Re: Ideas for next evolution of pyboard
What I've dreamed about for a long time is more RAM. Put 1Mb external SRAM on the current board, and I would be VERY satisfied.

Re: GPIO as CS for SPI
I've used GPIO for SPI-CS with good results, nothing unforseen happened.

Re: My own retro computer system
When I use the bread-board I do have problems with long leads and 20MHz SPI. 10MHz with long leads or shorter leads, no problem. Proto-boards have been error free as well. I2C have not been problematic at all. Lucky I guess. Different chips seem to have different weaknesses though according to: http...

Re: My own retro computer system
Yes, my bus is actually like UEXT without the UART-lines. I won't use those modules though, as I want to have fun doing my own HW and SW

My own retro computer system
I've started a project that tries to recapture my love for the old home computer concept, where there is a main unit that is expandable via cards. Like a cross between an Apple 2 and PC/XT. I've designed and built an expansion bus with I2C, SPI, power and slot-select on each slot. 8 pins for each sl...

Re: Port vs Pin
Many thanks Dave, precisely what I nedded!
I have read parts of the ref manual, and just wanted to know if there were any specific stm-commands available, rather than writing assembler.

Port vs Pin
I have searched but found nothing on how to access ports as a byte rather than as pins only.
What I'd like to do is connect an LCD, which has an 8-bit data port and 4 bits worth of control pins.
I was hoping I could access it something like this:
data_port = Port (PA0-PA7, output)
data_port.set(255)

Simple serial
I just soldered the connectors on my board and sent "Hello world!" to a serial VFD. The soldering took much longer than the coding. Great! I really like the simplicity of MicroPython.

Re: REPL docs?
Thanks for the reply, REPL-coding became much easier!
Hopefully this info will also end up in the documentation soon? Or is there any other reference documentation regarding REPL?
