<> | 144:ef7eb2e8f9f7 | 1 | mbed port to NXP LPC43xx |
<> | 144:ef7eb2e8f9f7 | 2 | ======================== |
<> | 144:ef7eb2e8f9f7 | 3 | Updated: 07/11/14 |
<> | 144:ef7eb2e8f9f7 | 4 | |
<> | 144:ef7eb2e8f9f7 | 5 | The NXP LPC43xx microcontrollers includes multiple Cortex-M cores in a single |
<> | 144:ef7eb2e8f9f7 | 6 | microcontroller package. This port allows mbed developers to take advantage |
<> | 144:ef7eb2e8f9f7 | 7 | of the LPC43xx in their application using APIs that they are familiar with. |
<> | 144:ef7eb2e8f9f7 | 8 | Some of the key features of the LPC43xx include: |
<> | 144:ef7eb2e8f9f7 | 9 | |
<> | 144:ef7eb2e8f9f7 | 10 | * Dual core ARM Cortex-M4/M0 both capable of up to 204 MHz |
<> | 144:ef7eb2e8f9f7 | 11 | * Up to 264 KB SRAM, 1 MB internal flash |
<> | 144:ef7eb2e8f9f7 | 12 | * Two High-speed USB 2.0 interfaces |
<> | 144:ef7eb2e8f9f7 | 13 | * Ethernet MAC |
<> | 144:ef7eb2e8f9f7 | 14 | * LCD interface |
<> | 144:ef7eb2e8f9f7 | 15 | * Quad-SPI Flash Interface (SPIFI) |
<> | 144:ef7eb2e8f9f7 | 16 | * State Configurable Timer (SCT) |
<> | 144:ef7eb2e8f9f7 | 17 | * Serial GPIO (SGPIO) |
<> | 144:ef7eb2e8f9f7 | 18 | * Up to 164 GPIO |
<> | 144:ef7eb2e8f9f7 | 19 | |
<> | 144:ef7eb2e8f9f7 | 20 | The NXP LPC18xx is a single core Cortex-M3 implementation that is compatible |
<> | 144:ef7eb2e8f9f7 | 21 | with the LPC43XX for cost-sensitive applications not requiring multiple cores. |
<> | 144:ef7eb2e8f9f7 | 22 | |
<> | 144:ef7eb2e8f9f7 | 23 | mbed port to the LPC43XX - Micromint USA <support@micromint.com> |
<> | 144:ef7eb2e8f9f7 | 24 | |
<> | 144:ef7eb2e8f9f7 | 25 | Compatibility |
<> | 144:ef7eb2e8f9f7 | 26 | ------------- |
<> | 144:ef7eb2e8f9f7 | 27 | * This port has been tested with the following boards: |
<> | 144:ef7eb2e8f9f7 | 28 | Board MCU RAM/Flash |
<> | 144:ef7eb2e8f9f7 | 29 | Micromint Bambino 200 LPC4330 264K SRAM/4 MB SPIFI flash |
<> | 144:ef7eb2e8f9f7 | 30 | Micromint Bambino 200E LPC4330 264K SRAM/8 MB SPIFI flash |
<> | 144:ef7eb2e8f9f7 | 31 | Micromint Bambino 210 LPC4330 264K SRAM/4 MB SPIFI flash |
<> | 144:ef7eb2e8f9f7 | 32 | Micromint Bambino 210E LPC4330 264K SRAM/8 MB SPIFI flash |
<> | 144:ef7eb2e8f9f7 | 33 | |
<> | 144:ef7eb2e8f9f7 | 34 | * CMSIS-DAP debugging is implemented with the Micromint Bambino 210/210E. |
<> | 144:ef7eb2e8f9f7 | 35 | To debug other LPC4330 targets, use a JTAG. The NXP DFU tool can be used |
<> | 144:ef7eb2e8f9f7 | 36 | for flash programming. |
<> | 144:ef7eb2e8f9f7 | 37 | |
<> | 144:ef7eb2e8f9f7 | 38 | * This port should support NXP LPC43XX and LPC18XX variants with a single |
<> | 144:ef7eb2e8f9f7 | 39 | codebase. The core declaration specifies the binaries to be built: |
<> | 144:ef7eb2e8f9f7 | 40 | mbed define CMSIS define MCU Target |
<> | 144:ef7eb2e8f9f7 | 41 | __CORTEX_M4 CORE_M4 LPC43xx Cortex-M4 |
<> | 144:ef7eb2e8f9f7 | 42 | __CORTEX_M0 CORE_M0 LPC43xx Cortex-M0 |
<> | 144:ef7eb2e8f9f7 | 43 | __CORTEX_M3 CORE_M3 LPC18xx Cortex-M3 |
<> | 144:ef7eb2e8f9f7 | 44 | These MCUs all share the peripheral IP, common driver code is feasible. |
