STC32 USB-CAN Communication Module

USB to CAN converter

Project Description
Main Functions:
1. USB-CAN communication module
2. Message display with OLED
3. WIFI module, can connect to host computer via WIFI
Schematic:
Core peripheral circuit Future Studio's reference minimum system, no serial port version
https://oshwhub.com/wei-lai-dian-zi-gong-zuo-shi/zui-xiao-xi-tong-stc32g12k128-hid-xia-zai
WIFI interface, ESP01S
uses two CAN channels, the chip is the domestic SIT1042T.
Verification effect, power supply test OK, using STC-ISP software, operation is consistent with the manual, but it is not recognized, and the STC USB Writer is not displayed. The board was resoldered once, but it is still the same. However, I am using the same chip. I suspect that the chip may be broken. I have been struggling with it for a long time, so I gave up on
the physical pictures.

The STM32F103 flight controller uses Naza firmware.

Based on the STM32F103 flight controller, the pins are designed according to the Naza firmware.

Reserved PWM (unverified)
onboard brushed driver (verified and test-flown)
with 1s power supply.

Minimum system and procedures for controlling servo motors

It can control four servos, plus a P0 expansion port.

Project Functionality This design is based on the STC89C51/52 microcontroller and is a minimum system software code
for controlling a servo motor. #include "reg52.h" #include "intrins.h" #include "TMER0.H" sbit S1=P0^0; sbit S2 =P0^1; sbit SG_PWM1=P2^0; sbit SG_PWM2=P2^1; sbit SG_PWM3= P2^2; sbit SG_PWM4=P2^3; unsigned char count=0; unsigned char PWM1_count=0; unsigned char PWM2_count=0; unsigned char PWM3_count=0; unsigned char PWM4_count=0; void Delay1ms(unsigned int xms ) //@11.0592MHz { while(xms) { unsigned char data i, j; i = 15; j = 90; do { while (--j); } while (--i); xms--; } } void main() { Timer0_Init(); S1 = 1 ; PWM1_count=1; Delay1ms ( 100) ; Delay1ms(100); PWM1_count=3; Delay1ms (100) ; PWM2_count=3; Delay1ms (100); PWM3_count = 3 ; Delay1ms ( 100 ) ; PWM1_count=3; PWM4_count=3; } else { PWM1_count=1; PWM4_count=1; Delay1ms(100); PWM2_count=3; PWM3_count=3; } } } unsigned int T0Count; void Timer0_Routine() interrupt 1 { TL0 = 0x33; //???????

Note:
For cold start downloading of the microcontroller, when using the P0 serial port, you need to solder pull-up resistors yourself. Also,
please note
that the Comtasia company logo is from the Cyberpunk 2077 game; any resemblance is purely coincidental.
