In this case, + - If using MCB1700 board: ADC is configured to convert signal on channel 2 + - If using IAR-LPC1768-KS board: ADC is configured to convert signal on channel 5 + DMA channel 0 was configured in this example. + The ADC conversion rate is 200KHz. A fully A fully accurate conversion requires 65 of these clocks. + So ADC clock = 200KHz * 65 = 13MHz. + Note that maximum ADC clock input is 13MHz. + + After start ADC operation, polling "DONE" bit. If "DONE" bit is set, store ADC converted data in "adc_value" + and display this data via UART0 and re-start ADC for next conversion. + + Turn potentiometer to change ADC signal input. + +@Directory contents: + \EWARM: includes EWARM (IAR) project and configuration files + \Keil: includes RVMDK (Keil)project and configuration files + + lpc17xx_libcfg.h: Library configuration file - include needed driver library for this example + makefile: Example's makefile (to build with GNU toolchain) + adc_polling_test.c: Main program + +@How to run: + Hardware configuration: + This example was tested on: + Keil MCB1700 with LPC1768 vers.1 + These jumpers must be configured as following: + - VDDIO: ON + - VDDREGS: ON + - VBUS: ON + - AD0.2: ON + - Remain jumpers: OFF + IAR LPC1768 KickStart vers.A + These jumpers must be configured as following: + - PWR_SEL: depend on power source + - DBG_EN : ON + - Remain jumpers: OFF + + Serial display configuration: (e.g: TeraTerm, Hyperterminal, Flash Magic...) + 115200bps + 8 data bit + No parity + 1 stop bit + No flow control + + Running mode: + This example can run on RAM/ROM mode. + + Note: If want to burn hex file to board by using Flash Magic, these jumpers need + to be connected: + - MCB1700 with LPC1768 ver.1: + + RST: ON + + ISP: ON + - IAR LPC1768 KickStart vers.A: + + RST_E: ON + + ISP_E: ON + + (Please reference "LPC1000 Software Development Toolchain" - chapter 4 "Creating and working with + LPC1000CMSIS project" for more information) + + Step to run: + - Step 1: Choose correct working board by uncomment correct defined board in adc_polling_test.c file + + If using MCB1700 board, uncomment "#define MCB_LPC_1768" + + If using IAR-LPC1768-KS board, uncomment "#define MCB_LPC_1768" + (Should not uncomment both symbols at the same time) + - Step 2: Build example. + - Step 3: Burn hex file into board (if run on ROM mode) + - Step 4: Connect UART0 on this board to COM port on your computer + - Step 5: Configure hardware and serial display as above instruction + - Step 6: Run example, turn potetiometer and observe data on serial display + + (Pls see "LPC17xx Example Description" document - chapter "Examples > ADC > Polling" + for more details) + +@Tip: + - Open \EWARM\*.eww project file to run example on IAR + - Open \RVMDK\*.uvproj project file to run example on Keil \ No newline at end of file
