The high-performance Microchip picoPower 8-bit AVR RISC-based microcontroller combines 4KB ISP flash memory, 256-Byte EEPROM, 256B SRAM, 12 general purpose I/O lines, 32 general purpose working registers, an 8-bit timer/counter with two PWM channels, a 16-bit timer/counter with two PWM channels, internal and external interrupts, an 8-channel 10-bit A/D converter, programmable gain stage (1x, 20x) for 12 differential ADC channel pairs, programmable watchdog timer with internal oscillator, internal calibrated oscillator, and four software selectable power saving modes. The device operates between 1.8-5.5 volts. By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed.

“It was December 2020, deep into the second Covid-Lockdown and I thought about how to give away some smiles for christmas to my family and friends. Besides, I wanted to have some fun with pcb-layout and microcontrollers. The result: This …

Tiny AVR Programmer

“Here you get your own very small AVR programmer board that you can put in your keychain. Today I will build an AVR programmer based on the FabOptimus that built by Ali Shtarbanov. It’s very well documented and makeable …

Making a wireless joystick

“I always liked the design of the Wii’s Nunchuck controller. But normally you can only use them if they’re physically wired to another device called the Wii Remote. However, with some hardware and software tinkering and time, it …
