DDRB &= ~(1 Echo pin of Ultrasound sensor - input USI_DDR &= ~(1 Trigger pin of Ultrasound sensor - Output Ui8Mode = TRANSMIT // Switch to transmit mode When switching between tri-state (ĮCHO_DDR &= ~(1 i16Level = i16Level // Read level Switching Between Input and Output (From the data sheet) I am not sure I am getting it right and ECHO signal goes haywire generating ECHO-ERROR. It suggests that there needs to be an intermediate step to be added when switching between input and output. Ģ) When the NRF is also included for transmitting the distance following is the trace.įrom the data sheet, I see that there is a process described when one has to switch a pin between input and output. The traces are as expected - the width of the echo pulse is proportional to the distance.

I checked the trace of the echo and it is as shown below.ġ) When the NRF part of the code is not running. This sequence returns the ECHO ERROR instead of data.

Initialize NRF transreceiver (PB4 is CSN pin and is to be configured as output) initialize the ultrasound sensor (PB4 is made as input) The PB4 pin is an INPUT (ECHO) pin for the ultrasound sensor and OUTPUT (CSN) pin for the NRF The issue is when I have both the NRF *and* Ultrasound sensor connected to the board and they are sharing PB4 pin. The NRF part also works as expected - it transmits a series of bytes to the central panel(The ultrasound sensor is disabled) I have tested the Ultrasound sensor working allright on the ATTINY85 board - it measures the fluid level and returns the level in cms (the NRF is disabled). The transmitter is based on an ATTINY85 at 16MHz (Digispark board) and I have to share one PIN (PB4) between the NRF and the ultrasonic (HC-SR04). Running a simple blink program on a breadboard with a stand-alone ATtiny85.I am trying to build a fluid level measurement system that reads the fluid level in a tank and transmits it to a central panel via the NRF24L01. Now, you can use the newly programmed ATtiny chip in a project, without have to log around the entire Arduino with it. Now, all that needs to be done is plug the USBasp in to the USB port of a computer and hit play, here is what the console will look like when it is all working:

I can quickly program ATtiny chips by putting the chip in the IC socket and plugging an USBasp in the ribbon socket. If you do this, I recommend running some tests on a breadboard first and making sure you have all your pins properly connected before soldering it together. Setting these pins up can be done in a couple of ways, I decided to make a dedicated board for this with a socket, so I can program chips quickly in the future.

We are now all set from the software end, we need to then wire up the hardware. The following pins will need to be connected: Next we need to set the board to be the ATtiny and the programmer to “USBasp”, use the following screenshot for reference:
#Attiny85 port pins address install
Install the attiny boards that appear (you should only have 1 result).Click “OK” to close the URL editor, and “OK” again to close preferences.Click on the button to edit the “Additional Board Manager URLs”.Next, you need to install the ATtiny board in to the Arduino IDE.
#Attiny85 port pins address drivers
Once the drivers are installed, plug in the programmer and confirm your the drivers are working in device manager:

A lot of sites will say you need to disable driver signing and do a whole bunch of steps, but the drivers found here will install on Windows 10 (they are signed) when installed using the installer (but not when you try to install the drivers yourself). If you are on Windows, you will need to install the drivers for the programmer. The one I used is this one found on Ali Express. Getting your code on to the stand-alone Atmel chip is a little more tricky there are ways to program the chip with an Arduino, but they aren’t as easy as using a USBasp AVR programmer. The Arduino makes putting your code and powering your Atmel chip very easy. All you need to do is buy an ATtiny45, ATtiny85 or similar Atmel chip, and then upload your program to it. What you really need is just the microcontroller to run your code and control the pins. The problem is that an Arduino is a big and relatively expensive device that has far more things than necessary for your project. So, you’ve created a project on an Arduino and want to deploy it in to the world.
