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…
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…
Half Duplex SPI allows all units to send to each other using MISO or MOSI. The challenge is that if 2 units try sending one might pull high and another low so you get a short-cut. The same goes if more than one tries to become Master and run the clock. The diagram above solves…
Doing a review of your Jown work is a bit of a challenge, but it is possible. The trick I use it to complete the work and then let it rest 1-2 weeks before I pick it up and update documentation. This technique has in the past proven quite efficient, but I would recommend using…
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…