<> | 144:ef7eb2e8f9f7 | 45 | Yet each variant can have different memory segments, peripherals, etc. |
<> | 144:ef7eb2e8f9f7 | 46 | Plus, each board design can integrate different external peripherals |
<> | 144:ef7eb2e8f9f7 | 47 | or interfaces. A future release of the mbed SDK and its build tools will |
<> | 144:ef7eb2e8f9f7 | 48 | support specifying the target board when building binaries. At this time |
<> | 144:ef7eb2e8f9f7 | 49 | building binaries for different targets requires an external project or |
<> | 144:ef7eb2e8f9f7 | 50 | Makefile. |
<> | 144:ef7eb2e8f9f7 | 51 | |
<> | 144:ef7eb2e8f9f7 | 52 | * No testing has been done with LPC18xx hardware. |
<> | 144:ef7eb2e8f9f7 | 53 | |
<> | 144:ef7eb2e8f9f7 | 54 | Notes |
<> | 144:ef7eb2e8f9f7 | 55 | ----- |
<> | 144:ef7eb2e8f9f7 | 56 | * On the LPC43xx the hardware pin name and the GPIO pin name are not the same, |
<> | 144:ef7eb2e8f9f7 | 57 | requiring different offsets for the SCU and GPIO registers. To simplify logic |
<> | 144:ef7eb2e8f9f7 | 58 | the pin identifier encodes the offsets. Macros are used for decoding. |
<> | 144:ef7eb2e8f9f7 | 59 | For example, P6_11 corresponds to GPIO3[7] and is encoded/decoded as follows: |
<> | 144:ef7eb2e8f9f7 | 60 | |
<> | 144:ef7eb2e8f9f7 | 61 | P6_11 = MBED_PIN(0x06, 11, 3, 7) = 0x032C0067 |
<> | 144:ef7eb2e8f9f7 | 62 | |
<> | 144:ef7eb2e8f9f7 | 63 | MBED_SCU_REG(P6_11) = 0x4008632C MBED_GPIO_PORT(P6_11) = 3 |
<> | 144:ef7eb2e8f9f7 | 64 | MBED_GPIO_REG(P6_11) = 0x400F4000 MBED_GPIO_PIN(P6_11) = 7 |
<> | 144:ef7eb2e8f9f7 | 65 | |
<> | 144:ef7eb2e8f9f7 | 66 | * Pin names use multiple aliases to support Arduino naming conventions as well |
<> | 144:ef7eb2e8f9f7 | 67 | as others. For example, to use pin p21 on the Bambino 210 from mbed applications |
<> | 144:ef7eb2e8f9f7 | 68 | the following aliases are equivalent: p21, D0, UART0_TX, COM1_TX, P6_4. |
<> | 144:ef7eb2e8f9f7 | 69 | See the board pinout graphic and the PinNames.h for available aliases. |
<> | 144:ef7eb2e8f9f7 | 70 | |
<> | 144:ef7eb2e8f9f7 | 71 | * The LPC43xx implements GPIO pin and group interrupts. Any pin in the 8 32-bit |
<> | 144:ef7eb2e8f9f7 | 72 | GPIO ports can interrupt (LPC4350 supports up to 164). On group interrupts a |
<> | 144:ef7eb2e8f9f7 | 73 | pin can only interrupt on the rising or falling edge, not both as required |
<> | 144:ef7eb2e8f9f7 | 74 | by the mbed InterruptIn class. Also, group interrupts can't be cleared |
<> | 144:ef7eb2e8f9f7 | 75 | individually. This implementation uses pin interrupts (8 on M4/M3, 1 on M0). |
<> | 144:ef7eb2e8f9f7 | 76 | A future implementation may provide group interrupt support. |
<> | 144:ef7eb2e8f9f7 | 77 | |
<> | 144:ef7eb2e8f9f7 | 78 | * The LPC3xx PWM driver uses the State Configurable Timer (SCT). The default |
<> | 144:ef7eb2e8f9f7 | 79 | build (PWM_MODE=0) uses the unified 32-bit times. Applications that use PWM |
<> | 144:ef7eb2e8f9f7 | 80 | and require other SCT uses can use the dual 16-bit mode by changing PWM_MODE |
<> | 144:ef7eb2e8f9f7 | 81 | when building the library. |
