The final instalment of my experiments with using an #STM32 #microcontroller in place of an EEPROM in a #homebrew computer. (Medium sub required.)

McROM redux: improving the STM32 microcontroller-based ROM emulator

The first version worked in my homebrew computer, although not without persuasion. Let’s see if we can do better.

IPic – A Match Head Sized Web-Server

iPic는 세계에서 가장 작은 TCP/IP 스택과 HTTP 웹서버를 단일 마이크로칩에 구현한 초소형 웹서버입니다. PIC 12C509A 마이크로컨트롤러 기반으로 256바이트 크기의 TCP/IP 코드와 HTTP 1.0 서버를 포함하며, 24LC256 EEPROM에 웹페이지 파일을 저장합니다. 이 기술은 가정용 전자기기, 산업용 장비, 사무기기 등 다양한 기기를 인터넷에 연결해 웹브라우저로 원격 제어할 수 있게 하여 IoT 초기 개념을 구현합니다. 특히 저전력, 초소형, 저비용으로 네트워크 연결이 어려웠던 소형 장치에 TCP/IP 접속을 가능하게 하는 점이 주목됩니다.

I found a custom-made pocket computer based on Raspberry Pi 5 with USB support. I'm leaving this here for those interested in DIY projects.

Mandatory hardware checkpoint: Bad Apple on the 0.96" OLED. 📺

But plot twist: this isn't pre-loaded on the flash memory. I'm actively streaming the frames live over Wi-Fi from a web browser on my laptop to an ESP8266. It handles live camera feeds and a drawing canvas too!

And now BOTH programmers work CONSISTENTLY. Regardless if I use the IC-Clip or the socket.

ARE YOU FUCKING SHITTING ME. WHAT THE FUCK?!?!

So, wtf is wrong with my setup?

Can someone recommend a "Chip programming for idiots" course? I now have another programmer (a EZP2023+) and another clip. And I also bought blank W25Q32BV chips to test.

It detects the chip. It (pretends to) write to the chip. It (pretends to) read from the chip.

But the data is always the entire chip being filled with 0xFF for whatever reason...

wtf is going on with this chip?

Need to use your laptop #keyboard on your phone? This #CircuitPython project forwards laptop keystrokes via a #microcontroller over BLE HID, turning your computer into a wireless keyboard. Check it out: https://github.com/urfdvw/keyboard-forward
