Chip suggestions, fast 5V compatible
Posted: Sat Dec 09, 2023 10:27 pm
I am looking for suggestions for a fast, 5V compatible chip/dev board.
I am currently using an Arduino Nano V3 where I am sampling 4 analog channels and using an interrupt to output a simple servo calculation to an SPI DAC (MAX5216). I have to run the interrupt at 1khz because the chip is not quite fast enough to run it at 2khz and there is no way to get a time interval between 1khz and 2 khz. It runs adequately at 1khz, but I really want to run the servo update at 2khz, so I am looking for a faster mcu. I have some analog circuits that are all based on 5V signals and I don't want to change those to scale the signals down to 3.3V.
If anyone can suggest targets that are 5V compatible with a faster clock (>32mHz) and compatible with Flowcode, I would appreciate the advice. I did find the PIC32CM series (5V and up to 48mHz), but it is not listed in the "supported devices" page. Maybe it is similar enough to other PIC devices, but I have no experience with PIC devices on Flowcode.
