Some thoughts about embedded development. In specific, about source code licenses. And the reason why I started this PSoC4 support for libopencm3 project. The first reason to start the project is, right now, the only way to develop for the PSoC4 is through PSoC Creator, which only runs on Microsoft Windows. As I don’t use…
Intermezzo: looking at the ROMTABLE
Looking through the psoc4 implementation in openocd I noticed a function called psoc4_get_family(). In this function, reads some data from the ROMTABLE, deriving a family and designer from the data available there. Now, this ROMTABLE is documented in the various register TRMs, and it is a part of the CoreSight specifications. This is the information…
Clocking the PSoC4
After getting a blinky program to work on both the PSoC4200 and the PSoC4200M series (the code is the same), I wanted to continue with some communication. For this purpose I took a look at the Serial Communication Block (SCB) peripheral. An SCB can do either UART, SPI or I²C. After looking at the registers,…
PSoC4 support for libopencm3, the first steps
As I’ve discussed before, I’ve started a project to implement support for the Cypress PSoC 4 series, so they can be used without PSoC Creator, which only runs on Microsoft Windows. I am doing this so I can develop for the PSoC 4 on a linux machine using only an open source toolchain. As the…
I’ve been busy
As you see, there is something on this website now. Basically just the theme and the menu, but I’ve been busy. I’ve been reading datasheets and technical reference manuals. SO, guess what I’ve been doing? I’ve been working on implementing PSoC4 support into libopencm3. Why? The PSoC4 is a nice microcontroller (and cheap, the manufacturer…
Welcome
Welcome to BlaatSchaap 😉 After many years of doing nothing with this domain (apart from email) I’ve decided to start using this website for some of my embedded projects. Some time next year I’ll be posting stuff on here, for now, happy holidays!
