# Trilby HAT ECP5 FPGA SDR for Raspberry Pi http://www.kinetic.co.uk/Trilby.php This is my attempt at using open source tools to generate bitstream Run `make prog` to load the example to the board. ## enable RTC Add to config.txt: ``` dtoverlay=i2c-rtc,ds1307 ``` or execute in shell: ``` echo ds1307 0x68 > /sys/class/i2c-adapter/i2c-1/new_device ``` ## read HAT ID eeprom Add to config.txt: ``` dtoverlay=i2c-gpio,i2c_gpio_sda=0,i2c_gpio_scl=1,bus=4 ```
