Hello everybody,I am trying to synchronize the ADC1 and ADC2 to work with center-aligned PWM signals in dual-simultaneous regular mode using DMA. My setup:PWM frequency: 5.2 kHZADC conversion frequency: 104/2 = 52 MHZIf I have 3 conversions per ADC w...
I am trying to source a 12.288MHz clock for an STM32L433 but having difficulties finding something.The clock is required for I2S playback with a bluetooth receiver (BT401).I have tried using the internal MSI RC to generate the 12.288MHz clock for SA...
I am trying to do OTA programming modifications using the DUAL bank feature of my STM32U575 IC with 1Mbyte of memory.I have successfully done this when the program starts in BANK 1 and I reflash BANK 2. I change the User Option byte to OB_SWAP_BANK_E...
Hello everyone,We are having trouble getting tracing to work with our target at full clock speed and would like to understand why, we have an application running on STM32U575 @ 160MHz CPU clock, we also connected the J-Tracer to it using a connector ...
What is meant by watermark concept in chromArt Controller, Whats the application of it can you explain in detail and clearly
I am facing very weird issue in STM32 ADC.1. I used single channel in polling mode and interrupt mode the value i got was 4095, even the pin voltage was 1.7V, i used DSO to look for any serious noise on the pin but it was clean.Also if i gave 0V to t...
I created a custom STM32F411 PCB. I can program it and blink a LED for example just fine. I also have a STM32 blackpill board which uses the same MCU. When I run some USB HID code it works fine on the blackpill but once uploaded to my custom PCB and ...
Hello everyone, I am working on a project related to CAN communication, and I don't have complete knowledge about the RTR Remote and RTR DATA features within CAN. Should I use RTR Remote in a complex system?
Hi There,So, I got some of the STM32C011J6 MCUs for my simple project of reading sensors data and generating an interrupt.But I am in a dilemma, that the MCU's has I2C Pins, SWD Pins for programming, GPIO pins to act as interrupt but how to initializ...
Been reading thru the F103 datasheet to try and figure out why my TinyUSB based code isn't working. The datasheet says.. "For mono-directional/single-buffer endpoints, a single register can be used to implement two distinct endpoints". The F103 has...
