STM32H503CB is fastly turning into my favorite MCU for three reasons – it is fast, it is low cost and it has en extremely good IO routing system. It’s only drawback is 128Kb Flash and 32Kb SRAM, but it exist other MCU’s in the same series with more (that also cost more). That said it…
One of my concerns on 600V design is how to make ADC readings in the 600V area. I need 3 x Current sensors, 1 x DC Voltage Sensor and 1(2) x Temperature sensors in addition to support for up to 3 resolver sensors as well as an external motor temperature sensor. That sums up to…
This MCU started to interest me because it is a low price alternative with a lot of contents. ST’s price is 1.7 USD, but that is 3++ USD through Digikey in low volume. It is a 128Kb Flash version, but it has a promissing build-in Bootloader that I want to experiment with. If you build…
I am used to problems with STM32CubeIDE – this one popped up as I wanted to open the ioc file of a STM32H503RB – it is a well know error from Eclipse based tools – or more correctly Java based tools. You can always recognize Java since the code is slow as a slug and…
I created the footprint for GX16-8 and updated the 3D with a few details. I will see if I can add the thread as well. I quite like these connectors, but I am a bit concerned that I only find them on one source on Aliexpress + I realized that these connectors have a different…
I will upload these packages on github (here) because it is 2 days wasted work having to draw them and I depend on others publishing their 3D packages myself. Just be aware that these are Beta – their accuracy is subject for testing. I will draw the last five as I get them. Have fun.…
I fancied using GX16 connectors in a project since they are low cost, robust and can be made water proof. I found 2,3,4,5,6,7,8,9,10 and 12 pin versions with bend pins so they can be mounted directly on a PCB and fixed to a panel. But, what I did not find was 3D models for KiCAD,…
CH32V307 is a RISC-V based MCU that is created by WCH and that got my attention due to it’s low cost – 3.- USD in quantity 1 and down to 1.9 USD from JLCPCB. I have read about RISC-V as an alternative to ARM for years, but I have not paid much attention to it…
It is two controls with an identical border on the picture above. The button display the border correctly, while the ComboBox do not display the border at all. It does have a BorderBrush that I set, but it has no effect. This is quite common with build in native controls – it might be a…
And this is the result of the code generator. In C++ and C# you can use inheritance – simply use a base class for symbols, autogenerate a HMIButton_base and then create the final HMIButton manually – this is a nice way to allow autogenerated code while you still have the full manual control. C# have…
