// RFM22B hardware layer
//
// This module uses the RFM22B's internal packet handling hardware to
// encapsulate our own packet data.
//
// The RFM22B internal hardware packet handler configuration is as follows ..
//
// 4-byte (32-bit) preamble .. alternating 0's & 1's
// 4-byte (32-bit) sync
// 1-byte packet length (number of data bytes to follow)
// 0 to 255 user data bytes
//
// Our own packet data will also contain it's own header and 32-bit CRC
// as a single 16-bit CRC is not sufficient for wireless comms.

Added framework for rfm22b com device.
2012-02-29 05:30:06 +01:00
Split out the PipX radio interface from RadioComBridge module to a separate Radio module. Now the RadioComBridge module just routes messages between the com ports and handles sending/receiving the PipX UAVOs.
2012-08-25 04:25:02 +02:00
#include <pios_spi_priv.h>
Added start at a modified PipX packet handler.
2012-03-16 03:29:54 +01:00

2013-03-31 17:37:14 +02:00
#if defined(PIOS_INCLUDE_GCSRCVR)
Added optional output of GCSReceiver from the OPLink to the FC. This will happen automatically if a PPM packet is receive, and PPM output is disabled.

2012-09-17 04:33:30 +02:00
#define EVENT_QUEUE_SIZE 5
RFM22B: Changed default (initial) air baud rate to 9600. Also some code cleanup.

#define RFM22B_DEFAULT_TX_POWER RFM22_tx_pwr_txpow_0
USB/COM/RFM22B: Added a standard com callback to test for link availability. This replaces the PIOS_USB_CheckAvailable function with a generic PIOS_COM_Available function. This is now used by the RFM22B com driver to test if a good link is up. This was originally written by James, and Brian merged it into the latest RFM22B branch.

// The maximum amount of time without activity before initiating a reset.
RFM22B: Start at cleaning up the processing interrupt handling, and starting to make it more of a state machine. Also removed the supervisor, which was causing unnecessary resets. The supervisor functionality is not in the the driver thread.
2012-09-15 04:30:02 +02:00
#define PIOS_RFM22B_SUPERVISOR_TIMEOUT 100 // ms

RFM22B/RM: Added rfm22b com device, moved remaining functionality in the radio module to the rfm22 driver, and simplified configuration of the PipX/OPLink. The radio device now presents itself completely as a com device, both in RadioComBridge (OPLink devices) and Telemetry (RM). Also change the PipXStatus and PipXSettings UAVOs to OPLinkStatus/OPLinkSettings.

static uint8_t rfm22_read(struct pios_rfm22b_dev *rfm22b_dev, uint8_t addr)
OP-914: Additional cleanup of the RFM22B driver code. Updated to code to the current coding standard. Added Doxygen documentation. Rearranged functions into functional groups to simplify reading the code.

{
uint8_t out[2] = {addr & 0x7F, 0xFF};
uint8_t in[2];
rfm22_assertCs(rfm22b_dev);
PIOS_SPI_TransferBlock(rfm22b_dev->spi_id, out, in, sizeof(out), NULL);
rfm22_deassertCs(rfm22b_dev);
return in[1];
}
Moved RFM22B code from PipXtreme to pios_rfm22b.c driver. The radio is now passing data.
