# 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 |
