CNX Software ☛ A closer look at Raspberry Pi RP2350’s HSTX high-speed serial transmit interface
The Raspberry Pi RP2350 microcontroller adds an HSTX (High-Speed Serial Transmit) interface adding the PIOs (Programmable IOs) introduced on the Raspberry Pi RP2040 three years ago. The RP2350 MCU now has three PIOs and one HSTX interface going over 8x GPIOs. So let’s try to better understand what HSTX is exactly, what it is used for, and how it differs from PIOs. We’ll also check out some programming examples in C and MicroPython.

Bunnie Huang ☛ Winner, Name that Ware July 2024
The ware for July 2024 is an Ingenico Axium DX8000. I hadn’t had a chance to tear down a modern POS terminal myself, so it was pretty interesting to see all the anti-tamper traces built into the product (thank you jackw01 for sharing it!). [...]
