltage at the ECC508A and I'm getting a solid 3.22v. What I'm doing is storing a key in slot 0 on my test board but when I try to read it I get this error: [ 2188][E][Wire.cpp:513] requestF...

I've written code and want to keep it from being installed on other ESP32's when I release firmware updates. I use VSCode and PlatformIO, Debian 11. I read that I need to enable secure boot, sign my code and all that stuff. Followed this to install espidf, so I did this: https://docs.espressif.com/p...
