Posted by: HockeT in English, German, Hardware, HardwareAfter a long search I listed the following reasons in the Philips LPC2138 as the UAV brain:
- 52 MHz for fast calculations and operations
- 14 ADC channels for analog sensorics
- 2 UARTs for serial modem and GPS
- 4 I²C bus interfaces for port expanders, sensors and drivers
- PI bus interface for In System Programming, sensors and control
- Programmable in C
Key facts of the LPC2138:
- 32bit ARM7 core
- LQFP64 pack
- 32 kB static ram and 512 kB flash memory
- Two 10 bit 8 chan. ADC
- 2 32bit timer with PWM
- 2 UARTs
- 2 I²C
- SPI, SSP
- 47 5V tolerant I/Os
- with crystal up to 50 MHz
