Linux started seeing a serious increased usage in embedded projects with raspberry PI due to it’s availability and low cost. And the last years have provided a large number of low cost embedded Linux solutions. They are getting smaller, more powerfully and decreasing in cost making them very attractive in projects. Raspberry PI might still…
I have struggled a little to find an IDE I was OK with, but finally settled with STCubeIDE or Eclipse as it actually is. This is IMO one of the smarter moves that ST have done to support their MCU’s. The editor is “ok”, it compiles, download allow you to debug multiple targets + I…
DSO150 is very easy to use and operate like a multi-meter, and this caught my attention because the other Oscilloscopes I havve needs to be set up. DSO150 is basically only to switch on and use like a Multi-meter – you instantly see the signal and it was surprisingly easy to operate the HMI. I…
This Oscilloscope took me by surprise. I ordered it mostly for fun, but it turns out to be very functional and easy to operate Scope in a multi-meter format. 200Khz actually cover a lot of the activities I do and by attaching a battery you get a very handy, single channel Oscilloscope in a handy…
I accidentally came across “Rock PI 4 b” and first believed it was about Raspberry PI 4 as I realized this is a board based on Rockchip RK3399. It is very similar to Raspberry PI 4, but contain some very interesting differences. Of most interest for me is that the form factor and GPIO pin…
Quad core 64 bit Cortex A72 1.5 Ghz 2 x 4K HDMI ports USB 3 Gigabit Ethernet Up to 4GB RAM and more Priced at 35$ for 1GB and 55$ for 4Gb this starts to look like a serious challenge for more classic desktop computers. I tried to buy one, but getting the “sold-out” from…
I am using 2 x XPortHub cards called Left and Right in the debug config. The picture show both cards being debugged in single step at the same time – I am impressed! This was exactly what I needed right now. The only trick is to start the GDB server on different TCP ports +…
ST recently acquired Atollic TrueStudio and merget it with CubeMX into STCubeIDE. Having searched for a proper IDE to use I must admit this one actually do the job nicely. To start a project you use CobeMX now integrated into the IDE, make your selection and as soon as you switch to code it is…
First attempt on block diagram for the 3D Sensor Hat. The main components are FXOS8700 (Accelerometer and Magnetometer), FXAS21002 (Gyroscope), NEO 6/7/8 (GPS) and BME280 (Temperature, Humidity and Pressure). I am also attempting a TFT connection here, but this is secondary and can be ditched if needed. The rest is classic – Raspberry PI/SPI on…
Final 3D of the Sensor Hat. The most noticeable here is that I start using the 2×5 pin SWD header. The rest is as described before. MCU STM32F405RG 1 x High Speed SPI for backbone Raspberry PI Hat format 1 x CAN for control bus. 8 x 2 x Analogue/Digital IO Signals. 3 x I2C…
