i'm working on a SPI NAND Flash applet for #GlasgowInterfaceExplorer. i would like to add the ability to read (and write) data dumps... however, unlike with SPI NOR flashes where the data is located in an flat address space, SPI NAND devices are structured as pages (each has data/spare/[ECC])

if you have a #GlasgowInterfaceExplorer, please try out the new `memory-25q` applet and let me know if it works for you!

so!! i am excited!!! to have finally finished the complete reimplementation of the #GlasgowInterfaceExplorer memory-25x applet for managing SPI NOR flashes. it is called memory-25q and it took an enormous amount of effort, because i have decided to Build It Properly

I would like to formally announce that the #GlasgowInterfaceExplorer revD development (the next iteration: with the same FPGA but 32 digital I/Os and 8 single-ended analog channels that can be configured as 4 differential ones) is well underway with a CS campaign planned later this year; stay tuned!

#GlasgowInterfaceExplorer now has a first-class progress bar implementation with a nice API that takes into account terminal writes elsewhere in the Python application as well as nested or concurrent progress trackers resulting from applet composition!

today's project for #GlasgowInterfaceExplorer: reworking the `memory-25x` applet
this is a very old applet, one of the first introduced. it works mostly fine, but it was designed and implemented before I really knew how to make good applet UIs, and long before I added QSPI support, so it's not […]
#GlasgowInterfaceExplorer now has a modernized version of the `program-nrf24lx1` applet! this lets you program nRF24LU1 and nRF24LE1 devices. they're old and not used much anymore, but the programmer is no less useful for that!

#GlasgowInterfaceExplorer now has a modernized version of the nRF24L01(+) applet, including API documentation! these old RF chips are still relevant to an extent, so I think it's nice to have them supported

#GlasgowInterfaceExplorer now has `spi-controller` applet properly documented! i've also implemented modes 0 thru 2 in the "modernized" version of the applet, as it turns out SPI is basically unusable without these across many devices […]
i'll probably write an SPI NAND flash applet at some point for #GlasgowInterfaceExplorer
the new #GlasgowInterfaceExplorer applet interface is _incredibly_ useful for composing a bunch of things together so you can explore a target
for example, this code composes a clock generator, an UART, and some GPIOs for attacking a NEC 78K0 series MCU paste.debian.net/1408200/

have you ever wanted a #GlasgowInterfaceExplorer, but more wireless? #ESP32JTAG is a Glasgow-inspired device which is specialized for FPGA/MCU programming and debug, and works over WiFi. I think it's very cool and I've backed the project https://www.crowdsupply.com/ez32/esp32jtag

added a new #GlasgowInterfaceExplorer applet, `control-clock`: a simple clock generator for when you just need to feed something into the XI pin of an MCU or something.
you can use it in combination with other applets!
e.g.: `glasgow multi probe-rs ... ++ control-clock --clk A7 -f 2000`

usable in a multi-applet system! `glasgow multi probe-rs ... ++ control-clock --clk A7 -f 2000` works

anyway, i think it should be possible to plug #GlasgowInterfaceExplorer into a completely new computer and start, for example, dumping flash into a file within 30 seconds and with zero Python virtualenv interaction. i have as of this point basically achieved that (tho you need Chrome)
added a WebUSB platform device capability descriptor to #GlasgowInterfaceExplorer so now it pops up a prompt like this if you plug it in and Chrome is running

i figured it's time to put the WebUSB port of #GlasgowInterfaceExplorer software on the website
the web port of #GlasgowInterfaceExplorer can now operate on your local filesystem! (Chrome only)
benchmark results
good news: the webusb version of #GlasgowInterfaceExplorer software is now more or less as fast as native (the latency is a bit worse)
bad news: i have no idea why. i didn't do anything
do i know any people who:
(a) have modern web development experience
(b) like #GlasgowInterfaceExplorer or just want to do something fairly simple and useful
(c) want to work with me on a new piece of the project?

so, i ported #GlasgowInterfaceExplorer to webusb
#GlasgowInterfaceExplorer now has API documentation for most V2 applets published online! glasgow-embedded.org/latest/apple...
