    Running out of UDBs too early

    daniel.greenwald

      I'm trying to fit as much as I possibly can into a PSoC4 - I want 2 quadrature decoders, 6 pwm outputs, and 3 serial modules

         

      By putting two of the serials in to SCBs and the 2 quadrature decoders + 2 PWMs into TCPWM blocks, it just leaves enough for the remaining serial and PWMs in UDBa

         

      I can put in 1 x 8 bit double output PWM modules with no trouble, giving me a total of 4 pwm outputs. When I build, this reports enough resources remaining to add another PWM. However, when I try, it says "5 UDBs required" :(

         

      Can any one shed any light on this?
