Re: hcsr-04 how to fixed string

I do have the 16x2 display that was described in adafruit's article :)

but I also have the DVK511 board from waveshare and the 2,2" TFT LCD display with touchscreen dedicated to that board
I'm just a noob at programming :(

Re: hcsr-04 how to fixed string

I also have a TFT LCD 2,2" with touchscreen from waveshare connected to my DVK511 board but I can't make it work (the driver loads properly but no display)

still I don't know how to connect HC-SR04 and not crash RTC DS1307
do you use any RTC?

Re: hcsr-04 how to fixed string

that's right, I didn't use a display yet with hc-sr04
I will try your method and the display I have which is 16x2 HD44780 standard display

Re: hcsr-04 how to fixed string

can you tell me how did You connect it to pi, how many resistors did You use and the whole script that You used?

I tried to use HC-SR04 but it was killing my RTC DS1307

Re: USB DAC

I have Texas Instruments PCM2707 working on my raspbian
You just need to edit file /etc/modprobe.d/alsa-base.conf
and change

Code: Select all

# Keep snd-usb-audio from beeing loaded as first soundcard
options snd-usb-audio index=-2
-2 to 0 :)
