SPI with DMA on external pins on lyrat 4.3

Postby benbiles » Thu Jan 09, 2020 2:31 pm

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 program the device ! I'm using the I2S pins ( connected to Codec ) I2C pins connected to codec.

GPIO15 TDO
GPIO13 TCK
GPIO12 TDI
GPIO14 ?

Theres some 4.7k pull up / pull down resistors I'd have to take off I suppose !
