MGP is right, you can't use such displays with ldmicro because it requires fine PWM control, which is not possible with ldmicro.
BUT, you can do the same with chained 7-Segment displays controled by CD4094 shift registers, using SPI to drive the chain.
look at:
https://wiki.analog.com/univer...utorial-digital-shift-register
Data= SPI_MOSI
Clock= SPI_CLK
Strobe= Vcc
Displays (CD4094) can be chained using QS ouput of one register as Data output for the next one.
One byte sent via SPI corresponds to one display.
I Tested it successfully in the past.
