====== MIOS Pin List ====== This list gives you an oversight over the pin usage of MIOS. ^ Name ^ Class ^ Core Port:Pin ^ PIC Pin # ^ Direction ^ Additional Information | | RA0 | A | J5:A0 | 2 | Input | analog pin| | RA1 | A | J5:A1 | 3 | Input | analog pin| | RA2 | A | J5:A2 | 4 | Input | analog pin| | RA3 | A | J5:A3 | 5 | Input | analog pin| | RA5 | A | J5:A4 | 7 | Input | analog pin| | RE0 | A | J5:A5 | 8 | Input | analog pin| | RE1 | A | J5:A6 | 9 | Input | analog pin| | RE2 | A | J5:A7 | 10 | Input | analog pin| | RA4 | K | J4:SD | 6 | Input / Output | IIC data pin SD, external 1k pull-up, can be used by an application for other purposes so long MIOS_IIC_* won't be called| | RC0 | B | J6:RC / J7:RC | 15 | Output | used to address the AIN multiplexers or the MF module. In both cases driven by an interrupt service routine. | | RC1 | B | J6:SC / J7:SC | 16 | Output | used to address the AIN multiplexers or the MF module. In both cases driven by an interrupt service routine. | | RC2 | D | J7:SO | 18 | Output | used as serial output to the MF module, driven by an interrupt service routine. | | RC3 | C | J6:SI / J10:PWM | 17 | Output | used to address the AIN multiplexers, driven by an interrupt service routine / SID PWM. This pin is stuffed with an external 10k pull-up which could be useful for an application which uses this pin as input| | RD0 | E | J8:SO | 19 | Output | serial output to the DOUT chain, driven by an interrupt service routine if MIOS_SRIO active| | RD1 | E | J9:SI | 20 | Input | serial input to the DIN chain, used by an interrupt service routine if MIOS_SRIO active| | RD2 | F | J8:RC / J9:RC | 21 | Output | serial latch output, used by an interrupt service routine if MIOS_SRIO active| | RD3 | F | J8:SC / J9:SC / J10:SC | 22 | Output | serial clock output, used by an interrupt service routine if MIOS_SRIO active / SID SC| | RC4 | G | J10:RC | 23 | Output | SID RC / free for applications without restrictions if second CLCD not used| | RC5 | G | J10:SO | 24 | Output | SID SO / free for applications without restrictions| | RD4 | E | J14 | 27 | Output | touch sensor strobe signal, used by an interrupt service routine if MIOS_SRIO active and TS_Sensitivity > 0| | RD5 | H | J4:SC / J10:MD / J15:RS | 28 | Output | clock output to IIC / SID MD / address signal to LCD | | RD6 | H | J10:MU / J15:RW | 29 | Output | SID MU / RW signal to LCD| | RD7 | I | J15:E | 30 | Output | enable signal to LCD (exclusive!)| | RB0 | J | J15:D0 | 33 | Input / Output | LCD data line #0| | RB1 | J | J15:D1 | 34 | Input / Output | LCD data line #1| | RB2 | J | J15:D2 | 35 | Input / Output | LCD data line #2 / CAN Tx| | RB3 | J | J15:D3 | 36 | Input / Output | LCD data line #3 / CAN Rx| | RB4 | J | J15:D4 | 37 | Input / Output | LCD data line #4| | RB5 | J | J15:D5 | 38 | Input / Output | LCD data line #5| | RB6 | J | J15:D6 | 39 | Input / Output | LCD data line #6| | RB7 | J | J15:D7 | 40 | Input / Output | LCD data line #7| The pins are divided into following classes: * Class A: analog inputs, which can be optionally used as digital inputs or outputs like demonstrated in the j5_dout and j5_din example if the MIOS_AIN and MIOS_MF driver are not used * Class B: digital pin which is free for applications if neither the MIOS_AIN multiplex driver, nor the MIOS_MF driver is active Also free if MIOS_AIN doesn't run in mux mode * Class C: digital pin which is free for applications if the MIOS_AIN multiplex driver isn't active * Class D: digital pin which is free for applications if the MIOS_MF driver isn't active * Class E: digital pin which is free for an application if the MIOS_SRIO driver isn't active. Can also be shared with other devices if the application accesses the pin from an interrupt service routine or if it disables all interrupts for a short time (< 300 uS!). Touchsensor Pin. * Class F: digital pin which is free for an application if the MIOS_SRIO driver isn't active. * Class G: free pin which can be used by the application without any restrictions * Class H: digital pin which can be shared with other modules (LCD/IIC/...) Shouldn't be used from an interrupt service routine * Class I: digital pin, exclusive for LCD * Class J: digital IO pin, can be shared with the LCD data lines as IO pins so long J15:E is low (means: MIOS doesn't execute a MIOS_LCD function) Shouldn't be used from an interrupt service routine * Class K: see description See also the [[http://www.ucapps.de/mbhp/mbhp_core_v3.pdf|schematic of the MBHP_CORE]] module as reference, or this PCB layout: {{http://www.ucapps.de/mbhp/mbhp_core_v3.gif}} This table is based on the original from [[http://www.ucapps.de/mios/mios_pin_list.txt|mios_pin_list.txt]]
