# nrf24le1-libbcm2835

A simple command-line interface with Nordic nRF24LE1 using 

RaspberryPi over bcm2835 library.

This tool started as a userpace port of **@hltrd** nrf24le1

linux device driver.

## Features

- Program memory read/write

- NVM memory read/write

- InfoPage handling

## Requirements

- You must be using a Linux distro with `bcm2835` and `rt` 

libraries installed.

- If your partition is mounted with `nosuid` probably you 

will need to run this tool as root.

## Command Line Format

For further development, the tool should conform to the above protocol.

### Miscellaneous

`nrf24le1 show`

Show the FSR register and make sure we can modify it, this demonstrates proper

communication on the SPI bus to the nRF24LE1 module.

`nrf24le1 reset`

Reset the unit on the programmer, this resets the MCU to start the program afresh.

### Reading data from nRF24LE1

`nrf24le1 read infopage [filename]`

`nrf24le1 read firmware [filename]`

`nrf24le1 read nvm [filename]`

All read operations dump data to stdout by default, in Intel Hex format. 

It's possible to provide an optional filename as an argument.

When a filename is specified and the extension matches .hex or .ihx the 

dump will be saved in Intel Hex format, otherwise the binary format will 

be used.

### Writing data to nRF24LE1

`nrf24le1 write firmware [filename]`

`nrf24le1 write infopage [filename]`

`nrf24le1 write nvm [filename]`

All write operations expect data from stdin by default, in Intel Hex format.

It's possible to provide an optional filename as an argument.

When a filename is specified and the extension matches .hex or .ihx the 

dump will be saved in Intel Hex format, otherwise the binary format will 

be used.

### Additional Parameters:

(not yet implemented)

| Parameter          | Function                      |

| ------------------ | ----------------------------- |

| `--offset N_BYTES` | Skips N_BYTES bytes           |

| `--count N_BYTES`  | Read/Write only N_BYTES bytes |
