Setup DescriptionMCU: STM32G070REPeripherals:ADC1 sampling 11 channels (IN0–IN8, IN17, IN18).DMA1 Channel1 configured circular, PERIPH→MEMORY, increment on memory.Timer 15 used to generate a 3 ms integration window (for TPIC8101 knock sensor).CC1 = s...
My timer setup in input capture mode. The ICPrescaler value is set to TIM_ICPSC_DIV2, meaning a capture event will occur on the falling edge of every second pulse. I need to handle an edge case where I need to "reset" the whole input capture system....
I am using the STM32U575 on a custom board and see that AN2606 indicates PG10 becomes a SPI MISO output in bootloader mode. I would like to connect this same SPI port to another device with the STM32 in master mode for the user application. In order ...
As the title says, the STM32G47 PA9 pin appears to be set high in boot mode opposed to pulled high though a resistor which is states in AN2606. This is becoming a problem because it introduces negative behaviors in our design when we try to reprogram...
Hello guys.I designed a custom board around the STM32F411CEU6. On this board, I have a switch and a screw terminal header, both of which are intended to be used has GPIO inputs. However, with both I've had a struggle working with GPIO inputs and inte...
I have been struggling with this chip for a few days now. I have code up for the STM32F072, and the STM32F100 series chips, but the GPDMA in the STM32U535 is baffling me. And no, I am not a big fan of the product notes for the GPDMA, while I've gon...
The codebase is generated by CubeMX and now I'm facing issues during debug.debug method is SWD using ST-LINK V2.In debug mode, after resume fron HAL_Init(); , the code will crashed into system memory zone and have no debug information.Break at addres...
Hi, I'm seeking some advice on using a STM32U5A5 in USB device only via a USBC connection.Any previous USB "device only" designs I've worked on only required connections to D+, D- and ground to communicate. These designs have been USB2x.The U5A5 has ...
Dear ST Support Team,I am developing a USB-based device using the STM32H755 microcontroller.In order to ensure proper identification of the device on host systems, I would like to requestthe allocation of a unique USB Product ID (PID) under STMicroel...
Hi,I am using STM32H7B0Since it has only 128KB flash, I will need to use an external flash to run code. There will be a "host" mcu to control this (with BOOT0 / NRST pin control).I am wondering is it possible to use the built-in ROM bootloader (in sy...
