    LaunchCAN?

    Sorry I am pretty bad at coming up with catchy names. Anyways, my proposal at the moment involves a "double" booster size of 100x50mm. Which will allow it to sit nicely in a 1455C case from Hammond as well. It will have properly broken out headers for LaunchPad Booster packs. Anyways some of the initial specifications I want on the board: [*:vili5prf]TI MSP430G2553 TSSOP-28 (or using headers to a LP) (might need something "bigger"?) [*:vili5prf]Microchip MCP2515 CAN Bus Controller aka "SPI<->CAN Bridge" [*:vili5prf]TI SN65HVD235 CAN Transceiver w/Auto-Baud Loop Back check

    Ethernet Booster Pack

    Hello Rob, very good. This PCB looks briliant. :thumbup: Nevertheless - the PHY signals are critical. I'm sure it will work, but maybe I can try an improvement on schematic and PCB layout. There are some small things that can be improved between W5200 and MagJack. Maybe you can send me your eagle lbr, sch and brd files -I'll send back my version and you decide. I'm actual working on an official WIZnet.lbr (all parts in one lbr) so I can also crosscheck your footprint. As this is my first posting here I like to introduce myselfe. I'm Joachim, WIZnet member & FAE in Europe an

  3. nrf24L01.h Contains command and register address definitions. nrf24L01.c Contains functions (tx not tested but should work, rx not tested) regs.h Contains settings for the MSP430 and the nrf24L01 main.c - Demo main program code Apparently the nrf24L01 can take a pules on CS without any delay. If any one runs into a problem with this do tell. The delay from PWR_UP being written to CE going high is very crucial. If not observed, the nrf24L01 will not work. Also by the looks of it the nrf24L01 can take 16Mbps SPI. I don't have a logic analyzer to test this, but my code se

    All required parts are laid out. The only things left to do are LDO and opto. I will finish it up tonight and post it for comments before sending off to Seeed. Any suggestions on LDO and opto? W5200 needs <200mA, LP probably <50mA, 250mA LDO should do the trick, but I am thinking 500mA would be the best. There is just enough space left to fit two 6 pin opto's, one dual 8 pin, or two or three 4 pin SOICs. Should I even bother?

  5. Sorry for the delay in sending the international orders. I had to figure out another way on how to package and send them without them being damaged as well not costing over $5-7 in postage alone. Most small orders where sent out around April 10th, and the large orders (zeke, xpg, krzyk2) have been sent today. Again, sorry for delaying receiving your red shiny boards and any inconvenience this may have caused. Let me know if there is anything i can do for you. They should arrive in less than week. Regards, Matthew

  6. I do it like this: In your project directory (where your sources and binary are), have a file called .gdbinit with the following contents: target remote localhost:2000 monitor reset halt load On one terminal, start MSPDebug like so: mspdebug rf2500 gdb This starts up MSPDebug in GDB proxy mode -- on one end, there is a GDB server (by default on port 2000, see help gdb); on the other end, it is attached to your FET (change rf2500 to the actual FET driver you are using). On an other terminal, assuming you are in your project's directory and your binary is called main.elf,

  7. In case anybody is having trouble with changing the solder jumpers to switch the board to support the g2553. SJ4 -> change to VDD (pulls BS0 high for 4 wire SPI) SJ3 -> change to P1.7 (moves SDIN to USCI SIMO) SJ6 -> change to P2.2 (moves D/C to GPIO) this should help...
