After hours of try&error I found a good solution: Set up the FSPI and GDMA by using the regular C functions: ESP_ERROR_CHECK(spi_bus_initialize(SPI2_HOST, &buscfg, SPI_DMA_CH_AUTO)); ESP_ERROR_CHECK(spi_bus_add_device(SPI2_HOST, &devcfg, &spi)); Do a fake transmission to init all registers: ESP_ERRO...

Did you remember to de-reset and un-clockgate the peripheral first? If it's off, it won't do anything. Found a hint in ok-home 's link: REG_CLR_BIT(SYSTEM_PERIP_CLK_EN0_REG, SYSTEM_SPI2_CLK_EN); REG_SET_BIT(SYSTEM_PERIP_CLK_EN0_REG, SYSTEM_SPI2_CLK_EN); REG_SET_BIT(SYSTEM_PERIP_RST_EN0_REG, SYSTEM_...

Hello maybe this will help you https://github.com/ok-home/logic_analyzer/tree/master include/logic_analyzer_hal.h Gets samples into ESP32 buffer logic_analyzer_config_t - capture configuration start_logic_analyzer(logic_analyzer_config_t *config) - capture start void (*logic_analyzer_cb_t)(uint8_t ...

Did you remember to de-reset and un-clockgate the peripheral first? If it's off, it won't do anything. Thanks for the answer. For the clockgate I did REG_WRITE(SPI_CLK_GATE_REG(2), 7); After you sayed "de-reset" i searched for a way to do this, found only this: SPI_SOFT_RESET Software reset enable ...

Hi, I am new to the ESP32, but my first project already pushes this controller to its limits. The goal is to capture a very uncommon video signal on the FSPI port, and re-transmit it as a VGA-signal. The input signal have 3 wires: a combined SYNC signal and 2 Bit color (well, 4 shades of green...) s...
