#Pic function generator 32 bit#

The major pitfalls for those new to the 24 and 32 bit cores are: I don’t think it’s very useful for the 1kB challenge though, the number of instructions decreases significantly with 24 and 32 bit cores. If you’re unfamiliar with the 24 and 32 bit cores, it will take a lot more time to properly set the chip up for your projects, but it’s well worth it IMHO. With the PIC32MZ family clocks of 252 MHz are possible and It was rock stable :)Īs a general rule instruction cycle is osc divided by:ġ for PIC32, though because it can cache and branch predict (IIRC) it can be about 2/3.

I’ve managed to overclock a PIC16F1937 to 80MHz using a 20MHz osc with the PIC 4x PLL enabled, which results in 20MIPS. If it’s speed you need in the 8 bit PIC, I’d recommend an USB capable PIC, which runs on 48MHz, so it runs on 12MIPS.

In fact, there are hardly any components at all beyond the Raspberry Pi, the PIC32, and a MCP4822 digital-to-analog converter. The project documentation notes that improvements can be made, the speeds are a far cry from regular bench equipment, and the software lacks some typical features such as triggering, but overall not bad at all for under $50 of parts.

The readings are sent in batches from the PIC32 to the Pi, where the plot is updated every 30 ms so that user does not perceive any visible lag. The idea of combining them into PicBerry is to get the best of both worlds, with the Pi and PIC32 each doing what they are best at. The Pi takes care of the user interface and other goodies, and a PIC32 over SPI is used for 1 MHz sampling and running a DAC at 500 kHz. That’s where the hybrid approach comes in. It’s based on the Raspberry Pi, features an intuitive Python GUI, and can generate and measure simultaneously.īut wait! The Raspberry Pi is a capable little Linux machine, but meeting real-time deadlines isn’t its strong suit.

The PicBerry is a student final project by, , and that takes a hybrid approach to creating a portable (and affordable) combination digital oscilloscope and function generator.
