Okay well this is a long shot… I’m trying to read (and eventually write) from/to an Infineon F-XC866 4FR 8-bit MCU… and every link from Infineon to Dave bench, Dave, Dave IDE, FLOAT, etc led to a dead end.

Does anyone have this software laying around, or maybe can point me in an alternative direction to reading and writing these things?

My only real experience with MCUs is ESP32’s, and arduino IDE just makes it too easy. Even espressif’s tool chain didn’t seem this bad.

1000 richest people are approched. "The end of the world is here. Time to go to your doomsday bunker", they are told. The billionaires nodded. They knew this was coming. They were prepared.

So they gathered their loved ones and locked themselves in luxury bunkers. No contact to outside world.

10 years later they emerge. The world has healed. The air is breathable, people are happy. "What was the catastrophy?" they ask the first person they meet.

She screams: "THEY GOT OUT!!!"

@hacks4pancakes hey Lesley! All I can say is I hope to have a job like yours one day! Currently a repair technician/engineer for biomedical equipment.

@mttaggart ah I see they sent that to everyone. I assumed that was the case

@hacks4pancakes yep, pet peeve, but also increases risk for no reason. They’re in the wrong - they should fix themselves, but I’ll fix it myself since I know many don’t care.

If you can slow down or speed up so no car is around you, it increases your “escape routes”… say they have a mechanical failure that causes them to swerve, or you do.

I mean, I understand the risk is actually low, but the minimal effort to mitigate it makes it a no brainer to me.

I even do this in heavy traffic - always try to have an open spot to one immediate side at the minimum, plus safe following distance.

@gsuberland and idk if this is your thing, but if it is, here’s a bonus for your troubles:

@gsuberland Ooooh I'll have to keep this in mind - never really used them. I'm US based, so the digikey shipping matches the cheapest options on LCSC. Though the parts have significantly cheaper alternatives!

Problem is, the connectors on the antennas are borked too. So $12 for a pair of those, plus another $15 for the smd connectors.

Already bought a BGA stencil set, solder balls, and NVME drive to transfer into the laptop for $50 USD. The Spousal Approval Factor begins dropping significantly as I go over $50 lol. Especially since I have no idea if I'm going to be successful on my first BGA soldering attempt!

@gsuberland I just can't get over that shipping from DigiKey is more than all the parts combined 😂

@gsuberland 802.11ac, so 5 GHz, but compatible with 802.11a/b/g/n... It's on a Microsoft Surface 1769 laptop.

My biggest question is which pad the center conductor vs. outside conductors went to >.>

2024-08-18

@gsuberland Heeeey Graham, have a question for you that I think maybe you're qualified to answer (I love seeing all your EE stuff)...

I broke off a pair of MHF 4 receptacles for wifi antennas. In the datasheet, it mentioned 50 ohm impedance.

Can I just... solder the coax shield & wire to the pads that this connector came from? Do I need to add in a resistor as well?

I understand this isn't *correct*, but I'm wondering if I can get away with it on the cheap(er than buying replacements).

Hey folks,

My wife asked a favor of me since I happen to have quite a few acquaintances through broadly gestures

She's a first grade teacher, in a title 1 school district. I don't know if you have a spouse or loved one who works in public, primary school, but if you do, you're aware that the school district doesn't supply nearly enough to keep a school room running.

Much of the time that which the district supplies, and that which you need to handle the needs of a class of (this year, 29 first graders) is a significant gap.

We're no stranger to opening our own wallets to buy supplies, snacks for the kids, ink for printing, and so on and so forth.

So... that brings me to this, my wife's Amazon wish list.

amazon.com/hz/wishlist/ls/15VJ

If you're feeling generous and want to help her out, we would both appreciate it, and I'm 100% sure the students of her classroom will appreciate it as well.

If you can't spare anything, or have teachers in your life you already have to worry about raiding the dollar store, the aldi's aisle of shit, or the dollar bins at target, or you just can't, don't worry about it, thank you for taking the time to read this.

Edit: If you could boost this for reach, I would appreciate it. Again, dont feel obliged to do anything, thank you in advance if you choose to do literally anything, even helping the teachers or school districts near you instead !
