| Summary | 0005161: Add VLCD supply only for J2 pin 1-2 not for PUs or supply voltage for GPIO Expander | ||||
| Description | It is better to directly connect VLCD from J1 to J2 pin 1 and 2. From software side we want to have the power supply switchable for the display. IO Expander can be connected directly to 3.3 V, but should be switched with VLCD. If the 5 V is interesting for we can add a circuit were VLCD can control either the 3.3V or 5V for J2 Pin 1/2, maybe with a transistor circuit. Check for PCoreMX7ULP if the used are all with level 3.3 V, because there is also pins which only have level 1.8 V. | ||||
