crystal-11 AVR Wizard
AVR peripheral init code generator for the ATmega32A , inside VS Code / Cursor.
Configure GPIO, USART, ADC, timers, SPI, I2C, and external interrupts in a wizard, then generate main.c and optionally create a ready-to-build project. Named after 11.0592 MHz — the crystal that gives 0% baud-rate error on standard serial.
Features
Peripheral wizard: GPIO, USART, ADC, Timer0/1/2, SPI, I2C (TWI), INT0/INT1/INT2
Generates C init code for ATmega32A (F_CPU=11059200UL)
Create a new project folder with main.c and C/C++ IntelliSense settings
Flash a .hex via avrdude (USBasp, AVRISP mkII, Arduino as ISP, STK500)
Auto-detects avr-gcc (Homebrew, apt, WinAVR) or use a custom path
Getting started
Install the extension.
Open the crystal-11 AVR Wizard view in the Activity Bar, or run crystal-11: Open AVR Code Wizard from the Command Palette.
Enable the peripherals you need, generate code, then Create Project or save to a file.
To flash: right-click a .hex file and choose crystal-11: Flash to Device , or run the command from the palette.
