digitalWrite issue (conflict with analogWrite?) #52
Description
hello,
this code throws an error on all my BBblack (since bonescript 0.7.0 update) :
b.detachInterrupt('P9_29');`
b.pinMode('P9_29', b.OUTPUT);
b.digitalWrite('P9_29', b.LOW);
b.detachInterrupt('P9_21');
b.pinMode('P9_21', b.OUTPUT);
b.digitalWrite('P9_21', b.LOW); // <-------- here
the second b.digitalWrite throws this error :
analogWrite: P9_21 requires pwm EHRPWM0B but it is already in use by P9_29
it seems to be caused by this portion of code in "/usr/local/lib/node_modules/bonescript/src/index.js" in digitalWrite function :
var gpioEnabled = (7 == f.getPinMode(pin).mux); //check whether pin set as gpio
if (!gpioEnabled) {
winston.debug([pin.key, value] + ' set as ANALOG_OUTPUT modifying duty cycle according to value');
f.analogWrite(pin, value, 2000, myCallback); //write duty cycle as per value
return (true);
}
because if we inspect "f.getPinMode(pin)" it shows no mux property :
for P9_29 :
`{ pin: 'P9_29',
name: 'SPI1_D0',
options:
[ 'mcasp0_fsx',
'ehrpwm0B',
'NA',
'spi1_d0',
'mmc1_sdcd',
'pr1_pru0_pru_r30_1',
'pr1_pru0_pru_r31_1',
'gpio3_15' ],
gpio: { active: true, direction: 'out', allocated: true } }`
for P9_21 :
`{ pin: 'P9_21',
name: 'UART2_TXD',
options:
[ 'spi0_d0',
'uart2_txd',
'i2c2_scl',
'ehrpwm0B',
'pr1_uart_rts_n',
'pr1_edio_latch_in',
'EMU3',
'gpio0_3' ],
gpio: { active: true, direction: 'out', allocated: true } }`
if I comment this code it works :
if (!gpioEnabled) {
winston.debug([pin.key, value] + ' set as ANALOG_OUTPUT modifying duty cycle according to value');
f.analogWrite(pin, value, 2000, myCallback); //write duty cycle as per value
return (true);
}
