Just watched a 2 hour video on How to achieve proper grounding in PC Boards by Rick Hartley

The energy in a pcb flows in the dielectric NOT the traces !!!!!

I thoroughly recommend it.

Am a regular importer from china and now almost all the prices gone up around 30 to 40% and few items more than double the price... Those who said 100KK stock available are telling all sold out. Definitely goinf to be very tough... The  shortage impact has not yet started to reflect the local market fully. Once it gets reflected there will be no stock available anywhere... Very bad situation. And few companies declare it will not come back to normal tjis year 2021. Not sure to take how serious this will be..

And on top of all. Chinese new year is around the corner. Factories in China will close down for a month. Also in Taiwan factories will close, but not quite as long as a month

Honda are closing plants because of the shortage
Most of them are in some way touched by the semiconductor shortage

 This time looks serious. Big companies plan to increase the prices with 20 to 30 percent and this will be seen in the market very soon. And this is not just a rumor. A big company known by more than  95% of the forum's users have some internally anouncment. Unfortunatelly can't reveal the name but is good if have large production to make an early purchasing.

for STM32F042 based hardware ( CANtact, CANable, Entreé ) - 1 channel ( acts as PCAN USB ):
https://github.com/moonglow/pcan_cantact

for STM32F407/405 dev boards - 1/2 channel ( acts as PCAN PRO/PCAN PRO FD/PCAN FD ):
https://github.com/moonglow/pcan_pro_x

Device will acts as original PCAN adapter ( PCAN/ PCAN FD/ PCAN PRO /PCAN PRO FD ) and give you full access to CAN bus through original PCAN API libs or other popular tools like BusMaster/PCAN-View. Will also works in Linux through socketcan subsystem or pcanview for Linux.

Notes:
ST bxCAN actually does not support FDCAN frames ( only classic CAN ), but i recommends you to use PRO FD firmware for 2 channel version to achive more performance in windows OS due some internal limitation of windows driver for PCAN PRO version.

Slideshow Bob,
I've not forgot about having a look or play with your new version of the PSU you done, Only been really busy at work (which is good thing under the current circumstances) plus ideally I want to get this version fully up and working. I'm still working on the control software and hardware side of things. Only I've now changed the displays to 3.2" TFT'S screens which is working loads faster than the other screens I was using. Plus much better looking.

I've also added 2 PCF8574's for the buttons and LED indicators to show what's selected and active.

I'm now happy to start the PCB design for the controller, Tidying up the code and adding the rest of the calibration routines can be done at the later stage or while I'm waiting the for the PCB'S to come.

 Undecided
Unless I'm missing something it seems to have zero advantages over the ESP32 which now has a huge following and active user base.

It depends what you're looking for and what you want to achieve.  I like and have used the Bluetooth and WiFi of the ESP32 in some projects, but I have other pending projects that have different design criteria.  The MCU of the Pico (the RP2040) might satisfy these more specific requirements.  In particular the PIO of the chip (the Programmable Input/Output block) could prove useful for generating and processing some of the signals I have to look at.  I've requested a price for the MCU and if low enough could save a large amount on high quantity runs.  That alone might give me a good reason to follow it up.

It's always worth keeping an eye open for new parts; and at £3.60 for a board and a little time testing ideas, I think it's worth a try  Undecided
