I feel like the flipper zero has actually, finally become useful for me now that I can use it to dump/flash SPI flash. With it, and a Pomona clip you can dump / flash with nothing else, not even a computer needed.

Now, to get around to the two #logicanalyzer pods and all the grabbers. I had code that would run fine from the #89C52 memory, but wouldn't run from the #eeprom. I had verified that the static ram worked, but the EEPROM seemed to be acting odd. My nice #Siglent scope only has 16 logic channels. Not enough to watch the latched address bus and the data bus. Yes, I could have done it, but why not break out the #HP1532B? Plenty of channels there.

@matt_trentini @dave @fuzzySynths I definitely walked in with a plan to bitbang. Reading about #micropython interrupts disabused me.

I'm not sure what RMT is. I looked at an #I2S device but it kind of sucked. The #ad9833 is #SPI and works beautifully but has predetermined waveforms.

I wondered about storing wfs in an #eeprom but it needs more thought. Still need to output a phase ramp at a high rate. #esp32->DDS ramp->eeprom->DAC?

En préparation pour #TIV23 Tech Inn'Vitré du 10 au 12 février. Sur le stand @framboise314 un parcours à effectuer avec le rover #CrowBot #Bolt d' Elecrow Chrono avec @arduino
au 1/1000, mémorisation du meilleur temps en #EEPROM

Step two, figure out which one of these removable devices is the #EEPROM programmer from the Chinese company so that I can assign it to a VM.

This is easy!

@polpo do you know any good preferably written references on simple low frequency 4k #eeprom circuits. I want to do something but need to read a lot first so I seem at least as smart as a highscooler.

OK, so decided before I move over to building the #eeprom programmer for my Ben Eater 8 bit CPU, the fact #Authentik isn't auth'ing correctly for Gogs and my Synlogy via #LDAP is driving me nuts, so I think that's today's tasks...
