Therfore the columns of Button Port A were swapped, to have GND on the outer column of each Button Port and the I/O pin on the inner column of each button port. ![]() #Doss asimom user manual english driver#With the appearance of the first Power Driver and Breakout Extension boards, this proved to be more unintuitive than a symmetrical layout which would allow for symmetrical cable routing. In version 3.3 there was an important change: In the previous versions the pinout of Button Ports A and B (the 40 pin headers) was laid out identically as described in the previous chapter: Left column of each button port is I/O pins, right column is according GNDs. V3.2 shows the pinout of the Button Ports, which is valid for versions 3.0 through 3.2: Left column of each button port is I/O pins, right column is according GND. There is no photo of V3.0, but there are functional differences compared to V3.1. Starting from version 3.0 all modules are compatible with the current firmware. Therefore it has been changed with PCB V3.7. However, it has the disadvantage that on a connected flat ribbon cable neighbouring signals are nested with each other, which can reduce signal integrity and prohibits simple mechanical splitting of such a flat cable into channels. This pinout was used up to board revision V3.6 because it looked more intuitive for the user. So, for analog input 0, the connections would be: Pin The center pin is connected to the wiper (center pin of the pot), the outer pins are connected to the end terminals (= outer pins of the pot).
