Hello ! I have 16 relay module that I want to control with IOIO. I know that this is not IOIO problem, but is there anything I could do with IOIO digital i/O (or hadware).
http://www.aliexpress.com/item/2015-China-Wholesale-12V-16-Channel-Relay-Module-for-arduino-ARM-PIC-AVR-DSP-Electronic-Relay/32305996877.html I have connected this to 16 pins in IOIO and defined the pins as digital output. 11 of the relays work as expected, but 5 relays do not react to the IOIO 3.2V signal going up or down. However if I shortcut those 5 malfunction pins in relay module to ground, the relay reacts as expected ! When the relay control pin is connected to IOIO, the relay is always on, but does not go off for IOIO signal I have tried to define the digital outputs also as "open drain"-mode, but no success. Is there anything else that I could do (other than buy a new relay module) ? -- You received this message because you are subscribed to the Google Groups "ioio-users" group.
