List,
I try to get gpio_191 ping interrupted on panda but never succeeded. What I do is
1. set 0x410b on dpm_emu19 register to enable interrupt and wakeup
on gpio_191
2. set bit 31 to 1 on GPIO_IRQSTATUS_SET_0 register at 0x4805d034
3. set bit 31 to 1 on GPIO_IRQWAKEN_0 register at 0x4805d044
4. set bit 31 to 0 on GPIO_OE register at 0x4805d134 (output)
5. set bit 31 to 1 on GPIO_SETDATAOUT register at 0x4805d194
Then I expect I should see interrupt on GPIO_IRQSTATUS_0 register at 0x4805d02c. But nothing happens for both output and input (put pin on ground or 1,8v).
You will not get an interrupt if you are configuring the gpio as an
output (GPIO_OE[31] = 0).
