Unable to upload RF24Mesh_Example.ino to ATTiny85 #32

arjun-g · 2015-08-02T13:47:24Z

Will RF24Mesh work in ATTiny85 ? I tried uploading the sketch but I am unable to do it. I removed all the Serial write. When I start building it just gets stuck at some point. Are any more steps needed for this ?

Do you know where it ends? if you use arduino ide turn on Debugging option in Preferences

I tried with RF24Network_Dev and this is what I get.

My master node would be a Arduino Uno I don't face any issue in uploading the master sketch in it. With ATTiny85 I am getting this.

This is the modifed code I use

/** RF24Mesh_Example.ino by TMRh20
 *
 * This example sketch shows how to manually configure a node via RF24Mesh, and send data to the
 * master node.
 * The nodes will refresh their network address as soon as a single write fails. This allows the
 * nodes to change position in relation to each other and the master node.
 */

#include <SPI.h>

/**

 * to change dynamically with physical changes to the mesh.
 *
 * In this example, configuration takes place below, prior to uploading the sketch to the device
 * A unique value from 1-255 must be configured for each node.
 * This will be stored in EEPROM on AVR devices, so remains persistent between further uploads, loss of power, etc.

Tried the above change and the first error is resolved. But the SPI issue is still there. Any idea on why its happening ?

TMRh20 · 2015-08-02T16:11:29Z

Yup, just don't #include <SPI.h> with ATtiny, the functions are built-in.

arjun-g · 2015-08-02T16:12:54Z

Just found that. Thank you :)

arjun-g · 2015-08-02T16:27:49Z

I am using the 3 pin configuration in ATTiny85. Arduino Uno will be the master. Will mesh work in this scenario ?

TMRh20 · 2015-08-08T03:39:48Z

If you haven't tried it yet, it should work.

Avamander · 2015-09-08T19:56:42Z

@TMRh20 Close this issue please.

venus696 · 2018-06-30T09:39:47Z

I am running an example "Mesh Example Master To Nodes" from trmh20's Mesh library.
I am getting the error mentioned below.
can any body help me to solve this.
