I need to measure the On and Off times of a possibly asymmetric signal. Measuring frequency is a classic TIM Input Capture function, and in this case one is tempted to set the capture for both edges. Within the ISR, however, is there a HAL approved...

HiTrying to configure a 48-pin STM32G0C1CE project in STMCubeIDE 1.9.0., specifically configuring pin 23/PB11 as ADC1_IN15. The embedded MX tool chip pinout view allows one to select pin 23 as ADC1_IN15, but then leaves PB11 yellowed in the overall ...

I'm working on test code for a bare metal STM32G0C1 project. I'm using STM32CubeIDE 1.9.0 and created the project with the included STMCubeMX tool.When digging around in the generated code to understand I2C I found that the function HAL_I2C_MspInit(...

Is it possible in the STM32 world to have two synchronized PWM - but with an offset separating the outputs?Here's the problem in picture form:Both the blue and red traces are the same frequency and duty cycle, but in this case trace red is offset 50 ...

I have a circumstance where two PWM outputs are required, and they must be precisely coupled together. A number of the other big guy's LPC micros included an SCTimer/PWM (that's State Configurable Timer...) which, without too much magic, allows a fi...

Ah, ha! I found it! You can stand down. HAL_I2C_MspInit() is defined. It is in Core/Src/stm32g0xx_hal_msp.c. The brute-force searches I was doing earlier seem to only show the Drivers/STM32G0XX_HAL_Driver/Src/STM32g0xx_hal_i2c.c. That's where t...

I've already got I2C2 defined, pins allocated, and all that via the embedded STMCubeMX. I discovered all of the above because I've got to switch pin definitions at run time. I need to temporarily define I2C1 as alternate functions on PA10 / PA9. I...

Hey KnarfB:Thanks for your response! I threw your recommendations into a quick STM32G031-Nucleo project and got the dual synchronized outputs you promised (although quite different from your trace). I need to study your solution and (hopefully) twe...

Thanks all for your responses. Yes, the info is in the reference manual but I wasn't sure what it was called in STM32-speak and was looking for help zeroing in on it (or somebody knows it CAN'T be done, knowing that upfront would be good to know). ...

Thanks for your comments. I'm hot into the manuals at this moment and have noted repeated references to "timer synchronization" which sounds like what I am seeking to replicate but in STM-speak rather than NXP-speak. I've got some Nucleo's and will...
