Quickstart board and raspberry pi

dr hydra

Can you plug the quickstart board directly into the raspberry pi usb port...does the RPI output enough power? can you communicate with uart between the boards? Does the RPI recognize the FTDI chip? What happens as the RPI boots..does the uart cause any communication issues? I know that is a lot of question...any help is much appreciated:)

dr hydra,

You should be able to talk to a QS over USB. Power requirements depend on how heavily the Prop pins are loaded. But just getting up and running should be fine. The new Pi 2 can supply a lot more power and generally has less power related issues.

You can connect a Prop directly to the Raspi UART on it's GPIO header. prop-gcc, SimpleIDE and PropellerIDE are usable on the Pi and should be able to program a Prop over that UART. If not I have a prop-loader that can.

FTDI based USB/serial adapters are no problem for the Pi.

BY default the Pi sends boot messages over the GPIO header UART. That can be disabled in raspi-config.

I think you should get along OK with a QS and Pi. If any problems turn up just ask here and I'm sure we can fix it.

If you run into any issues, edit /boot/config.txt and add a line "max_usb_current=1"

Any USB based prop board (that does not draw more than ~500mA from USB) should work fine with a Pi.

As Heater says, Propeller boards without a USB interface (ie older proto boards, boards from people on the forum) can work directly with a Pi, just wire Rx, Tx, and use GPIO#17 for /RST (pull it high) from the 26/40 pin header

Both have 5 pin comm headers, the first four pins are magically identical to a PropPlug so all that is needed is a 4 pin cable to program Propellers.

I have a quickstart plugged into a Rpi2 in my living room. works great.

Great info...thank you...
