# Analog ADS1256 (SPI) | ||
|
||
Purpose: This add-on is intended to allow you to use ADS1256 SPI compatible accessories (currently in early beta). | ||
|
||
![GP2040-CE Configurator - Add-Ons ADS1219](../assets/images/gpc-add-ons-ads1256-spi.png) | ||
|
||
## Web Configurator Options | ||
|
||
:::info GPIO Pin Assignment | ||
|
||
The `SPI Block`, `Chip Select Pin` and `Data Ready Pin` are now configured in [`Configuration > Peripheral Mapping - SPI`](../web-configurator/menu-pages/03-peripheral-mapping.mdx#spi). | ||
|
||
::: | ||
|
||
- `SPI Block` - The block of SPI to use (spi0 or spi1). | ||
- `Chip Select (CS) Pin` - The GPIO pin to use for Chip Select. | ||
- `Data Ready (DRDY) Pin` - The GPIO pin to use for Data Ready. | ||
- `Analog Max` - The maximum voltage that will be used, `3.3V` and `5V` are selectable here. | ||
|
||
## Hardware | ||
|
||
### Requirements | ||
|
||
Please note that this add-on is currently in early beta and no examples of use are offered. |

# Rotary Encoders | ||
|
||
:::Note | ||
|
||
Please note that rotary encoders are currently in beta. | ||
::: | ||
|
||
Purpose: Rotary encoders allow for continuous or limited min-max pulses on specified pins. | ||
|
||
![GP2040-CE Configuration - Add-Ons Rotary Encoders](../assets/images/gpc-add-ons-rotary-encoders.png) | ||
|
||
## Web Configurator Options | ||
|
||
- `Enabled` - Enables or disables `Encoder 1` or `Encoder 2`. | ||
- `Pin A/CLK` - The `Clock` pin for the encoder. | ||
- `Pin B/DT` - The `Data` pin for the encoder`. | ||
- `Pulses/Revolutions (PPR)` - The number of puleses/revolutions on your encoder. | ||
- `Multiplier` - Use this multiplier to fine tune your encoder performance in GP2040-CE. | ||
- `Reset After (ms)` - The number of miliseconds to wait before resetting the value to `0` / `center`. | ||
- `Control Mode` - Choose how this encoder will function. | ||
- `Allow Wrap-Around` - Allows the encoder to reach an axis max and wrap-around to the axis minimum. | ||
