I am using ST-LINK/V2 RoHS module in this module we have 20 Pins.
without SWCLK and SWDIO pin I need to program.
[enter image description here][1]
in this following pin diagram we have RX and TX can we flash the program using that.
let me know

I connected the PCM1860 ADC in this manner. I expect data on my oscilloscope on the digital output (pin 18). I have so far only seen square wave on the clock pins but nothing on the data pin. Is this connected ok?
If i want to use mpu6050 intterrupt to wake up stm32.
when i move my board,stm32 can wake up form stop mode.
i have realized the iic communication between stm32 and mpu6050.and stm32 can already enter stop mode.
I'm using the STM32L496 and attempting to use the CAN interface with the embedded bootloader. I know I can put it into the bootloader, I can see the bootloader mapped to memory zero-address. And I can see the HSI is checked and system clock set to 72MHz as it should. However, when I attempt to send the first CAN frame (which should kick off the CAN command loop), the device resets. If I have boot0 high, it will reset to the application, but if I hold it low it will reset to the bootloader again.
I have a 24MHz oscillator connected to the HSE pins. Why does the device reset when I send a CAN frame (any CAN frame)?
I am currently making a system using digital camera, my camera resolution is 384x288 4:2:2 YCbCr. My camera works on BT.656 with embedded sync (without hardware sync).
I configured STM32 DCMI with embedded sync and it didn't work. Then I started to debug it and found some weird STM32 DCMI issue:
STM32 DCMI embedded for BT.656 is inverted.
STM32 DCMI document (out of ST's
AN5020):
BT.656 Protocol (from
here):
I have 2 questions:
Has anyone been able to make BT.656 work on STM32H7 or any STF32FXX?
BT.656 resolution for PAL is 720x576 but my camera is 384x288.
What is the format of the camera?
Or: How can I understand how many lines are used?
I am trying to use the RPI 3's hardware PWM pin.
Is there a simple Bash script or C program that activates and controls the PWM pin?
WiringPi has written a GPIO utility for testing against the Raspberry GPIO pins. It includes PWM functionallity. Check it out on http://wiringpi.com/the-gpio-utility/
