Hi, Im trying to stream bus data from another microcontroller to the esp32 per I2C. The ESP32 is the I2C master. Problem is, there appear delays in longer telegrams in the I2C stream, the esp32 seems to have issues with it. 2023-07-20 20_51_25-PicoScope 6.png Im not exactly sure why that is, but the...

No Answer?

Hi, I used a J-Link Plus for ESP32 debugging so far, and it was working, but I had two issues with it: 1. The necessary WinUSB driver did get corrupted by Windows(10) every now and then, making it necessary to run Zadig again, which needs admin rights also... 2. In Visual Studio Code, debugging work...

xtensa-esp32-elf-gdb.exe cannot be Run
after Update to ESP V51RC1 And downloading ESP-Tools - xtensa-esp-elf-gdb 12.1_20221002

What should I do?

Oh!
Thank you.
Really glad I asked

Hi, I'm trying to implement a custom SPI Bus-System. I'm short on IO's, so I'm trying to have a virtual CS pin. My idea is, clock is in high impedance normally. Each sender has their own send Line / MISO / MOSI One bususer, has the task to cyclically send a 1 byte token. This one Byte token is a add...

How can I call the ISR processing faster?

@MicroController: Thank you for the Input :) my current issue: ISR: static uint32_t UART_ISR_ATTR uart_tx_write_fifo(uart_port_t uart_num, const uint8_t *pbuf, uint32_t len) { uint32_t sent_len = 0; UART_ENTER_CRITICAL_SAFE(&(uart_context[uart_num].spinlock)); uart_hal_write_txfifo(&(uart_context[ua...

Sadly no one answered, but I figured it out somehow. Heres my solution: #include "uartTransfer.h" #include "main.h" #include "esp_event.h" #include "esp_log.h" #include "driver/uart.h" #include "driver/gpio.h" // Interrupt manuell #include "FreeRTOS.h" #include "freertos/task.h" #include "freertos/q...

how to figure out the actual lenght of format, but I later figured out myself:

so we can just use va_list arg_list...
