20X2 - Servos & HSERIN

Hi Guys.

Just a quick question.

I am looking to put together a serial servo controller board. Ideally it would control 8 servos and multiple modules can be run from the same serial commnication comming from my master PICAXE. Each module would have jumpers to select the starting address of the servos

I intend to use HSERIN to recieve the data because as I understand software serial interferes with the SERVO command.

Am I correct in saying that on a 20X2 i can only control 7 servos if i am also using HSERIN due to pin conflicts? Is there a SIMPLE way round this?

Thanks

Welcome to the PICAXE forum.

The simplest way around any shortage of I/O is to use multiple PICAXE. If one PICAXE would ideally control 8 servos, then two could control four each. This would likely fit in with a modular serial controlled system; the main controller shouldn't particularly care how the servo controllers are divided up.

Alternatively, choose a PICAXE which allows 8 servos to be controlled while allowing the use of HSERIN. The 28X2 I believe would.
