Trekulator: A Reproduction Of The 1977 Star Trek Themed Calculator
I have a new post on Hackaday: Trekulator: A Reproduction Of The 1977 Star Trek Themed Calculator.
AVR128DA48 Curiosity Nano evaluation kit
These AVR128DA48 Curiosity Nano evaluation kits look kinda cool. I think I will get a few to play with. The debugging chip on them should work with the MPLAB X IDE I believe.
Microchip PIC & AVR Examples
Microchip has a bunch of helpful code samples over on github: Microchip PIC & AVR Examples. 745 repositories! Oof.
Ten cent micro
I watched this fun video about how to use a ten cent microcontroller:
How To Easily Program The ATtiny85
This is a note for Future John. I found this no-nonsense video about how to program the ATtiny85 using an Arduino: How To Easily Program The Attiny85
MilliForth-6502, A Forth For The 6502 CPU
I have a new post on Hackaday: MilliForth-6502, A Forth For The 6502 CPU.
Some material was deleted by the editors so I have included it below for the archive.
The main code is the assembly code in sector-6502.s.
These are the commands I ran to take it all for a spin:
mkdir /tmp/milliForth-6502 cd /tmp/milliForth-6502 git clone https://github.com/cc65/cc65 cd cc65 make sudo make install cd .. git clone https://github.com/ShonFrazier/lib6502 cd lib6502 make sudo make install cd .. git clone https://github.com/agsb/milliForth-6502 cd milliForth-6502 touch out source do1 sector-6502 wc -c sector-6502.out hd sector-6502.out
Building A Custom Zynq-7000 SoC Development Board From The Ground Up
I have a new post on Hackaday: Building A Custom Zynq-7000 SoC Development Board From The Ground Up.
The presenter starts by designing the power system, then makes progress on power, improves the schematic, integrates DDR RAM, adds USB PHY, Ethernet PHY, and SD card, starts on HDMI, makes progress on layout, makes progress on routing, continues with routing, configures with Vivado and estimates costs, receives PCBs and components, starts the PCB assembly, adds power rail components, adds core components, connects power and does initial programming, makes an LED blink, gets the ARM APU working, troubleshoots FT2232H to JTAG, resolves FT2232H to JTAG issue, adds UART and DDR, gets HDMI working, installs PetaLinux, and at long last configures USB and Ethernet in PetaLinux.
See AMD Zynq 7000 SoCs for specs from AMD. The executive summary is that this SoC includes an ARM Cortex-A9 Based APU and an Artix-7 FPGA (or a Kintex-7 FPGA on higher models). We suppose this is an opportune time to mention that in case you missed it Xilinx was recently acquired by AMD which is why you see the AMD branding now.
Summarizing references from these videos, other videos include What your Differential Pairs Wish You Knew and How to Achieve Proper Grounding by [Rick Hartley]; books referenced include Printed Circuits Handbook 7ed and Signal and Power Integrity Simplified 3ed; courses referenced include Mixed-Signal Hardware Design with KiCad and Advanced Digital Hardware Design from [Philip Salmony]; and software used includes EasyEDA, Vivado, Vitis IDE, and Tera Term.
