Re: How can i support UART Tx with DMA(using UHCI driver api) and Rx without DMA(using UART driver api)?
Please, note that due a HW issue on UHCI of ESP32, RX transfer via DMA is not reliable.

Re: [Solved] Reading character input from the serial port
Hi all, to use functions like scanf, that are interrupt driven you should change the UART driver to interrupt driven mode, see https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/storage/vfs.html#standard-io-streams-stdin-stdout-stderr?. An example that does this is the uart_se...

hi,
you can enable ESP_CONSOLE_MULTIPLE_UART and select which UART you want to use for console.

Re: ESP32 Blinky on NuttX Port RTOS Apache
Is anything worth considering switching to from freertos yet? Nuttx Tizen-rt Zephyr Riot Hey, It mostly depends on your application needs. I'll let here a reading suggestion that compares Zephyr, NuttX and freeRTOS. https://micro-ros.github.io/docs/concepts/rtos/comparison/ It may help, but conside...

Re: using Arduino IDE SPI.h library with ESP32
Hi akshu15, I'll let here a link to a code that shows how to use SPI.h from the arduino IDE. In this code is shown also how to remap the MISO, MOSI and SCLK buses to other pins. One important point: Observe that when initialing the SPI instance, only MOSI, MISO and SCLK are passed as parameters to t...
