Help Map pins from LPC1768 to nRF51DK
Hi, I have purchased a Nordic nRF51DK which works perfectly. Suddenly I purchased an EaEpaper and start to follow this tutorial http://developer.mbed.org/users/dreschpe/code/EaEpaper/wiki/Homepage#technology to map it to my board. The problem is that I can't map all the pins from LPC1768 to nRF51DK. I want to write the firmware for this awesome EaPaper screen also for the Nordic development kit but I am new to electronics and I can't fully understand all ports mappings. I am almost done but I miss few ports.
This is what I have accomplished so far
Mapping
--------------------------------------------------------- | Screen | LPC1768 | nRF51DK | TYPE | --------------------------------------------------------- | 1 GND | GND | GND | GND | --------------------------------------------------------- | 2 3V3 | VOUT | VDD | 3.3 --------------------------------------------------------- | 3 SCK | P7 | P29 | SCK --------------------------------------------------------- | 4 MOSI | P5 | P25 | MOSI --------------------------------------------------------- | 5 MISO | P6 | P28 | MISO --------------------------------------------------------- | 6 SSEL | P8 | --- | GPIO --------------------------------------------------------- | 7 BUSY | P13 | --- | GPIO --------------------------------------------------------- | 8 BORDER | P10 | --- | GPIO --------------------------------------------------------- | 9 SCL | P27 | P7 | SCL --------------------------------------------------------- |10 SDA | P28 | P30 | SDA --------------------------------------------------------- |11 PWM | P26 | --- | PWM --------------------------------------------------------- |12 RESET | P12 | --- | GPIO --------------------------------------------------------- |13 POWER | P9 | --- | GPIO --------------------------------------------------------- |14 DISC | P11 | --- | GPIO ---------------------------------------------------------
I have two questions to complete my mapping and re-write the firmware for the EaEpaper for nRF51DK:
- What is a GPIO port?
- What is a PWM port?
- Does the nRF51DK expose 3.3 volt on VDD or are they all 5 volts?
I have also included the schema of nRF51DK
and LPC1768
