- usb.sch: cleaned up programming/auxiliary/LED signals
- usb.sch: swapped LED and nRST_RF (tracking the layout)
- atusb.brd: updated for corrected netlist
- atusb.brd: moved date code which overlapped with traces
- atusb.brd: reduced front RF and power ground zones to avoid ground
fill between transceiver pads
- atusb.brd: added ground traces around crystal to widen ground zone
- atusb.pro, atusb.cmp: updated for ATmega32U2-based design
- usb.sch: rearranged LED, nRST_RF, and SLP_TR, to make layout easier
- atusb.brd: redid layout for the ATmega32U2-based design
- usb.sch: renumbered test points for serial programming
- usb.sch: moved everything down to make room on top
- usb.sch: moved description of pad placement near the pads
- usb.sch: added footprint of U1
- atusb.pro (LibName5): changed from c8051f326 to atmega8u2
- atrf.sch: export CLKM and added filter for 8 MHz clock
- atusb.sch: connect CLK between RF and USB side
- usb.sch: changed design frim C8051F326 to ATmega32U2 (needs cleanup)
Settings according to
http://www.nxp.com/documents/mounting_and_soldering/AN10365.pdf
- atben.pro, atben.brd, atusb.pro, atusb.brd: set solder mask clearance
to 50 um (copper-defined pads)
- atben.pro, atben.brd, atusb.pro, atusb.brd: set solder paste clearance
to 25 um
- atusb.brd: moved component references for proper printing on silk screen
- atusb.brd: moved component values for easy display (do not print on
silk screen !)
- atusb.brd, atusb.cmp: changed all 0402-M to the new 0402
- atusb.brd, atusb.cmp: changed 0603-M to the new 0603
- atusb.brd: updated layout for component changes
- at86rf230.h (REG_BATMON): address is 0x11, not 0x10
- at86rf230.h (TRX_CMD_MASK): width is 5 bits, not 3
- at86rf230.h (CLKM_CTRL_MASK): width is 3 bits, not 2
- at86rf230.h (PA_EXT_EN, IRQ_2_EXT_EN, TX_AUTO_CRC_ON_231): shifted by one
bit
- at86rf230.h (RX_BL_CTRL, AACK_DIS_ACK): added missing field
- at86rf230.h: added fields PA_BUF_LT and PA_LT
- at86rf230.h (ANT_DIV): added fields of this register
- at86rf230.h (NATMON_VTH_SHIFT, NATMON_VTH_MASK): corrected typo
- atrf.sch: replaced the AT86RF230 with the AT86RF231
- atusb.sch, usb.sch, atrf.sch: removed TST signal
- atrf.sch: grounded former TST pin
- atusb.brd: updated for TST removal
- atusb.brd: increased space between SLP_TR and nRST_RF vias
- atusb.brd: connect U2 pin 6 to ground pad
- atusb.sch, usb.sch, atrf.sch, atusb.brd: changed version to 20110104
- atusb.brd: increased RF ground zone by 150 mil in an attempt to reduce
interferences between the the antenna and the rest of the circuit
- atusb.brd: added more vias around and inside the RF ground zone
- atusb.brd: set version to 20110102
Traces leaving a pad on the side may invite solder bridges to "false pads"
exposed at the edges of the chip, with unknown consequences.
- atusb.brd: make trace from P0.0 (IRQ_RF) leave pad at the front, not
at the side
- atusb.brd: make trave from P0.7 (SCLK) leave pad at front, not at the
side
- atusb.brd: nRST may need an external pull-up to VDD. Added via to bring
nRST and VDD within reach (pull-up suggested by Joerg Reisenweber)
- atusb.brd: increased version to 20101229
