Here’s a PIC programer SMD board for the GTP USB lite pic programmer by cmardone: I created a pic programer smd board for the gtp usb lite pic programmer. Was made using EagleCADSOFT 5.0 2 layer board 0603 footprint for most smd components !! uses a 18F2550 SMD chip from microchip has a mini-A USB connector schematic […]

Open Programmer v0.8.x
Alberto Maccioni posted an update on his multi-chip opensource programmer based on a PIC18F2550. It supports PIC, I2C-SPI-MicroWire EEPROMs, some ATMEL AVRs, and (soon) other devices: In the last few years, as serial and parallel interfaces have almost disappeared, electronics enthusiasts find even more difficult to program microcontrollers; old time programmers don’t work any more; […]
Open Programmer v0.7.x
Alberto Maccioni designed this multi-chip opensource programmer based on a PIC18F2550. Currently it supports PIC, I2C-SPI-MicroWire EEPROMs, some ATMEL AVRs, and (soon) other devices. It even supports some PIC 24Fs, like the 24Fj64GA002 used on the Bus Pirate. In the last few years, as serial and parallel interfaces have almost disappeared, electronics enthusiasts find even […]
USB IR Toy: Calculate transmitter carrier frequency
See the latest version in the documentation wiki. The USB IR Toy raw IO mode samples and replays infrared waveforms. IRIO mode starts with a default 36kHz infrared transmit modulation frequency. The rate can be changed with the setup modulation command (0×02), followed by a byte that sets the pulse-width modulator match value (PR2), and […]
