Tom Coxon
Test of Embedded Artists LPCXpresso baseboard ethernet, SD card, audio and OLED display facilities. The program displays the day, date and time on the baseboard OLED and sounds the Big Ben chimes on the hour and quarter hour. On initial startup the program checks that the mbed clock is set and that the chime wav files can be accessed on the SD card. If not it asks to be connected to the internet to obtain the current time and to download the wav files to the SD card.
Dependencies: EthernetNetIf NTPClient_NetServices mbed EAOLED

| tom_coxon | 0:f61e8db0570d | 3 | Just for fun this turns the Embedded Artists LPCXpresso baseboard into a Big Ben substitute. |
| tom_coxon | 0:f61e8db0570d | 4 | |
| tom_coxon | 0:f61e8db0570d | 5 | Well OK it is a little smaller and the sound is a little tinnier than the real thing but it works. |
| tom_coxon | 0:f61e8db0570d | 6 | |
| tom_coxon | 0:f61e8db0570d | 7 | This pulls together the following test programs for the Embedded Artists LPCXpresso baseboard: |
| tom_coxon | 0:f61e8db0570d | 8 | |
| tom_coxon | 0:f61e8db0570d | 9 | EA_InternetClock (now superseded by this program) |

| tom_coxon | 0:f61e8db0570d | 11 | EA_DownloadToSD |
| tom_coxon | 0:f61e8db0570d | 12 | |
| tom_coxon | 0:f61e8db0570d | 13 | The program displays the day, date and time on the baseboard OLED and sounds the Big Ben chimes |
| tom_coxon | 0:f61e8db0570d | 14 | on the hour and quarter hour. |
| tom_coxon | 0:f61e8db0570d | 15 | |
| tom_coxon | 0:f61e8db0570d | 16 | On initial startup the program checks that the mbed clock is set and that the wav files can be accessed |
| tom_coxon | 0:f61e8db0570d | 17 | on the SD card. If not it asks to be connected to the internet to obtain the current time and to download |
| tom_coxon | 0:f61e8db0570d | 18 | the wav files to the SD card. |
| tom_coxon | 0:f61e8db0570d | 19 | |
| tom_coxon | 0:f61e8db0570d | 20 | The wav file player works with uncompressed wav files with 8 or 16 bit sample sizes. |
| tom_coxon | 0:f61e8db0570d | 21 | |
| tom_coxon | 0:f61e8db0570d | 22 | Setup of the baseboard: |
| tom_coxon | 0:f61e8db0570d | 23 | |
| tom_coxon | 0:f61e8db0570d | 24 | Please set all jumpers on board to the default case except for |
| tom_coxon | 0:f61e8db0570d | 25 | the following: |
| tom_coxon | 0:f61e8db0570d | 26 | |
| tom_coxon | 0:f61e8db0570d | 27 | Audio setup: |
| tom_coxon | 0:f61e8db0570d | 28 | |
| tom_coxon | 0:f61e8db0570d | 29 | 1. Insert a jumper in J31 to connect signal PIO1_2 to the low |
| tom_coxon | 0:f61e8db0570d | 30 | pass filer as described in section 4.7.2. of base board users |
| tom_coxon | 0:f61e8db0570d | 31 | guide. |
| tom_coxon | 0:f61e8db0570d | 32 | |
| tom_coxon | 0:f61e8db0570d | 33 | 2. Insert three jumpers in J33 to connect PIO3_0, PIO3_1 and |
| tom_coxon | 0:f61e8db0570d | 34 | PIO3_2 to control the amplifier as described in section 4.8 |
| tom_coxon | 0:f61e8db0570d | 35 | of base board users guide. |
| tom_coxon | 0:f61e8db0570d | 36 | |
| tom_coxon | 0:f61e8db0570d | 37 | 3. Insert a jumper in J32 and remove any from J34 to use the |
| tom_coxon | 0:f61e8db0570d | 38 | internal speaker as described in section 4.8 |
| tom_coxon | 0:f61e8db0570d | 39 | of base board users guide. |
| tom_coxon | 0:f61e8db0570d | 40 | |
| tom_coxon | 0:f61e8db0570d | 41 | SD Card setup: |
| tom_coxon | 0:f61e8db0570d | 42 | |
| tom_coxon | 0:f61e8db0570d | 43 | 4. Insert all five jumpers in J39 as described in section 4.3.3 |
| tom_coxon | 0:f61e8db0570d | 44 | of base board users guide. |
| tom_coxon | 0:f61e8db0570d | 45 | |
| tom_coxon | 0:f61e8db0570d | 46 | 5. Remove jumper marked "A" in J55 In order to connect PIO1_11 |
| tom_coxon | 0:f61e8db0570d | 47 | to CS signal of J40 (the SPI-SSEL signal) as described in section 4.3.3 |
| tom_coxon | 0:f61e8db0570d | 48 | of base board users guide. |
| tom_coxon | 0:f61e8db0570d | 49 | |
| tom_coxon | 0:f61e8db0570d | 50 | OLED setup: |
| tom_coxon | 0:f61e8db0570d | 51 | |
| tom_coxon | 0:f61e8db0570d | 52 | 1. The LCPXpresso board does not provide the data/command signal to the mbed. |
| tom_coxon | 0:f61e8db0570d | 53 | To provide this signal please connect a jumper wire from PIO2_7 of baseboard mbed socket |
| tom_coxon | 0:f61e8db0570d | 54 | (empty 2nd hole below mbed pin 21) to to PIO2_5 (on J6 right side ninth hole from bottom). |
