Re: Teensy 4.0 & 4.1
From which flash device are you booting? The 1050_EVK is currently configured to boot from HyperFlash. You can configure the flash type with BOARD_FLASH_TYPE in boards/<BOARD>/mpconfigboard.mk. It is important that the configured type matches the desired flash on the board and the boot selection si...

Re: Teensy 4.0 & 4.1
@Roberthh I'm building the firmware from your repository for the following boards and I have some issues. Seeed's Arch-Mix based on RT1052 VisionSOM-RT module with RT1062 on VisionCB-RT-STD carrier board Both boards are mostly compattible with MIMXRT1050_EVK and MIMXRT1060_EVK, same basic setup (USB...

Re: [STM32F405RG] or [STM32F7XX] based Board with Ethernet and RS485
Interesting that these are based on ESP32. I would question whether this is sufficiently resilient for industrial applications. In my experience (backed up by @kevinkk525) it suffers from occasional spontaneous reboots, even taking extreme precautions with the power source. By contrast STM-based Py...

Re: New STM32H743VIT6 dev boards
I have found this board delivered for $26AUD https://www.aliexpress.com/item/4001048553596.html?spm=a2g0s.9042311.0.0.3da24c4d5Oqsga at that price I just have to get 1. Considering the amount of flash and RAM on this board and the fact it has both a header for a small SPI TFT and a FPC connector fo...

Re: FTDI EVE touch display driver?
There is a fully working eve module in my ESP32 MicroPython port, unfortunately I've never had a time to fully document it, but it supports all eve features and works very well (I'm using it for years...). It depends on some other modules, but it could be a start point if you want to port it to your...

Re: TI ADS1219 ADC driver
A noob question here. If it is a 24bit ADC and your Vref is 3.3v then the sensitivity it has to read is 3.3v/(2**24) = 0.00000019669532775878905 volts What sort of hardware would be needed to decouple and isolate the ADC so that such fine voltages are not just inducted from the air?? I have used th...

Re: Free RAM on MicroPython boards
As for the 8MB RAM it's not clear to me how this is going to be utilised for MicroPython. Upper 4MB cannot be used for MicroPython heap. It can be used for storing data or for RAM file system , I'm working on a driver for it. It will enable very fast writing speeds (practicaly the same as read spee...
