2016-07-12mrf24j40: avoid uninitialized byte in SPI transfer to radio.Walter Mack
isr function issues SPI read command to mrf to obtain INTSTAT. SPI transfer is 2 bytes, but value of 2nd byte is not defined. This had the effect that only the first ISR worked as intended. The second ISR read incorrect INTSTAT values. Observed on Raspberry PI B+. Signed-off-by: Walter Mack <wmack@componentsw.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2016-07-08fakelb: allow to run as monitorAlexander Aring
For my RIOT-OS in userspace experiments I need to create a fakelb monitor interface. The fakelb doesn't filter anything on L2 and is a purely raw interface. Because nl802154 checks on promiscuous mode which need to supported by creating monitors this patch adds some no-op promiscuous mode setting and the promiscuous flag.

2016-04-20at86rf230: increase sleep to off timingsAlexander Aring
I expierenced when setting channel while sleep mode it didn't changed the channel inside the hardware registers. Then I got another report of an user which has similar issues. I increased the sleep to off state change timing, which is according at86rf233 at maximum 1000 us. After this change I got no similar effects again. I tried another option to wait on AWAKE_END irq, which can be used to wait until the transceiver is awaked. I tested it and the IRQ took 4 seconds after starting state change. I don't believe it takes 4 seconds to go into the TRX_OFF state from SLEEP state. The alternative is to increase the timings which seems to work.

2016-01-03ieee802154: cc2520: Check CRC & add promiscuousBrad Campbell
This patch adds checking the "CRC_OK" bit at the end of packets coming from the CC2520 radio. It also adds support for putting the radio in promiscuous mode (in which packets are not dropped if the CRC fails). In promiscuous mode the AUTOCRC flag is cleared so that the driver can pass the received CRC to the monitors. The radio now defaults to frame filtering (checking that the destination and PANID in the incoming packet matches the local node). This matches the other 15.4 radios and is what a user would expect to be the default. Other changes: 1. Adds LQI calculation 2.

2015-09-22at86rf230: support edge triggered irqAlexander Aring
This patch adds support for edge triggered irq types. We remove the locking for irq resources by enable/disable irq and allocate directly some heap buffer at isr. We have still a enable/disable irq path but this is for level-triggered irq's which need to be disabled until spi_async clear the irq line. There is usually a little race condition between "irq line cleared" and "enable_irq". When in this time a edge triggered irq arrived, we will not recognize this interrupt. This case can't happend at at86rf230. The reason is that we unmask TRX_END irq's only which indicates a transmit or receive completion, which depends on the current state. On Transmit: TRX_END arrived and transceiver is in TX_ARET_ON state again, in this state no other TRX_END can happen until we leave the state. On Receive: This is protected with the RX_SAFE_MODE bit which leaves the transceiver in RX_AACK_BUSY until we readed the framebuffer. In this state no other TRX_END can happen. Tested with RPi where I first detected issues between edge/level irq's. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

2015-09-17at86rf230: change trac status check behaviourAlexander Aring
When transmit is done, indicated by trx_end irq, we do first a force state change to TX_ON and then checking the trac status, if the trac status is unequal zero we do a state change to TRX_OFF. This patch changes to the following behaviour, we first check on trac status after trx_end occurs and then doing a normal change to TX_ON without do the state change to TRX_OFF when trac status is unequal zero. The reasons are that the datasheet doesn't described when the trac status register is cleared, we should doing to evaluate the trac status at first. The reason to remove the TRX_OFF change if the trac status is unequal to zero and it was force is the following paragraph inside The at86rf2xx datasheets: "Using FORCE_PLL_ON to interrupt an TX_ARET transaction, it is recommended to check register bits [7:5] of register address 0x32 for value 0. If this value is different, TRX_CMD sequence FORCE_TRX_OFF shall be used immediately followed by TRX_CMD sequence PLL_ON. This performs a state transition to PLL_ON." The meaning is here "to interrupt an TX_ARET transaction" in case of trx_end interrupt the "TX_ARET transaction" is already done and we don't interrupt the "TX_ARET transaction" by doing the change to TX_ON (PLL_ON) here. Additional I changed the force change to normal TX_ON which seems to work here.
