+# AS5145 SimpleFOC driver
+
+SSI protocol driver for the AMS AS5145 magnetic encoder. Any of the A, B or H variants should work. AS5045 encoders should also be supported.
+
+Only angle reading is supported, might get to the status bits at a later time.
+The SSI protocol is "emulated" using the SPI peripheral.
+
+Tested with AS5145A on STM32G491 so far.
+
+## Hardware setup
+
+Wire the sensor's data (DO) line to the MISO (CIPO) pin, nCS, SCK as normal. Leave the MOSI pin unconnected.
+
+## Software setup
+
+```
+#include <Arduino.h>
+#include <SimpleFOC.h>
+#include <SimpleFOCDrivers.h>
+#include "encoders/as5145/MagneticSensorAS5145.h"
+
+MagneticSensorAS5145 sensor;
+SPIClass spi_ssi(PB15, PB14, PB13, PB12);
+
+long ts;
+
+void setup() {
+  Serial.begin(115200);
+  while (!Serial) ;
+  delay(2000);
+
+  Serial.println("Initializing sensor...");
+
+  spi_ssi.begin();
+  sensor.init(&spi_ssi);
+
+  Serial.println("Sensor initialized.");
+
+  ts = millis();
+}
+
+void loop() {
+  sensor.update();
+  if (millis() - ts > 1000) {
+    Serial.println(sensor.getAngle(), 3);
+    ts = millis();
+  }
+  delay(1);
+}
+```
