Expected to create a 10us pulse in python using time.sleep() on my raspberry pi:
GPIO.output(pin_trig, GPIO.HIGH)
time.sleep(10E-6)
GPIO.output(pin_trig, GPIO.LOW)
Only to see a 95.5us pulse with my #siglent scope
ESP32-P4 + ESP32-C5 board features Raspberry Pi-compatible MIPI connectors for official displays and camera modules
We've come across an ESP32-P4 + ESP32-C5 board that looks similar to the Wireless Tag WTDKP4C5-S1 board, but is even more compact and features four MIPI connectors, including two whose pinout is compatible with Raspberry Pi camera modules and displays. Maker Go calls it the "ESP32P4C5 core board" and features an "ESP32-P4-Module" with ESP32-P4 MCU with 32MB PSRAM, an ESP32-C5 dual-band WiFi 6 SoC, nd a 16MB NOR flash. Besides the MIPI connectors, the board features three USB ports, one for debugging, and two Type-C/A ports sharing a USB 2.0 data connection, a built-in MEMS microphone, a speaker connector, and two 34-pin headers for expansion. ESP32P4C5 Core Board specifications: Main SoC β Espressif Systems ESP32-P4 CPU Dual-core 32-bit RISC-V HP (High-performance) CPU @ up to 400 MHz with AI instructions extension and single-precision FPU Single-RISC-V LP (Low-power) MCU core @ up to 40 MHz with 8KB of zero-wait TCM RAM

This week's exciting forays into computing:
π I am loving Debian + KDE on my main computer. I miss nothing from Windows. (What the hell takes Windows Explorer so long? Dolphin is instant!)
π Steam/Proton run some of my games better than Windows did.
π While Windows removes the ability to customise things with every update, I can customise every little thing on Linux.
π Wrote my first C program that does GPIO stuff on Raspberry Pi.
