adc_block_ram_spi_top

Xilinx Artix-7 FPGA design using block ram, XADC and a SPI slave (SCARF). The block ram is dual port and can be written by either SPI or XADC samples, and only read by SPI.

arduino_dac

Arduino library DAC control using a serial (USB) terminal

bk5491b

Python class to control BK Precision Bench Multimeter BK5491B

bk8500_python

Simple Python driver for enabling a CC mode load.

blink_stm32f411_uf2

Arduino Blink made into a UF2 for STM32F411 Blackpill. First, tinyuf2 for Blackpill needs to be flashed as the bootloader. This UF2 file can then be copied to the MCU.

bq25898d

Python Class for controlling the BQ25898D

button_press_uart

This FPGA configuration measures the "round trip" latency from when the FPGA sends a UART byte to the host and a host response is received by the FPGA.

cmod_a7-uart_block_ram

The FT2232H on the CMOD-A7 is used to drive UART data to read/write to a register map implemented in block ram.

This is a demonstration of UART communication using the FT2232 on the Cmod-a7 FPGA board. The TX and RX are passed through the FPGA to board pins, which then connect to my Raspberry Pi. Bi-directional communication is demonstrated in Python.

cmod_a7_pattern_generator_v1

cmod_a7_spi_sram

SPI slave to External SRAM interface for Cmod A7

dac63204evm

Python control of DAC63204EVM board which uses FT4222. I2C, SPI and GPIO functions are included. DAC63204, DAC53204 and DAC43204 parts supported.

gd25q16c

Python driver for GD25Q16C 2MB SPI Flash Memory IC

gd25q16c_ft4222

GigaDevice GD25Q16C 2MB Python memory driver for FT4222 USB to SPI bride. Quad and Dual width demonstrated

gd25q32c

Python driver for GD25Q32C 4MB SPI NOR Flash Memory IC.

get_instrument_dict

Python script that returns a dictionary of all SCPI instruments detected

hmp4040

Rohde & Schwarz HMP4040 Power Supply Python control

i2c_slave_fpga

Systemverilog implementation of an I2C slave with a simple register map. Multi-byte reads and writes supported with address auto-increment.

ina219

INA219 Log Battery Voltage and Charge Current to file

ina260

Texas Instruments INA260 Python driver

ina260_logfile_micropython

INA260 logging to screen and logfile, implemented in MicroPython (using Adafruit QT PY RP2040)

inst_settings_in_image

This is a collection of methods to query lab instrument settings and save them in a PNG image file. The file can be used later to restore all the lab instrument settings.
