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…
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 have lately purchased True Studio, so it was not a big surprice to see that True Studio now is merged with CubeMX. I am not a big fan of Eclipse based IDE’s, but this one is great for getting you project off ground fast. CubeMX saves you a few hours as you start the…
First draft of a new SWD adapter designed to be installed/removed while the Hat is inside the stack. SWD on this will work even if you miss a row while connecting because Reset is pushed to 3.3V and all other signals are duplicated on both rows.I will make another using ST-Link V2 connector directly. Currently…
J7 above is the USB connector on my Hat’s and 44/45 at right is the connection to the MCU. This is all you need to do to have a working USB connected to an STM32. Software is even easier if you just want a serial port. You just install STM32 Virtual Serial port driver for…
SW4STM32 allows you to maintain multiple projects and have multiple ST-Links active at once. This is a welcome feature as I now need to program several at once to get backbone SPI working. I finally got the 10x USB cables, so everything is set up and working. This also means that I start using SW4STM32…
Reading up on these machines I find a lot of praises about this series. I really like this machine with 58 feeders, but it will cost me close to 6000.- USD before I have it in Norway. The reviews are all good. The main comment is on camera lighting. It can detect 0603 components, but…
I don’t have the answer to this riddle yet, but I am searching for a more structured way of doing this blog that don’t involve myself digging into web development. I simply don’t have the time (or skills), so I am depending on either someone else assisting or finding a plug & play solution. At…
One of the ideas I am playing around with is to make my own programmable DC/DC PSU based on a MCU. The technique is very similar to a driver channel on a motor by generating a PWM signal. To get a DC out you add filter(s). If you have 48V and 50% PWM duty the…
