Mar 30, 2023 · 请注意，我们使用的磁力计是内置在GPS模块中的那一个，当然你也可以购买一个同款磁力计连接上去。GPS的磁力计端口见下图的SCL、SDA。简而言之，把GPS模块的SCL、SDA分别与MPU6050的SCL、SDA，以及STM32相应的GPIO口连接到一起就可以了。 Mar 27, 2024 · 1. I2C is a serial communication protocol, so data is transferred bit by bit along a single wire (the SDA line). The SDA wire is used for sending the actual data back and forth between the master and slave devices. Related Guides Adafruit MMA8451 GPS works best if the GPS receiver is mounted above and away from other sources of interference. 将导航板的I2C接口（一般就是A4，A5）与飞空版的I2C相互连接。 注意这里A4连A4，A5连A5. 3v, not 5.

J'ai un module GPS avec 6 connecteurs, je n'utilise que 3 connecteurs pour qu'il fonctionne: "VCC, GND, TX" (Je n'utilise pas le RX) J'ai aussi des connecteurs SDA et SCL sur mon module GPS, j'aimerai pouvoir utiliser ceux-ci plutôt que d'utiliser le RX. A hardware serial port is your best option for a stable and reliable connection. These pins have 10K pullups to Vin. The SDA and SCL resources of an MCU are only usable by specific MCU pins, which means you can remap the SDA and SCL resources to those permitted pins as long as the pins aren't already being used for something else. The other two pins, SCL and SDA, are nothing to do with the GPS. So RC is inverted RX1 for SBUS. RESOURCE i2c mapped to B10 and B11 automatically - I checked in the CLI. Sosince I don’t use DJI on UART 4 it’s not being used and I was hoping there was a way to remap SDA/SCL to UART 4 so I have a compass and GPS. Board information It has NEO-M8N GPS receiver that has aGPS (Assist GPS) with cold start (Time To First Fix) of about 25 sec. I2C bus signal cross-talk and electromagnetic compatibility can be greatly improved by proper twisting of the cable wires. The remainder of the procedure is exactly as explained for the APM 2.
