I've got one of these boards kicking around:
ARM Cortex-M3 CPU, wifi, my board has the NFC, there is one that looks like a NodeMCU, it has basic features. I've not used the smaller board.
I'm using an Arduino bootloader on my Ameba for now, its able to have the flash ROM mounted, and the Arduino toolchain copies the compiled firmware file over, a bit like the Freescale Kinetis "Freedom" boards I was using in 2013. There is a JTAG port, non-populated, I don't have the JTAG programmer - of course.
This board with an Inferno system on it, and perhaps an SPI LCD driver, would be awesome. I see now the Nextion HMI LCDs are a serial port controlled affair, you upload your graphics and all that to the micro SD card as another compiled firmware. I was going to source a Nextion HMI along with a Cytron motor driver late next week from Western Australia, no holding my breath on when it'll turn up however.
The board and screen assembly is meant to go into a control head project for a potentially remotely controlled ride in locomotive, a grid operating system would be perfect for what I'm trying to accomplish. It will have CAN Bus, RS485, Dallas One Wire, et al, all embedded type communications standards, and be a rather souped up PLC type affair.
Except I have little idea of how to port anything. I guess I could go back to the work done on Lynxline, and try to replicate it somehow, I believe I read Charles report done for him on Vita Nuova about the Styx on a Brick, I'd gotten rid of my Lego RIS2.0 many years before I saw that report, shame. The "Brick" was quite limited, so is 9Pea on ATMega, iirc...
My $0.02 likely not worth $0.02 due to inflation. Happy New Year all!
