All programs that use the GPIO module purposely delay 2 seconds to give the GPIO thread time to start up. Replace this with a semaphore: if pthread_create() doesn't error out, grab a semaphore that blocks until the GPIO thread clears it. Then check pidp8i_gpio_present to learn whether GPIO was mapped and set up. This should cut most of this 2-second delay out of the startup time. tangent added on 2017-03-19 08:06:26: Fixed in [f5c3de8341] | ||||
