on 02024-05-09#video of #microcontroller #hardware, the #Puya PY32 Cortex-M0, with #pricing of 10¢ in quantity 500. Over ten minutes of worthless talking-head footage at the beginning of the video. 5.5 volts, reprogrammable. Part numbers sound like STM32F0 clones? PY32F0032A is 24MHz, 20KiB Flash, 3KiB SRAM, 18 GPIOs, 1 ADC, 3 timers, SPI, UART, I²C; the 30¢ PY32F030 has, among other things, 32KiB Flash, 8KiB RAM, and 48MHz; the 50¢ PY32F072 even has CAN and USB. You have to get them off LCSC. He’s using Keil and programming it with an ST-Link v2, and some people use Stm32Cube. Screenshots of py32.org, which still has Puran’s documentation for their chips. He’s only able to get the code to flash at 3.3V. He recommends reading the STM32 manual to learn how to set up the ADC, so I guess this really is an #STM32 clone. (He points at ST copyright notices in the BSD-licensed HAL source code.) He also recommends reading Puya’s example code in the zip file and the well-written PY32F030 series reference manual in English.
