Quickie: Linux on the STM32F429 Discovery

For a while now, I’ve wanted to run Linux on an STM32F4, ever since I was working on CAPE. I knew about running Linux on the Discovery Boards that had an LCD Screen, but never bothered to pick one up … Continue reading

Driving a 7-segment Display with a Shift Register (74HC595)

I had a post a while back about driving a 7-segment display with an Arduino. Well, as you may recall, that took a lot of pins, 8 in fact. What if we could reduce that by 3? What if we … Continue reading

Reading analog values over I2C

So I’m back again with another I2C device made by NXP. My last one did I2C to SPI, but we’re here to do ADC. Now, if you’re the average Arduino user, then you have 6 ADC ports on your Uno, … Continue reading

Arduino I2C to SPI with SC18IS602B

I’m going to be doing some neat things with an STM32F030 and since it’s a limited pin number, I want to maximize my pins and I want to make it somewhat expandable\hackable, so because of this, almost everything is going … Continue reading

Seven Segment (Common ANODE) on Arduino

It feels like forever since I’ve posted! However, I have a very small post for beginners. We’re going to use an Arduino to drive a single digit seven segment display. Why something so simple? So this way we can build … Continue reading

Follow up to the Z08671-BASIC

Not too long ago, I talked about making a 6 chip basic computer with z8671. I did finally do a layout and I’m going to have the board made by JLCPCB to see how they are. I was recommended them … Continue reading
