Crsf2Pwm_Air001

Overview

The wiring looks terrible. I rewrote the code myself using the open-source CRServoF to adapt it to the air001 chip.
Thanks to LCSC for providing the board for free; one air001 chip, about 10 resistors and capacitors, one LED, pin headers, and headers cost less than 1 yuan.

Due to the accuracy of the voltage divider resistors, you'll need to adjust the coefficients yourself.
When connected to the flight controller, there's a 1-2 ohm fluctuation in the data across each channel. I wonder if conversion modules costing tens of yuan have this kind of fluctuation. If anyone knows, please let me know in the comments.

The code is attached;
the programming parameters are shown in the image.

Future plans:
1. Optimize the programming and parameter tuning interface.
2. Change the PWM interface order to make the wiring more elegant.
3. Support PPM output in the code.

Why does the Quartus II 10.1 synthesis result use 0 cells?
Why does the result of Quartus II 10.1 synthesis use 0 units? There is no error, I can see the RTL view and the synthesized network device has been selected. There is a prompt saying that the clock is
ADI Experimental Circuit CN0197 Battery Management System Based on AD7280A Phase II Report
It has been more than a week since I last reported on the progress of my work. During this week, the first surprise was the delivery of the samples. The sample AD7280A I applied for is difficult to bu
DM642 audio port McASP problem
I recently learned about TMS320DM642 and used the McASP audio port to send data to the data port of TLV320AIC23B. There was no error in the process of configuring the register of AIC23B through the I2
Using LM2903 to complete 3.3V and 5V level conversion [Figure]
The OC gate structure of LM2903 is used to complete the level conversion circuit between 3.3V and 5V. The 3.3V DSP serial port needs to communicate with the 5V CMOS device (camera), and a level conver
