Re: lyrat 4.3 schematic

OK, thanks. I'll stick to using the SDCARD IO pins as I might need JTAG debugger

lyrat 4.3 schematic

does anyone know what the pins are used for on lyrat 4.3? Are they unconnected because they are 1.8v only ? SPI_SD0 SPI_SD1 SPI_SD2 SPI_SD3 SPI_CMD SPI_CLK the TF_CARD uses these pins shared with JTAG connector IO15 IO14 SD_IO13 SD_IO12 IO4 IO2 IO34 I removed the SD card and removed the 10k pullups ...

Re: ESP32-Lyrat SPI connections

Hi Chris,

I just wondered if you had any luck getting SPI working over JTAG pins ?
Did you have enough for CS pin to ?

Re: which GPIO pins for SPI with DMA on lyrat 4.3

ok great , I'm pretty sure I can get away with less than 20mhz SPI as long as I can get DMA working so I'll try to use the multiplexer and repurpose the JTAG pins on the lyrat 4.3 board. no idea yet where the JTAG GPIO pins are defined in esp-adf but should be able to find them. hopefully I'll have ...

SPI with DMA on external pins on lyrat 4.3

SPI with DMA on external pins on lyrat 4.3 , does anyone have a code example for esp-adf / esp-idf ? is it possible ? in the SPI master example the pins are already used for I2c and I2S on the lyrat 4.3 can I just say re-assign the JTAG pins to SPI since I'm not using them ? UART pins are needed to ...

which GPIO pins for SPI with DMA on lyrat 4.3

Hi, I'd like to setup a SPI device located on external pins on Lyrat 4.3 dev board using DMA transfer. so , 2 questions ! 1/ is there DMA mapping on the ESP32 module for SPI ( only certain GPIO pins available for DMA / SPI ? ) 2/ what pins are best to use ? the I2S pins are connected to the Codec IC...

Re: applying esp-dsp IIR biquad to pipeline or element ?

fully working in Stereo !!!! :D :D :D :D The hardware was fine , you were correct , i needed to de-interleave I2S int16-t to float -> de-interleave -> DSP L & DSP R -> float to int16_t -> re-interleave !!! I untangled the code from equaliser.c so its own thing and called is dsprunner.c awesome , sup...

Re: Updating lyrat 4 3 firmware

OK scrap that question.

I'm using EPS-IDF and ESP-ADF so not relevant.
Also hardware is not broken !
