====== Badger1 Flight Computer ====== ===== Badger1 is dead, long live Badger1 ===== Unfortunately Badger1 was lost to the north sea on Nova 13. After some months it was found washed up on a beach in Denmark and returned to us... {{badger1_final_fate.jpg}} **NOTE: Badger1 is about to be superseded by [[Badger2]] and needs a few hardware bodges to get it to work correctly** Eagle PCB files and firmware on the SVN server. ===== Revision History ===== ^Rev ^Notes ^ |1.0 |Initial version, never produced. | |1.1 |Few minor tweaks, PCBs produced from this revision. | ===== Images ===== {{badger-bottom.jpg?400}}{{badger-top.jpg?400}} ===== LPC Pin Assignments ===== **NOTE: these are the pin assignments before bodges** Made a note of if pins are ADCs etc, but not listed all features for every pin - just where its likely they will be needed ^Function ^Pin ^Pin name ^Notes ^ |LED1 |1 |P0.21 |active high | |LED2 |2 |P0.22 |active high | | |||| |I2C.1 (spare) |12 |P1.17 |spare | |I2C.3 (spare) |13 |P0.28/AD0.1 |" | |I2C.5 (spare) |14 |P0.29/AD0.2 |" | |I2C.6 (spare) |15 |P0.30/AD0.3 |" | |I2C.7 (I2C clk) |22 |SCL0/P0.2 |I2C port 0 clock | |I2C.9 (I2C data) |26 |SDA0/P0.3 |I2C port 0 data | | |||| |LASSEN.1 (TXA) |21 |RXD0/P0.1 |serial GPS data into ARM UART 0 | |LASSEN.3 (RXA) |19 |TXD0/P0.0 |data out from ARM UART 0 to GPS | |LASSEN.4 (PPS) |9 |P0.25 |pulse per second input | | |||| |GSM.20 (TXD) |33 |TXD1/P0.8 |serial data out from ARM UART1 to GSM | |GSM.37 (RXD) |34 |RXD1/P0.9 |serial data from GSM into ARM UART1 | |GSM.36 (DCD) |44 |P1.21 | | |GSM.33 (DSR) |48 |P1.20 | | |GSM.23 (RESET) |40 |P1.22 | | |GSM.17 (ON/OFF) |36 |P1.23 | | | |||| |**Maxim SPI temperature sensor DS1626/DS1762**|||| |TEMP.3 (/RST) |16 |P1.16 |SPI chip select - high = selected | |TEMP.2 (CLK) |27 |SCK0/P0.4 |ARM SPI0 clock | |TEMP.1 (DO) |29 |MISO0/P0.5 |ARM SPI0 data input | | |||| |MMC.1 (CS) |38 |P0.12 | | |MMC.2 (DI) |30 |MOSI0/P0.6 |ARM SPI0 data output | |MMC.5 (SCK) |27 |SCK0/P0.4 |ARM SPI0 clock | |MMC.7 (DO) |29 |MISO0/P0.5 |ARM SPI0 data input | | |||| |**LIS3LV02 SPI 3-axis accelerometer**|||| |ACCN.9 (SDO) |29 |MISO0/P0.5 |ARM SPI0 data input | |ACCN.10 (SDI) |30 |MOSI0/P0.6 |ARM SPI0 data output | |ACCN.12 (SCL) |27 |SCK0/P0.4 |ARM SPI0 clock | |ACCN.13 (CS) |31 |SSEL0/P0.7 |ARM SPI0 chip select | | |||| |SPARE1.1 |47 |P0.17 | | |SPARE1.2 |46 |P0.16 | | |SPARE1.3 |45 |P0.45 | |
