I was rather pleased with routing MC3P60V because it is a dense, functional design. But, as I reviewed the design I found this. The error here is that this is 60V and I used 0603 packages. 0603 usually hold 6ich V, so I will either need to upgrade to larger 60V or try something else.…
I am a big fan of things that just work, which is why I have stuck to Coocox and CoIDE for years. But, as it now looks like this tool is dead I basically need to move on. Coocox had a very good concept and was one of the few Eclipse based IDE’s I liked,…
I have a load of motor controllers that I want to continue on, but to focus on the more advanced ones. MC4X60V50A This is an early draft of rev 1.1 of the MC4X controller. Notice the heavy wiring at right to support 50A + all components top-side so I can add heat-sink on the PCB.…
I finally got revision 1.1 of these boards yesterday, so I can get on with this adapter. The main error on 1.1 was lack of crystal and I realized I needed the crystal for USB as I tested. I like CubeMX, but I fail to undestand “designers” that want to create a “HAL” and only…
The config system in CubeMX allows you to configure and generate code for all components you have included, including FreeRTOS and libraries. This page show the config for FreeRTOS and it allows you to create a list of Tasks as well as message queues. The folders on top are Config Parameters Include Parameters User Constants…
This shows the STM32CubeMX for my 3 x RS-X PLC Module. I find this tool to be quite usefully as it allow you to set up the clock, configure each function and wire the MCU. It also generate a nice PDF document with all details as well as a starting project with all init code…
Been a lot of motor controllers lately so I finally decided to assemble part of my PLC system. What you see here is the motherboard with a simple RS-X module connected. Not all components are assembled yet, but processor is alive. This board have 3 x fully galvanic isolated RS485 circuits and a 2 x…
Investigating the issue one option is that what snapped the TSP54060’s is that my PCB tracks are to close for 60V. You need close to 3000V per cm to create an arch and that is 30V per 0.1mm. I can’t see a weak point, but those pins are 0.2mm apart. A bit of extra solder…
I received the MC3X60 Motor controller PCB’s yesterday and as always it is awesome to see how small my designs are. As this is the first time I use TSP54x60 I instantly assembled this to test and was pleased to see 3.4V out. This circuit worked well giving 3.4V out with input from 12 to…
Every year around christmas I tell myself that next year I will have electronic christmas decorations, and as next year arrive it’s forgotten until it’s to late. A combination of STM32F030 and ULN2003 is excellent for a very small x-mas tree PCB with blinking LEDS and home made tree lights. In fact I have done…
