For example USART3_TX is on PORT<strong>B</strong> pin 10 and USART1_RX is on PORT<strong>A</strong> pin 10. The mappings can be found in the <a href="http://leaflabs.com/docs/maple/gpio/#pins">Pin Mapping Mega Table</a>. </p> http://forums.leaflabs.com/topic.php?id=171#post-1106 Wed, 08 Sep 2010 09:08:32 +0000 StephenFromNYC 1106@http://forums.leaflabs.com/ <p>Wednesday September 8, 2010</p> <p>Hello,</p> <p>I am confused by the pin assignments for serial input.</p> <p>Based on the silk-screening on my Maple Rev3 (summer 2010) I thought the three serial ports used the following pins on Maple board:</p> <p>Serial1: TX1 (pin 07) RX1 (pin 08)<br /> Serial2: TX2 (pin 01) RX2 (pin 00)<br /> Serial3: TX3 (pin 29) RX3 (pin 30)</p> <p>This information is the same as file: usart.html</p> <p>However, the information appears to be different in file: \hardware\leaflabs\cores\maple\HardwareSerial.cpp</p> <blockquote><p> #define USART1_TX_PORT GPIOA_BASE<br /> #define USART1_TX_PIN 9<br /> #define USART1_RX_PORT GPIOA_BASE<br /> #define USART1_RX_PIN 10</p> <p>#define USART2_TX_PORT GPIOA_BASE<br /> #define USART2_TX_PIN 2<br /> #define USART2_RX_PORT GPIOA_BASE<br /> #define USART2_RX_PIN 3</p> <p>#define USART3_TX_PORT GPIOB_BASE<br /> #define USART3_TX_PIN 10<br /> #define USART3_RX_PORT GPIOB_BASE<br /> #define USART3_RX_PIN 11 </p></blockquote> <p>The code in HardwareSerial.cpp seems to suggest the pins are 9, 10, 2, 3, 10 (again), and 11.</p> <p>I am using Windows XP Professional SP3 and Maple IDE 0.0.6.</p> <p>Thanks!</p> <p>Stephen from NYC </p>
